GENERAL INFORMATION
Method of Notation
This manual contains directions and information that apply to the PM6690 Timer/Counter/Analyzer. In order to simplify the references,
the following designation system is used throughout the manual:
– PM6690 is abbreviated to '90'.
Warranty
The Warranty Statement is included in the Getting Started Manual.
Declaration of Conformity
The complete text with formal statements concerning product identification, manufacturer and standards used for type testing is avail-
able on request.
Hardware Versions
This Service Manual provides Source of Supply information for the Fluke Model PM6690 Timer/Counter/Analyzer, which may con-
tain an OLD version of the Main CCA, called Version A, or a NEW version of the Main CCA, called Version B. Both the old and the
new version of the Main CCAhave the same part number. All orders for the old version of the Main CCAwill be filled with the new ver-
sion of the Main CCA. When the old version of the Main CCA is returned to the factory for repair, the new version of the Main CCA
will be returned in place of the old version of the Main CCA, if the microprocessor has to be replaced.
Devices with serial numbers up to and including 916779 are equipped with a Triscend microprocessor, whereas devices with higher se-
rial numbers have a Sharp microprocessor. Both are based on an ARM7 core, and from the operator’s point of view the behavior is not
affected. However, essential parts of the main PCB differ, and the corresponding sections of the service manual are consequently af-
fected. Even though large parts of the hardware are common to both versions, we have preferred to divide the pertinent chapters into
separate sections, where certain parts are repeated, all in order to improve legibility and simplify troubleshooting.
Version A refers to devices equipped with the Triscend microprocessor.
Version B refers to devices equipped with the Sharp microprocessor.
The chapters that need special attention are:
Chapter 4, Circuit Descriptions
Chapter 6, Repair
Chapter 8, Replacement Parts
Chapter 9, Schematic Diagrams
� Firmware Compatibility
Despite the relatively large hardware differences, we have managed to integrate the firmware, so that future upgrades can be applied to
both versions by means of the same hex file. Thus there is no need to check the serial number or else find out which processor is inside
the cover. Just proceed according to the instructions given in Chapter 5, Corrective & Preventive Maintenance.

WARNING: These servicing instructions are
for use by qualified personnel only. To re-
duce the risk of electric shock, do not
perform any servicing other than that
specified in the Operators Manual unless
you are fully qualified to do so.
Caution and WarningStatements
Introduction
Read this chapter carefully before you check, adjust or repair
the instrument.
It is essential for your own safety to know the restrictions that
are applicable to all equipment that can be connected to line
power. Therefore, read the section on Safety Precautions be-
low.
In addition to the general statements given in this chapter you
will find specific caution and warning statements where nec-
essary throughout the manual.
Safety Precautions
This instrument has been designed and tested for Measurement Cate-
gory I, Pollution Degree 2, in accordance with EN/IEC
61010-1:2001 and CAN/CSA-C22.2 No. 61010-1-04 (including ap-
proval). It has been supplied in a safe condition.
This manual contains information and instructions that should
be followed by the user and the service technician to ensure
safe operation and repair in order to keep the instrument in a
safe condition. It is essential that you follow generally ac-
cepted safety procedures in addition to the safety precautions
specified in this manual.
The instrument is designed to be used by trained personnel
only. Removing the cover for repair, maintenance, and adjust-
ment of the instrument must be done by qualified personnel
who are aware of the hazards involved.
The warranty commitments are rendered void if unautho-
rized access to the interior of the instrument has taken
place during the given warranty period.
CAUTION: Indicates where incorrect proce-
dures can cause damage to, or destruction
of equipment or other property.
WARNING: Indicates a potential danger that
requires correct procedures or practices
to prevent personal injury.
Symbols
Shows where the protective ground terminal is con-
nected inside the instrument. Never remove or
loosen this screw.
Indicates that the operator should consult the manual.
You can, for instance, find such a symbol on the front
panel below the A and B inputs. It points out that the
damage level for the input voltage decreases from 350 Vp to
12 Vrms when you switch the input impedance from 1 M� to
50 �.
If in Doubt about Safety
Whenever you suspect that it is unsafe to use the instrument,
you must make it inoperative by doing the following:
– Disconnecting the line cord
– Clearly marking the instrument to prevent its further op-
eration by unauthorized personnel
For example, the instrument is likely to be unsafe if it is visi-
bly damaged.
Grounding
Grounding faults in the line voltage supply will make any in-
strument connected to it dangerous. Before connecting any
unit to the power line, you must ensure that the protective
ground functions correctly. Only then can a unit be connected
to the power line and only by using a three-wire line cord. No
other method of grounding is permitted. Extension cords must
always have a protective ground conductor.
CAUTION: If a unit is moved from a cold to
a warm environment, condensation may
cause a shock hazard. Ensure, therefore,
that the grounding requirements are
strictly met.
WARNING: Never interrupt the grounding
cord. Any interruption of the protective
ground connection inside or outside the
instrument or disconnection of the protec-
tive ground terminal is likely to make the
instrument dangerous.
Operation
Orientation and Cooling
The instrument can be operated in any position desired. Make
sure that the air flow through the ventilation slots at the top,
1-2 Safety Instructions
and side panels is not obstructed. Leave 5 centimeters (2
inches) of space around the counter.
Fold-Down Support
For bench-top use, a fold-down support is available for use
underneath the counter. This support can also be used as a
handle to carry the instrument.
Rackmount Adapter
If you have ordered a 19-inch rack-mount kit for your instru-
ment, it has to be assembled after delivery of the instrument.
The rackmount kit consists of the following:
– 2 brackets, (short, left; long, right)
– 4 screws, M5 x 8
– 4 screws, M6 x 8
WARNING: Do not perform any internal ser-
vice or adjustment of this instrument
unless you are qualified to do so.
Before you remove the cover, disconnect
mains cord and wait for one minute.
Capacitors inside the instrument can hold
their charge even if the instrument has
been separated from all voltage sources.
� Assembling the Rackmount Kit
– Make sure the power cord is disconnected from the in-
strument.
– Turn the instrument upside down.
See Fig. 1-3.
– Undo the two screws (A) and remove them from the
cover.
– Remove the rear feet by undoing the two screws (B).
– Remove the four decorative plugs (C) that cover the
screw holes on the right and left side of the front panel.
– Grip the front panel and gently push at the rear.
– Pull the instrument out of the cover.
– Remove the four feet from the cover.
Use a screwdriver as shown in the following illustration or a
pair of pliers to remove the springs holding each foot, then
push out the feet.
– Push the instrument back into the cover. See Fig. 1-3.
– Mount the two rear feet with the screws (B) to the rear
panel.
– Put the two screws (A) back.
– Fasten the brackets at the left and right side with the
screws included as illustrated in Fig. 1-1.
– Fasten the instrument in the rack via screws in the four
rack-mounting holes

Fig. 1-3 Remove the screws and push the counter out of the
cover.
Fig. 1-4 Removing feet from the cover.
The long bracket has an opening so that cables for Input A, B,
and C can be routed inside the rack.
� Reversing the Rackmount Kit
The instrument may also be mounted to the right in the rack.
To do so, first remove the plate on the long bracket and fasten
it on the short one, then perform the preceding steps.
Line Voltage
� Setting
The Counter may be connected to any AC supply with a volt-
age rating of 90 to 265 Vrms, 45 to 440 Hz. The counter auto-
matically adjusts itself to the input line voltage.
� Fuse
The secondary supply voltages are electronically protected
against overload or short circuit. The primary line voltage side
is protected by a fuse located on the power supply unit. The
fuse rating covers the full voltage range. Consequently there
is no need for the user to replace the fuse under any operating
conditions, nor is it accessible from the outside.
CAUTION: If this fuse is blown, it is likely
that the power supply is badly damaged.
Replace the complete power supply unit.
Do not replace the fuse.
1-4 Safety Instructions
General Information
WARNING: Before turning on the instru-
ment, ensure that it has been installed in
accordance with the Installation Instruc-
tions outlined in Chapter 1 of the
Operators Manual.
This performance procedure is intended for:
– checking the instrument’s specification.
– incoming inspection to determine the acceptability of
newly purchased instruments and recently recalibrated
instruments.
– checking the necessity of recalibration after the specified
recalibration intervals.
NOTE: The procedure does not check every facet of the in-
strument’s calibration; rather, it is concerned primarily
with those parts of the instrument which are essential
for determining the function of the instrument.
It is not necessary to remove the instrument cover to perform
this procedure.
Test Equipment
Preparations
Power up your instrument at least 30 minutes
before checking to let it reach normal operating
temperature. Failure to do so may result in cer-
tain test steps not meeting equipment specifications.
Front Panel Controls
Internal Self-Tests
The test programs forming the self-diagnosis can be activated
from the front panel as follows:
– Press USER OPT
– Press Test.
– Press Test Mode.
– Select one of the six tests available by pressing the
softkey below the label with the name of the test func-
tion. Five of the tests (RAM, ROM, Logic, Display, and
Interface) are individual. They are briefly described be-
low. The sixth, named All, performs all five individual
tests in sequence.
• All - all tests performed in sequence
• RAM - test of RAM memory
• ROM - test of ROM memory
• Logic - test of counter ASIC and other logic circuits.
• Display - test of graphic displaymodule
• Interface - test of GPIB and USB
– Press Start Test.
– If a fault is detected, an error message appears on the
display and the program halts. Note any error messages.
– If no faults are detected, the instrument returns to the
normal measurement mode.
Keyboard Test
See Table 2-3. This test verifies that the timer/counter re-
sponds when you press any key. It is not a functional test.
Such tests are performed later in this chapter. The important
thing here is that something changes on the display when you
press a key. Consequently you can press the keys in almost
any order without paying attention to the exact response, but
for those who want to be more systematic there is a table over-
leaf, where all keys are exercised at least once.
Press the keys as described in the first column and look at the
display for the text in the second column. Some keys change
more text on the display than described here. The display text
mentioned here is the one mostly associated with the selected
key.
NOTE: For the instrument to respond correctly, this test
must be carried out in sequence and you must start
with the DEFAULT setting. Do as follows:
– Press USER OPT.– Press Save/Recall.– Press Recall Setup.– Press Default.
See Table 2-2 for the complete list of default settings.

Reference Oscillators
X-tal oscillators are affected by a number of external condi-
tions like ambient temperature and supply voltage. Aging is
also an important factor. Therefore it is hard to give limits for
the allowed frequency deviation. The user himself must de-
cide the limits depending on his application, and recalibrate
the oscillator accordingly.
To check the accuracy of the oscillator you must have a cali-
brated reference signal that is at least five times more stable
than the oscillator that you are testing. See Table 2-7 and the
list of test equipment on page 2-2. If you use a non-10 MHz
reference, you can use the mathematics in the timer/counter to
multiply the reading.
– Recall the DEFAULT settings. See page 2-2
– Connect the reference to input A
– Check the readout against the accuracy requirements of
your application.

Block Diagram Description
General
The PM6690 Timer/Counter consists of three main units:
– Front unit
– Main printed circuit board
– Rear panel unit
Several options exist:
– Prescalers on separate PCBs covering different fre-
quency ranges (3 GHz and 8 GHz)
– Two OCXO timebases (very high & ultra-high stability)
– Rackmount kit
The chassis of the counter consists of a front piece molded in
aluminum, an aluminum rear panel, and two extruded alumi-
num bars that hold the front and rear panels together. This unit
can be slid into the aluminum cover of the instrument.
The main circuit board is fixed to the two bars. The display
circuit board is fixed to the front piece. A detachable connec-
tor joins the electronics of the front unit and the main board,
and the molded front piece is fixed with screws to the two alu-
minum bars. The rear panel is also fixed to the bars with
screws.
The front unit contains all functions needed for the user com-
munication: keyboard, display and input BNCs. All other
electrical functions are on the main board. The rear panel has
no PCB. The connectors here are all soldered directly to the
main circuit board.
Block Diagram
Figure 4-1 contains a block diagram of the electrical functions
of the counter. They are divided among the main circuit board,
the display board, the rear panel and the optional prescaler
board. See the schematic diagrams in Chapter 9 for complete
information.
Most functions are placed on the main board:
– Input amplifiers with trigger level circuits
– Power supply
– Measurement logic
– Microcomputer circuitry
– GPIB interface
– USB interface
– External reference input
– External arming input
The rear panel unit is made of aluminum with a number of
mounted connectors, a fan and a power line inlet with filter.
Most connectors are soldered directly to the main board.

Hardware Functional Description
Front Unit
The front unit consists of a front piece in molded aluminum, a
silicon rubber keypad with conducting contact surfaces, a
graphic LCD with LED backlight, and a PCB having etched
gold-plated keyboard contacts and a dedicated LCD power
supply.
Display
The display is a 320*97 pixels graphical LCD with LED
backlight. The LCD controller is part of the processor, and it
sends data and control signals to the drivers in the LCD mod-
ule. Display ON is controlled via the I2C bus and the keyboard
IC. The LCD voltages are generated by a DC/DC converter.
Five different voltages are generated. A control signal from
the processor switches the converter ON/OFF and also sets
the contrast of the display.
The 4 LEDs on the display board are controlled from the mea-
suring logic and the ON/OFF circuit.
Keyboard
The PCB covers the back of the front unit. The keys are laid
out as a crosspoint switch matrix consisting of 25 regular push
buttons plus a special power button. When one of the buttons
is depressed, the dedicated keyboard IC U3 responds by
sending an interrupt to the processor. The processor scans the
keyboard over the I2C bus to find out which button calls for
attention. The power button differs from the others by having
a dual function. In Standby Mode it turns on the ON/OFF cir-
cuit directly, but when the counter is ON, it is read as any other
button. Then the processor turns off the counter. This arrange-
ment is necessary since the processor is inactive in standby
mode.
Main Board
Input Amplifiers
Input amplifiers A and B are identical with >300 MHz band-
width. They are controlled by the processor with relays etc.
The analog input signal is transformed to a digital signal. The
output signals are LVPECL (+2.4 V and +1.2 V approxi-
mately) and fed to the measuring logic.
For a block diagram of the input amplifiers, see Figure 4-2.
� Impedance Selector
This stage selects 1 M� or 50 � input impedance with a relay.
In 50 � mode 11 resistors are used for dissipating the input
power, up to a maximum of 2.9 W (12 Vrms).
� Attenuator
This stage has two parts, a fixed preattenuator (approximate
attenuation ����) and a cascaded relay-operated ��/��� step
attenuator. The variable capacitors are used for adjusting the
frequency response of the attenuators.
� AC/DC
This stage selects AC or DC coupling with a relay.
� Limiter
The voltage limiter protects the impedance converter against
overvoltage. The �5 V applied to the input BNC is divided to
approximately �2.1 V by the attenuator. The limiter clamps
the voltage to approximately �2.8 V.
� Impedance Converter
Split-band technique is used for achieving good frequency re-
sponse over a wide range. The HF signal is fed via an
AC-coupled FET stage. The LF signal (bandwidth DC to ap-
proximately 10 kHz) goes via an operational amplifier. The
signals are added together at the source of the FET. The output
signal from the buffer stage (see below) is fed back to the op-
erational amplifier. A trimmer potentiometer is used for
equalizing the gain in the two signal paths (approximately
�0.9).
� Filter
A lowpass RC filter with an approximate cutoff frequency of
100 kHz can be switched in via a transistor.
� Buffer
Before the signal is fed to the Crossover Switch, it passes a
current-amplifying buffer stage that can drive the following
low impedance stages.
4-6 Hardware Functional Description
� Crossover Switch
This stage uses relays to direct the signal to the two compara-
tors. The following combinations are possible:
• IN A to COMP A and IN B to COMP B
• IN A to both COMP A and COMP B
• IN B to both COMP A and COMP B
� Comparator
The comparator converts the analog signal to a binary logic
signal, with ECL levels (-0.9 V and –1.7 V). The trigger point
is set by a voltage from the trigger level circuitry.
Temperature-compensated circuitry generates the voltages
that control the hysteresis of the comparator. A trimmer
potentiometer adjusts the hysteresis window.
� Trigger Level Generation
Two 12-bit DACs in a single IC generate the two trigger levels
for Channel A resp. Channel B. A 2.5 V DC reference IC sup-
plies the reference voltage to the DACs. The DACs are con-
trolled by the processor over the SPI bus. The �5 V dynamic
range at the BNC of the input amplifier is converted to ap-
proximately �2.1 V at the comparator. This range must be
covered by the DAC. The voltage step from the DAC is ap-
proximately 1.2 mV, corresponding to 2.9 mV per step at the
BNC. Closed Case Calibration (CCC) is used for adjusting
the trigger levels. A known reference level is applied to the
BNC and the processor finds out the appropriate setting of the
DAC to match the reference level.
� Logic Level Conversion
The signals from the comparators must be converted from
ECL levels to LVPECL levels. There are three converter cir-
cuits. One for Channel A , one for Channel B and one for the
Set-Reset channel. The two main channels are fed to a Set-Re-
set flip-flop to make one-channel measurements with variable
hysteresis possible. There is also a converter for the signal
from an optional prescaler. It has PECL levels (+4.1 V and
+3.4 V) that are converted to LVTTL levels (+2.4 V and 0 V).
Oscillator Circuits
The processor has a 32768 Hz crystal. An internal PLL in the
processor uses the 32 kHz signal to make the internal proces-
sor clock, approximately 30 MHz. The USB IC has a 6 MHz
crystal to make an internal clock and the GPIB IC has a 40
MHz crystal to make an internal clock.
The measurement reference oscillator (timebase) for the
timer/counter is a 10 MHz crystal oscillator or an optional
oven-controlled crystal oscillator (OCXO). Only one of these
is mounted. The user can also select an external reference sig-
nal, connected to the External Reference Input BNC on the
rear panel.
The standard oscillator consists of an inverter and a crystal.
The processor controls the frequency of the oscillator with a
PWM signal. The PWM signal is filtered to a DC level that
controls the capacitance of a capacitance diode. The varying
capacitance changes the frequency of the oscillator. The stan-
dard oscillator is adjusted with Closed Case Calibration. Ap-
ply a 10 MHz reference signal to Input A. The processor will
find the correct PWM signal to make the internal reference
frequency equal to the external reference frequency.
The optional oven-controlled oscillator is a complete oscilla-
tor in a small hermetic metal box. An internal accurate DC
voltage is available for use as a reference for a 12-bit DAC.
The filtered output voltage from the DAC sets the frequency
of the oven oscillator. The processor controls the DAC via the
SPI bus. The same Closed Case Calibration as for the stan-
dard oscillator is used. The oven oscillator is kept warm if the
line power is connected to the timer/counter, even if it is
switched off (in standby mode).

The 10 MHz reference signal is multiplied in a PLL to
100 MHz. The 100 MHz signal is used in the measuring logic
as a reference. The processor controls the PLL IC with the SPI
bus. A 100 MHz LC oscillator is used as the controlled ele-
ment where part of the C is a variable capacitance diode. Its
capacitance is controlled with a DC voltage from the PLL IC,
thus changing the frequency. The 10 MHz reference signal is
applied to the PLL IC as its reference and the 100 MHz output
frequency is exactly 10 times the reference frequency.
External Reference Input
A 1, 2, 5 or 10 MHz reference signal can be connected to the
rear panel BNC. After amplification in an operational ampli-
fier narrow pulses are made in two D flip-flops, one narrow
pulse for each input cycle. These pulses are fed to the 10 MHz
crystal filter. After the filter a reconstructed 10 MHz signal is
available. A variable capacitor is used for adjusting the filter.
Internal Reference Output
The selected 10 MHz reference signal (standard/oven oscilla-
tor or external reference) is available on the rear panel. The 10
MHz reference signal that is used internally by the dedicated
counter circuit (FPGA) logic is also sent to an output pin on
the FPGA. It is filtered to a sine wave and amplified in an out-
put buffer stage having 50 � drive capability.
Measuring Logic
The measuring logic consists of an FPGA, four interpolators
and an external control input on the rear panel. The FPGA
core uses +1.8 V supply voltage and the I/Os use +3.3 V sup-
ply voltage.
The FPGA is controlled by the processor over a 16-bit micro-
processor bus. Input signals (A, B, prescaler etc) and refer-
ence clock (internal 10 MHz oscillator or external reference)
are selected inside the FPGA. The logic for all measuring
functions and support functions (trigger indicators, start de-
lay, pacing etc) are inside the FPGA. A 100 MHz reference
clock is generated by a PLL circuit giving 10 ns basic mea-
surement resolution. To increase the measurement resolution
further, external interpolators are used. The measuring logic
also controls three LEDs on the display board; a GATE LED
indicating that a measurement is in progress, and two trigger
indicators telling that the comparators are triggering on the in-
put signals. A separate 32-bit bus is used for transferring mea-
surement data from the FPGA to the processor. Some control
signals to the hardware come from the FPGAdue to a shortage
of processor pins.
The four external interpolators are identical. Depending on
the selected measurement function 0, 2, 3 or 4 interpolators
are used. A pulse representing the time from an event on the
input to the following rising edge of the 100 MHz reference is
fed to the interpolator. During the pulse time a constant cur-
rent is charging a capacitor. The voltage on the capacitor is
measured with a 10-bit ADC. The capacitor is discharged and
the interpolator is ready for a new measurement.
An external control input BNC is located on the rear panel. A
signal applied to this connector can be used for controlling the
start of a measurement, for instance. A comparator converts
the analog input signal to a logic signal.
Processor Circuits
The processor is a Triscend A7S. It contains an ARM7 core
and peripherals. It runs on a 30 MHz internal clock. The core
uses 2.5 V supply voltage and the I/Os use 3.3 V supply volt-
age.
A separate memory bus communicates with a 16-bit 8 MByte
flash memory and a 32-bit 32 MByte SDRAM. The flash
memory contains the program, data for loading the FPGA,
and stored data (calibration data etc.). At power-up the code is
copied from the flash to the SDRAM. It is run from the
SDRAM for faster execution.
The processor has a JTAG interface with a connector on the
circuit board.
A reset IC monitors the three main logic supply voltages, +3.3
V, +2.5 V and + 1.8 V. If a supply voltage fails, the processor
will be reset.
The regular 16-bit microprocessor bus is used for controlling
the FPGA, the GPIB interface and the USB interface. A sepa-
rate 32-bit bus is used for fetching measurement data from the
measuring logic.
Two other buses are also used, an SPI bus and an I2C bus. The
SPI bus is an output only bus and the processor controls the
100 MHz PLL, the trigger level DACs, and the DAC for the
optional oven oscillator. The I2C bus is bidirectional and used
for communication with the temperature measurement IC, the
display board (keyboard + LCD), the prescaler (optional), and
the relays and filters in the input amplifier.
The temperature reading over the I2C bus is used for con-
trolling the fan speed. A PWM output is utilized. The signal is
filtered and the resulting DC voltage controls the fan.
Another PWM output is used for controlling the frequency of
the standard crystal oscillator.
The LCD controller is a peripheral inside the processor. This
controller sends signals and data to the driver circuits in the
LCD on the display board.
The processor also controls the OFF switch. Only a signal
from the processor can switch off the power. The OFF button
on the front panel is read by the processor. ON is handled
without the processor, since it cannot respond to external
stimulus in standby mode.
Power Supply
This timer/counter has no primary power switch. If connected
to line power there are live parts inside the cabinet, and some
supply voltages are present on the main circuit board, even if
4-8 Hardware Functional Description
the secondary power switch on the front panel has been turned
off (standby mode).
A semi-protected AC/DC module is placed on spacers over
the main circuit board. It delivers three regulated DC voltages
to the counter, + 15 V, + 5 V and –15 V. When the counter is
connected to line power, these voltages are always present.
There is a + 5 V trimmer potentiometer on the AC/DC mod-
ule.
The ON/OFF circuit is active as soon as the counter is con-
nected to line power. The instrument automatically powers up
when line power is applied. Only the processor can switch the
circuit to OFF state (standby mode). Then only the power but-
ton on the front panel can switch the instrument to ON. Once
connected to line power and in OFF state (standby mode),
supply voltage +12 VU is distributed to the oven oscillator to
keep it warm. In standby mode a red LED is lit on the front
panel. To keep the AC/DC module stable in this mode, a
dummy load is connected to draw a quiescent current of 0.1 A
at +5 V.
The three main voltages are +15 V, +5 V and –15 V from the
AC/DC module. All other supply voltages are generated from
them and are, except for +12 VU to the oven oscillator,
switched off in standby mode.
Linear regulators are used for generating stable voltages with
low noise and without spikes. Some of them have a resistor
net at the input to dissipate part of the heat generated. Thus the
regulator itself will run cooler. The following voltages are
generated in this way:
+3.3 VA from +5 VU
-5.2 VA from -15 VU
-5.2 VI from -12 VA
-2.1 V from -12 VA
-12 VA from -15 VU
+12 VA from +15 VU
+12 VU from + 15 VU, to oven oscillator, not switched off in
standby mode
For digital and general use supply voltages are generated by
DC/DC converters:
+3.3 VD from +5 VU
+5 VD from +5 VU via a switch IC
+15 VD from +15 VU via a switch transistor
+2.5 V from +5 VU
+1.8 V from +5 VU
Communication Interfaces
Both a GPIB and a USB interface are available for communi-
cation with external bus controllers. The connectors are lo-
cated on the rear panel.
The GPIB consists of an IC. Only 8 bits of the 16-bit micro-
processor bus is used. Due to different supply voltages for the
processor (+3.3 V) and the GPIB circuit (+5 V), a buffer IC is
used for isolating the +5 V GPIB IC from the processor bus. A
40 MHz crystal is used for generating a local clock.
The USB consists of an IC. It communicates with the proces-
sor over the 16-bit microprocessor bus. A 6 MHz crystal is
used for generating a local clock.
Rear Panel Unit
The rear panel is made of aluminum. A number of connectors
mounted on this unit are accessible to the user, see Figure 4-3.

Prescaler Circuit Board
There are several different optional prescalers available with
different frequency ranges. The prescaler is located on a sepa-
rate circuit board that is connected to the main circuit board
with a PCB connector.
A typical prescaler consists of a limiter, an amplifier, a fre-
quency divider, and a detector. The limiter and the amplifier
condition the input signal so that the amplitude to the divider
is constant. The divider scales the input signal so that it can be
handled by the measuring logic on the main circuit board. A
detector switches off the output signal from the divider if the
input level is too low for the divider to work correctly (divid-
ers often oscillate without input signal).

Block Diagram Description
General
The PM6690 Timer/Counter consists of three main units:
– Front unit
– Main printed circuit board
– Rear panel unit
Several options exist:
– Prescalers on separate PCBs covering different fre-
quency ranges (3 GHz and 8 GHz)
– Two OCXO timebases (very high & ultra-high stability)
– Rackmount kit
The chassis of the counter consists of a front piece molded in
aluminum, an aluminum rear panel, and two extruded alumi-
num bars that hold the front and rear panels together. This unit
can be slid into the aluminum cover of the instrument.
The main circuit board is fixed to the two bars. The display
circuit board is fixed to the front piece. A detachable connec-
tor joins the electronics of the front unit and the main board,
and the molded front piece is fixed with screws to the two alu-
minum bars. The rear panel is also fixed to the bars with
screws.
The front unit contains all functions needed for the user com-
munication: keyboard, display and input BNCs. All other
electrical functions are on the main board. The rear panel has
no PCB. The connectors here are all soldered directly to the
main circuit board.

Hardware Functional Description
Front Unit
The front unit consists of a front piece in molded aluminum, a
silicon rubber keypad with conducting contact surfaces, a
graphic LCD with LED backlight, and a PCB having etched
gold-plated keyboard contacts and a dedicated LCD power
supply.
Display
The display is a 320*97 pixels graphical LCD with LED
backlight. The LCD controller is part of the processor, and it
sends data and control signals to the drivers in the LCD mod-
ule. Display ON is controlled via the I2C bus and the keyboard
IC. The LCD voltages are generated by a DC/DC converter.
Five different voltages are generated. A control signal from
the processor switches the converter ON/OFF and also sets
the contrast of the display.
The 4 LEDs on the display board are controlled from the mea-
suring logic and the ON/OFF circuit.
Keyboard
The PCB covers the back of the front unit. The keys are laid
out as a crosspoint switch matrix consisting of 25 regular push
buttons plus a special power button. When one of the buttons
is depressed, the dedicated keyboard IC U3 responds by send-
ing an interrupt to the processor. The processor scans the key-
board over the I2C bus to find out which button calls for atten-
tion. The power button differs from the others by having a
dual function. In Standby Mode it turns on the ON/OFF circuit
directly, but when the counter is ON, it is read as any other
button. Then the processor turns off the counter. This arrange-
ment is necessary since the processor is inactive in standby
mode.
Main Board
Input Amplifiers
Input amplifiers A and B are identical with >300 MHz band-
width. They are controlled by the processor with relays etc.
The analog input signal is transformed to a digital signal. The
output signals are LVPECL (+2.4 V and +1.2 V approxi-
mately) and fed to the measuring logic.
For a block diagram of the input amplifiers, see Figure 4-8.
� Impedance Selector
This stage selects 1 M� or 50 � input impedance with a relay.
In 50 � mode 11 resistors are used for dissipating the input
power, up to a maximum of 2.9 W (12 Vrms).
� Attenuator
This stage has two parts, a fixed preattenuator (approximate
attenuation ����) and a cascaded relay-operated ��/��� step
attenuator. The variable capacitors are used for adjusting the
frequency response of the attenuators.
� AC/DC
This stage selects AC or DC coupling with a relay.
� Limiter
The voltage limiter protects the impedance converter against
overvoltage. The �5 V applied to the input BNC is divided to
approximately �2.1 V by the attenuator. The limiter clamps
the voltage to approximately �2.8 V.
� Impedance Converter
Split-band technique is used for achieving good frequency re-
sponse over a wide range. The HF signal is fed via an
AC-coupled FET stage. The LF signal (bandwidth DC to ap-
proximately 10 kHz) goes via an operational amplifier. The
signals are added together at the source of the FET. The output
signal from the buffer stage (see below) is fed back to the op-
erational amplifier. A trimmer potentiometer is used for
equalizing the gain in the two signal paths (approximately
�0.9).
� Filter
A lowpass RC filter with an approximate cutoff frequency of
100 kHz can be switched in via a transistor.
� Buffer
Before the signal is fed to the Crossover Switch, it passes a
current-amplifying buffer stage that can drive the following
low impedance stages.
4-14 Hardware Functional Description
� Crossover Switch
This stage uses relays to direct the signal to the two compara-
tors. The following combinations are possible:
• IN A to COMP A and IN B to COMP B
• IN A to both COMP A and COMP B
• IN B to both COMP A and COMP B
� Comparator
The comparator converts the analog signal to a binary logic
signal, with ECL levels (-0.9 V and –1.7 V). The trigger point
is set by a voltage from the trigger level circuitry. Tempera-
ture-compensated circuitry generates the voltages that control
the hysteresis of the comparator. A trimmer potentiometer ad-
justs the hysteresis window.
� Trigger Level Generation
Two 12-bit DACs in a single IC generate the two trigger levels
for Channel A resp. Channel B. A 2.5 V DC reference IC sup-
plies the reference voltage to the DACs. The DACs are con-
trolled by the processor over the SPI bus. The �5 V dynamic
range at the BNC of the input amplifier is converted to ap-
proximately �2.1 V at the comparator. This range must be
covered by the DAC. The voltage step from the DAC is ap-
proximately 1.2 mV, corresponding to 2.9 mV per step at the
BNC. Closed Case Calibration (CCC) is used for adjusting
the trigger levels. A known reference level is applied to the
BNC and the processor finds out the appropriate setting of the
DAC to match the reference level.
� Logic Level Conversion
The signals from the comparators must be converted from
ECL levels to LVPECL levels. There are three converter cir-
cuits. One for Channel A , one for Channel B and one for the
Set-Reset channel. The two main channels are fed to a Set-Re-
set flip-flop to make one-channel measurements with variable
hysteresis possible. There is also a converter for the signal
from an optional prescaler. It has PECL levels (+4.1 V and
+3.4 V) that are converted to LVTTL levels (+2.4 V and 0 V).
Oscillator Circuits
The processor has an 11.2896 MHz crystal. An internal PLL
in the processor uses the signal to make the internal processor
clock, approximately 50.8 MHz. The USB IC has a 6 MHz
crystal to make an internal clock and the GPIB IC has a 40
MHz crystal to make an internal clock.
The measurement reference oscillator (timebase) for the
timer/counter is a 10 MHz crystal oscillator or an optional
oven-controlled crystal oscillator (OCXO). Only one of these
is mounted. The user can also select an external reference sig-
nal, connected to the External Reference Input BNC on the
rear panel.
The standard oscillator consists of an inverter and a crystal.
The processor controls the frequency of the oscillator with a
PWM signal. The PWM signal is filtered to a DC level that
controls the capacitance of a capacitance diode. The varying
capacitance changes the frequency of the oscillator. The stan-
dard oscillator is adjusted with Closed Case Calibration. Ap-
ply a 10 MHz reference signal to Input A. The processor will
find the correct PWM signal to make the internal reference
frequency equal to the external reference frequency.
The optional oven-controlled oscillator is a complete oscilla-
tor in a small hermetic metal box. An internal accurate DC
voltage is available for use as a reference for a 12-bit DAC.
The filtered output voltage from the DAC sets the frequency
of the oven oscillator. The processor controls the DAC via the
SPI bus. The same Closed Case Calibration as for the stan-
dard oscillator is used. The oven oscillator is kept warm if the
line power is connected to the timer/counter, even if it is
switched off (in standby mode).

The 10 MHz reference signal is multiplied in a PLL to
100 MHz. The 100 MHz signal is used in the measuring logic
as a reference. The processor controls the PLL IC with the SPI
bus. A 100 MHz LC oscillator is used as the controlled ele-
ment where part of the C is a variable capacitance diode. Its
capacitance is controlled with a DC voltage from the PLL IC,
thus changing the frequency. The 10 MHz reference signal is
applied to the PLL IC as its reference and the 100 MHz output
frequency is exactly 10 times the reference frequency.
External Reference Input
A 1, 2, 5 or 10 MHz reference signal can be connected to the
rear panel BNC. After amplification in an operational ampli-
fier narrow pulses are made in two D flip-flops, one narrow
pulse for each input cycle. These pulses are fed to the 10 MHz
crystal filter. After the filter a reconstructed 10 MHz signal is
available. A variable capacitor is used for adjusting the filter.
Internal Reference Output
The selected 10 MHz reference signal (standard/oven oscilla-
tor or external reference) is available on the rear panel. The 10
MHz reference signal that is used internally by the dedicated
counter circuit (FPGA) logic is also sent to an output pin on
the FPGA. It is filtered to a sine wave and amplified in an out-
put buffer stage having 50 � drive capability.
Measuring Logic
The measuring logic consists of an FPGA, four interpolators
and an external control input on the rear panel. The FPGA
core uses +1.8 V supply voltage and the I/Os use +3.3 V sup-
ply voltage.
The FPGA is controlled by the processor over a 32-bit micro-
processor bus. Input signals (A, B, prescaler etc) and refer-
ence clock (internal 10 MHz oscillator or external reference)
are selected inside the FPGA. The logic for all measuring
functions and support functions (trigger indicators, start de-
lay, pacing etc) are inside the FPGA. A 100 MHz reference
clock is generated by a PLL circuit giving 10 ns basic mea-
surement resolution. To increase the measurement resolution
further, external interpolators are used. The measuring logic
also controls three LEDs on the display board; a GATE LED
indicating that a measurement is in progress, and two trigger
indicators telling that the comparators are triggering on the in-
put signals.
The four external interpolators are identical. Depending on
the selected measurement function 0, 2, 3 or 4 interpolators
are used. A pulse representing the time from an event on the
input to the following rising edge of the 100 MHz reference is
fed to the interpolator. During the pulse time a constant cur-
rent is charging a capacitor. The voltage on the capacitor is
measured with a 10-bit ADC. The capacitor is discharged and
the interpolator is ready for a new measurement.
An external control input BNC is located on the rear panel. A
signal applied to this connector can be used for controlling the
start of a measurement, for instance. A comparator converts
the analog input signal to a logic signal.
Processor Circuits
The processor is a Sharp LH79524. It contains an ARM7 core
and peripherals. It runs on a 50.8 MHz internal clock. The
processor that uses 3.3 V supply voltage has an internal circuit
that generates 1.8 V for the core. The I/Os use 3.3 V.
The 32-bit microprocessor bus communicates with a 16-bit
8 MByte flash memory and a 32-bit 32 MByte SDRAM. The
flash memory contains the program, data for loading the
FPGA, and stored data (calibration data etc.). At power-up the
code is copied from the flash to the SDRAM for faster execu-
tion.
Buffers isolate the memory part of the microprocessor bus
from the rest of the bus. Outside the buffers are the FPGA, the
GPIB interface and the USB interface.
The processor has a JTAG interface with a connector on the
circuit board.
A reset IC monitors the two main logic supply voltages,
+3.3 V and + 1.8 V. If a supply voltage fails, the processor will
be reset.
Two other buses are also used, an SPI bus and an I2C bus. The
SPI bus is an output only bus and the processor controls the
100 MHz PLL, the trigger level DACs, and the DAC for the
optional oven oscillator. The I2C bus is bidirectional and used
for communication with the temperature measurement IC, the
display board (keyboard + LCD), the prescaler (optional), and
the relays and filters in the input amplifier.
The temperature reading over the I2C bus is used for control-
ling the fan speed. A PWM output is utilized. The signal is fil-
tered and the resulting DC voltage controls the fan.
Another PWM output is used for controlling the frequency of
the standard crystal oscillator.
The LCD controller is a peripheral inside the processor. This
controller sends signals and data to the driver circuits in the
LCD on the display board.
The processor also controls the OFF switch. Only a signal
from the processor can switch off the power. The OFF button
on the front panel is read by the processor. ON is handled
without the processor, since it cannot respond to external
stimulus in standby mode.
Power Supply
This timer/counter has no primary power switch. If connected
to line power there are live parts inside the cabinet, and some
supply voltages are present on the main circuit board, even if
the secondary power switch on the front panel has been turned
off (standby mode).
4-16 Hardware Functional Description
A semi-protected AC/DC module is placed on spacers over
the main circuit board. It delivers three regulated DC voltages
to the counter, + 15 V, + 5 V and –15 V. When the counter is
connected to line power, these voltages are always present.
There is a + 5 V trimmer potentiometer on the AC/DC mod-
ule.
The ON/OFF circuit is active as soon as the counter is con-
nected to line power. The instrument automatically powers up
when line power is applied. Only the processor can switch the
circuit to OFF state (standby mode). Then only the power but-
ton on the front panel can switch the instrument to ON. Once
connected to line power and in OFF state (standby mode),
supply voltage +12 VU is distributed to the oven oscillator to
keep it warm. In standby mode a red LED is lit on the front
panel. To keep the AC/DC module stable in this mode, a
dummy load is connected to draw a quiescent current of 0.1 A
at +5 V.
The three main voltages are +15 V, +5 V and –15 V from the
AC/DC module. All other supply voltages are generated from
them and are, except for +12 VU to the oven oscillator,
switched off in standby mode.
Linear regulators are used for generating stable voltages with
low noise and without spikes. Some of them have a resistor
net at the input to dissipate part of the heat generated. Thus the
regulator itself will run cooler. The following voltages are
generated in this way:
+3.3 VA from +5 VU
-5.2 VA from -15 VU
-5.2 VI from -12 VA
-2.1 V from -12 VA
-12 VA from -15 VU
+12 VA from +15 VU
+12 VU from + 15 VU, to oven oscillator, not switched off in
standby mode
For digital and general use supply voltages are generated by
DC/DC converters:
+3.3 VD from +5 VU
+5 VD from +5 VU via a switch IC
+15 VD from +15 VU via a switch transistor
+1.8 V from +5 VU
Communication Interfaces
Both a GPIB and a USB interface are available for communi-
cation with external bus controllers. The connectors are lo-

The GPIB consists of an IC. Only 8 bits of the 32-bit micro-

processor (+3.3 V) and the GPIB circuit (+5 V), a buffer IC is
used for isolating the +5 V GPIB IC from the processor bus. A
40 MHz crystal is used for generating a local clock.
The USB consists of an IC. It communicates with the proces-
sor over the 32-bit microprocessor bus, but only 16 bits are
used. A 6 MHz crystal is used for generating a local clock.

condition the input signal so that the amplitude to the divider
is constant. The divider scales the input signal so that it can be
handled by the measuring logic on the main circuit board. A
detector switches off the output signal from the divider if the
input level is too low for the divider to work correctly (divid-
ers often oscillate without input signal).

Introduction
This chapter contains information about measures to be taken
for keeping the instrument in operative condition, or in other
words, what you can do to maintain the measurement accu-
racy, improve certain characteristics and prevent a break-
down.
Traditional troubleshooting is described in Chapter 6 - Repair.
Calibration
The single most important factor for maintaining the high per-
formance of your instrument is calibration on a regular basis.
A timer/counter is mainly used for time/frequency-related
measurements, so knowing the characteristics of your
timebase reference is vital to reliable results.
Scheduled calibration of the built-in timebase reference is
highly recommended in applications where external, more ac-
curate, frequency references are not available. Suitable cali-
bration intervals depend on the chosen timebase option and
the acceptable inaccuracy, but once a year is often a good
starting point.
The '90' has also limited voltage measurement capabilities,
and when these features are utilized, the voltage reference
should also be calibrated, preferably at the same time as the
frequency reference.
Both frequency and voltage calibration can be performed
without removing the cover, and the procedures are described
in Chapter 7, where you can also find information about cal-
culating calibration intervals for different timebase refer-
ences.
Instructions for FirmwareUpgrade
The firmware is stored in a FLASH PROM, so it is possible to
upgrade via one of the standard instrument interfaces (GPIB
or USB) without opening the case. USB is standard on most
PCs, but GPIB communication requires a special controller
board and dedicated SW from NI or CEC. A 'readme.txt' file
contains information not covered by these instructions. The
relevant files are available through the service organization.
– Make sure the National Instruments NI-VISA 3.2 or
later is installed with USB support, even though you are
going to use the GPIB interface for the upgrade.
– Establish a communication link between your PC and
the instrument over GPIB or USB by using a dedicated
application program, for instance NIMax from National
Instruments. No other instruments should be connected
to the same bus. Firmware upgrade over USB works
with firmware version V1.07 or above installed in the
instrument.
– Send *IDN? to the instrument and watch the response.
If the ID string is OK you can exit the communication
program and start the upgrading procedure.
– Download the latest firmware file (example name:
CNT_90_109_csl.hex) and the latest loader SW (exam-
ple name: Loader.exe) to a common directory on your
PC.
– Start the Loader.exe program.
– Press "Load" to open the firmware file. Follow the in-
structions on screen. The update is automatic, and pro-
cess information can be seen on the PC screen as well as
on the instrument display. Do not interrupt the process
too early as it may take between a few minutes up to an
hour, mostly depending on different possible hardware
combinations. A thermometer indicator on the PC moni-
tor gives status reports. The crucial part of the process is
when the message "FLASH updating (uninterruptible)"
is displayed. Do not under any circumstances interrupt
the loader while this message is visible. If the process
fails during this part, it may be impossible to control the
instrument from the bus as well as from the front panel.
Then you have to load new firmware over the JTAG
connection to the processor, a method that only the fac-
tory can apply.
– After a successful update, the counter is reset (if previ-
ous firmware is V1.01 and above). The message "Firm-
ware update complete. Loader is trying to connect to the
counter again" is displayed on the PC monitor. Confirm
by pressing OK.
– Press OK again when the message "Counter found" is
displayed.
– Press EXIT to leave the loader program.
– If the counter is not reset by the Loader program, turn
the counter off and on when the update is complete.
NOTE 1: With some firmware revisions and GPIB cards the
Loader gives an error message:
"Counter I/O error. Loader shutting down" after the
successful update. This is a loader fault and does not
harm the upgrade process.
– To remove the SRQ indicator on the front panel, which
might be present in such cases, start a GPIB communi-
cation tool and send the command "*PSC 1" and run a
full power cycle (OFF/ON).
NOTE 2: Some firmware revisions need a full power cycle to
resume proper operation. If the instrument does not
measure correctly after firmware upgrade, turn the in-
strument OFF and ON to initialize the hardware prop-
erly.
– After the update, enter the calibration menu (password
62951413) and run "Calibrate internals".
5-2 Introduction
Utility Program
Purpose
This service tool is used for configuring the timer/counter,
whenever information stored in firmware about serial number
and oscillator type etc. has been lost, for example after re-
placement of the main PCB. It is also used for defining a new
factory calibration.
Availability and System Requirements
The utility program can be obtained from the manufacturer or
your local service organization free of charge and can be run
on any PC with Windows 2K or XP equipped with a GPIB in-
terface from National Instruments. It is distributed as a com-
pressed file called PM6690.zip containing all the necessary
installation and data files including a readme.txt file with ad-
ditional information.
Installation
– Unpack the zip file in an empty directory by using
Winzip.
– Delete the original zip file if you want to save memory
space.
– Run the setup.exe program and follow the on-screen in-
structions.
Running the Application
After installation you can start the utility application by run-
ning the program PM6690 Utility.exe from the chosen direc-
tory. Refer to the readme.txt file for closer information on top-
ics not covered by the application user interface.
Fan Replacement
This instrument is equipped with a speed-controlled fan as
standard to sustain the specified operating temperature range.
If your instrument is operating in a 24 h/day system, you
should replace the fan every second year to maintain maxi-
mum reliability. For part-time applications and where low am-
bient temperatures prevail, an extended service interval is ac-
ceptable.
Follow the instructions on page 3-3 to replace the fan.
Other Important Information
There are no batteries of any kind in this instrument, so in gen-
eral it is only necessary to remove the cover when the fan is to
be replaced, or when a real fault calls for traditional trouble-
shooting.

Troubleshooting
General
The '90' is a highly integrated Timer/Counter in which a dedi-
cated FPGA counter circuit handles the signal processing, and
a microcontroller does the postprocessing and supervising
jobs. A number of additional functional units support these
basic tasks, for instance power supply, reference oscillator,
wideband input amplifiers, comparators, memory (RAM &
ROM), digital/analog converters, etc.
The units are treated from a troubleshooting point of view in
this chapter, which means that units described earlier should
be considered faultless before troubleshooting on units de-
scribed later.
WARNING: Live parts and accessible termi-
nals which can be dangerous to life are
always exposed inside the unit when it is
connected to the line power. Use extreme
caution when handling, testing or adjust-
ing the counter.
Where to Start
After reading the safety instructions, continue with this
chapter for troubleshooting and repair instructions. When you
have fixed the instrument, always do the Safety Inspection
and Test after Repair, as described later in this Chapter. Then
do the checks in Chapter 2, Performance Check. Recalibrate if
required by following the adjustment instructions in Chapter
7, Calibration Adjustments.
Logic Levels
The '90' contains logic of different families. The levels of the
standard families are listed in Table 6-1. In addition to these
families there is also low-level logic requiring lower supply
voltages, e.g. +3.3 V, +2.5 V and +1.8 V.
Required Test Equipment
To be able to test the instrument properly using this manual
you will need the equipment listed in Table 2-1. The list con-
tains the critical parameter specifications.
Operating Conditions
Power voltage must be between 90 VAC and 260 VAC. The in-
strument adapts automatically to the applied voltage.
Basic Functional Units
These are the units that are described in this chapter with ref-
erence to the page where the section starts:
• Power Supply (p. 6-4)
• Input Amplifiers (p. 6-8)
• Timebase Reference Circuits (p. 6-12)
• Prescalers (p.6-15)
• Microprocessor & Memories (p. 6-15)
• Microprocessor Bus & Interfaces (p. 6-21)
• Measurement Logic (p. 6-27)
Power Supply
The DC voltages needed in the instrument are generated from
the three main voltages of the AC/DC module.
The instrument has only a secondary power switch, i.e. the
AC/DC module is always operating if line power is applied.
The three output DC voltages (+5 V, +15 V, -15 V) from the
module are present on the main circuit board. When switched
off, the instrument is in the standby mode. In this mode only

the ON/OFF circuitry and the optional oven oscillator are
powered.
The AC/DC module should not be repaired. Not even the
built-in fuse should be replaced. Built-in circuits protect
against external overloads, so a blown fuse indicates that a se-
vere internal fault has occurred. Replace the complete module
instead.
Test the AC/DC module by measuring the three DC voltages
in TP9 (+5.1 ± 0.05 V), TP21 (-15 ± 1 V) and TP26
(+15 ± 1 V) on the main circuit board. See Figure 6-2. Note
that there is a +5 V trimmer on the module. If the +5 V is not
correct, disconnect the cable to J17 on the main circuit board.
Put a 47 � 1 W resistor on the connector according to Fig-
ure 6-2. Measure on the connector +5.1 ± 0.05 V, +15 ± 1 V
and -15 ± 1 V.
It can be difficult to measure the resistance in the supply con-
nector J17 on the main circuit board, because charges are kept
by capacitors some time after line power is removed. Remove
the cable from the AC/DC module. The resistance between
+5 V and ground should be approximately 700 �. See Fig-
ure 6-2. In a timer/counter with all capacitors uncharged, +15
V and -15 V should be at least M�.
Another way to test J17 is to connect 3 DC voltages from a
separate bench power supply directly to J17 (suitable connec-
tor MOLEX 09-91-0600). See Figure 6-2. The currents drawn
from the different supply voltages depend on options in-
stalled. Before making this measurement, you should remove
any prescaler option.
A timer/counter without options gives the following typical
results:
+5 V 0.7 A
+15 V 0.25 A
- 15 V 0.4 A
The oven oscillator increases the + 15 V current between
0.35 A (cold) and 0.1 A (warm).
A block diagram of the secondary power supply is shown in
Figure 6-1. All secondary voltages are switched off in standby
mode except +12 VU for the optional oven oscillator.
The ON/OFF circuitry controls the ON and OFF of the sec-
ondary voltages. Its own supply voltage is always ON, as long
as the instrument is connected to line power. See Figure 6-6.

Figure 6-2 Dummy load connection.
On connection of line power, R478 and C389 keep the
RESETN input of the flip-flop U29 low. This sets the QN out-
put of U29 high. Via Q47 (output signal low) and Q58 (output
signal high) the secondary power supply will be set in ON
mode. To switch to the standby mode, the processor sets the
SETN input of U29 low. This results in the QN output being
low and the secondary power supply being set to standby
mode via Q47 (output signal high) and Q58 (output signal
low). In standby mode a bleeder circuit on +5 VU is
connected. It draws approximately 100 mA to stabilize the
AC/DC module. The standby LED on the front panel is
switched on. To switch to ON mode from standby mode, a
negative pulse, generated by pressing the ON/OFF key on the
front panel, is connected to the RESETN input of U29.
Linear regulators are used for some voltages to ensure mini-
mum noise. Check the TPs below:
TP12: +3.3 VA (from +5 VU)
TP8: -5.2 VA (from -15 VU)
TP10: -12 VA (from -15 VU)
TP62: -5.2 VI (from -12 VA)
TP25: -2.1 V (from -12 VA)
TP16: +12 VA (from +15 VD)
TP17: +12 VU (from +15 VU) (to oven oscillator, not
switched off in standby mode)
For digital and general use some voltages are generated by
DC/DC converters. Check the following TPs:
TP14: +3.3 VD (from +5 VU)
TP1: +2.5 V (from +5 VU)
TP2: +1.8 V (from +5 VU)
Some voltages derived directly from the AC/DC module are
used as secondary supply voltages without further regulation,
and they have semiconductor switches in series to make it
possible to shut them off in standby mode. Check the TPs be-
low:
TP15: +15 VD (from +15 VU)
TP11: +5 VD (from +5 VU)
TP13: +5 VA (from +5 VD)
These 13 secondary voltages are used all over the instrument.
All secondary supply voltage lines are segmented into
branches with ferrite beads. See the schematics. This makes it
easier to isolate short circuits by removing ferrite beads tem-
porarily.

Fan Control
The fan is connected to +15 VU over a speed control circuit. It
is only ON if a control signal from the processor is present.
The first 8 minutes after power-up the fan will run at a fixed
speed, fed with +8.3 V. After that the fan is temperature con-
trolled. The processor reads the temperature from U39 via the
I2C bus. Depending on the temperature, the fan is fed with a
DC voltage between 8 and 13.5 V. The processor uses a PWM
signal that is filtered to control the fan.

Input Amplifiers
The input amplifiers for Channel A and Channel B are identi-
cal. A trigger level circuit belongs to each amplifier. The trig-
ger level is adjusted to match the hardware during the voltage
calibration procedure, see Chapter 7. Note that the input am-
plifiers must be adjusted according to Chapter 7 (step re-
sponse, sensitivity etc). The description refers to both chan-
nels (Channel B information within parentheses).
Recall the timer/counter default setting. Select the measure-
ment function Time A-B. Set both input channels to DC, Man
Trig = 0.000 V. No signals connected.
The RF shield must be removed before measuring on the input
amplifiers. It is soldered to two of the shield clips. Don't forget
to put the shield back afterwards and secure it by resoldering.
First measure some DC values. U3 pin 9 (pin 13) should be
near 0.000 V. The same applies to the trigger level, U3 pin 10
(pin 12). The voltage to ground at the point where R171
(R243) and R172 (R244) are connected should be approxi-
mately -0.8 V.
Connect a 1 kHz square wave with amplitude 1 Vpp in 1 M� to
Input A (Input B). Measure at the following points (see also
figure cc) and use the ground pads that are distributed over the
PC board:
Test Points Approximate Voltage
R140 to R141 (R212 to R213) 1.00 Vpp
R156 to C109 (R229 to C140) 0.40 Vpp

R301 both sides (R304 both sides) LVPECL levels 1.6 V and
2.6 V
Test the trigger level by manually setting the following trigger
levels. Check the voltage at X6 (X7) and U3 pin 10 (pin 12).
Set Level Approximate Voltage
+1 V +0.41 V
+4 V +1.65 V
-4 V -1.65 V
-1 V -0.41 V
Set the timer/counter to default. Select the measuring function
single period. Connect the 1 kHz square wave to channel A
(B). Measure with oscilloscope at X6 (X7). See figure dd for a
typical signal.
If any repair work has been done on the input amplifiers, both
adjustment and voltage calibration must be performed after-
wards. If any repair work has been done on the trigger level
circuits, at least voltage calibration must be performed after-
wards. See Chapter 7.

Timebase ReferenceCircuits
The measurement reference is either a 10 MHz signal from an
internal oscillator (standard crystal oscillator or optional
oven-controlled crystal oscillator) on the main circuit board or
a signal from the external reference input that accepts the fol-
lowing frequencies: 1, 5 and 10 MHz. A frequency multiplier
transforms the external signal to 10 MHz. The selected 10
MHz reference is always available at the internal reference
output. See Figure 6-14.
The main PCB is prepared for both types of internal timebase,
but only one of them is mounted. The selection is made at the
factory. You have to run the utility program (see page 5-3), if
the oscillator is to be changed. Closed Case Calibration is
used for adjusting the oscillator. On power-up the processor
outputs the setting that is stored as the correct one for
10.000000 MHz. It will take some time for the oven oscillator
to reach the correct frequency. A calibration must be
performed if the adjusting voltage should move during opera-
tion, not only on power-up.
The selection between the on board oscillator and the external
reference is made in the FPGA. The 10 MHz signal from the
other source is switched off.
Connect a 10 MHz signal to the external reference input. Use
the SETTINGS menu to alternate between internal and exter-
nal oscillator. Check for correct signals at U4:6 for the stan-
dard oscillator, at U4:8 for ther oven oscillator and at U33:3
for the external reference. Check also that the selected
timebase reference is present at the internal reference output
BNC connector on the rear panel.
Standard Oscillator
See Figure 6-14 and Figure 6-16.
The control signal (U4:1) must be high. The frequency is con-
trolled by a PWM signal from the processor. After filtering
the resulting DC voltage changes the capacitance of D24. A
DC level between 0 V and +3.3 V at R289 should somewhere
within the adjustment range give 10.000000 MHz. Check the
output signal and frequency at U4:6.
If the standard oscillator is repaired, a new calibration must be
performed. See Chapter 7. A new factory calibration by
means of the utility program should also be performed.
Optional Oven Oscillator
See Figure 6-14, Figure 6-15 and Figure 6-16.
The oven oscillator is a self-contained unit, enclosed in a
metal box and soldered to the main circuit board. It cannot be
repaired and must be replaced with a new oscillator if it is
faulty.
Let the oven oscillator warm up 10 minutes before starting
measurements. The 12 V supply voltage can be checked at
6-12 Troubleshooting
Figure 6-13 Oscillogram showing the signal at X7, Period Single B.
X17. The oven oscillator should be powered also in standby
mode.
The oven oscillator outputs a 10 MHz signal if powered. It
should be 1.3 Vpp measured at R282. If not selected, a gate
(U4) stops the signal, the control signal (U4:9) is then low.
The frequency is controlled by a DAC (U5). Its reference
voltage is derived from the oscillator, approximately +5 V
(C174). The polarity of the reference voltage is reversed in an
op amp (U6), and the voltage at U5:1 should be -5 V. The out-
put voltage from the DAC should be between 0 and Vref, mea-
sured at R281. The DAC is controlled by the processor via the
SPI bus.
The frequency adjustment range should be wide enough to al-
low for more than 10 years of oscillator aging. The oscillator
must be replaced if the normal control voltage range cannot
make the oscillator output 10.000000 MHz.
As a last resort to exclude external causes of malfunction,
desolder the oven oscillator from the main circuit board.
Place it upside down and connect +12 V and ground accord-
ing to Figure x. A cold oven oscillator draws approximately
0.30 - 0.35 A. During heating the current consumption varies.
After 10 minutes it should stabilize on less than 0.1 A. The
output Vref should be approximately +5 V and the 10 MHz
sinewave output signal should have an amplitude of more
than 2.5 Vpp measured with a 1 M�, 10x probe. The control
input has an internal bias to keep the output frequency in the
middle of the range. Adjust the control voltage between 0 V
and +5 V and check the output frequency range with a fre-
quency counter. The minimum trimming range should be
±5 Hz. 10.000000 MHz must be reached somewhere between
0 V and +5 V.
If the oven oscillator circuitry is repaired, a new calibration
must be performed. See Chapter 7. A new factory calibration
by means of the utility program should also be performed.
External Reference Input
See Figure 6-14 and Figure 6-17.
The input signal is amplified in U31. The output signal from
the amplifier should be a square wave with logic levels, repro-
ducing the timing characteristics of the input signal. Check
the signal at U32:11. U32 generates a short pulse (approxi-
mately 40 ns) for each input cycle, check at U32:9. These
pulses generate a broad spectrum of harmonics, and the
following high-Q 10 MHz crystal filter allows only a 10 MHz
sinewave to pass. Measure at X19. Note that the trimmer
C442 is used for maximizing the amplitude at X19. Check that
the amplitude is not less than 1 Vpp. If external reference is not
selected, the gate U33 stops the 10 MHz signal. The control
signal on U33:1 is then low.
100 MHz Multiplier
See Figure 6-14 and Figure 6-16.
100 MHz is used in the measuring logic, mainly as a reference
clock, but also for other purposes. A PLL is used for multi-
plying the 10 MHz reference to 100 MHz. On power-up the
processor sets up the PLL IC (U9) via the SPI bus. An output
signal, PLL LOCK, tells the processor if the loop is locked
(high level). A VCO, consisting of an inverter (U47) and an
LC circuit in the feedback loop, is controlled by the PLL IC.
The DC voltage from U9:2 is filtered and controls a capaci-
tance diode. The VCO frequency changes with the capaci-
tance. The loop can handle the switching of 10 MHz refer-
ence, from internal to external and vice versa. There is no
need for a new setup. If external reference is selected and no
such signal is connected to the instrument, the PLL will be un-

cal range of the VCO is 95 to 105 MHz, thus giving an error of
typically 5 % in the measuring results.
Check the loop voltage (DC) at R272. It should be 1.6 - 2.2 V.
Check the 100 MHz signal at U48:4. It should be locked to the
incoming 10 MHz at U9:8. Check the lock condition with a
2-channel oscilloscope. Trigger on the 10 MHz channel. Then
the signal on the other channel shall be fixed, i.e. not moving
along the time axis. Check the PLL LOCK signal at U9:14
(lock is high).
Prescalers
The optional prescalers are not to be repaired. The faulty unit
should be sent to the factory, and an exchange unit will be
returned.
The best way to isolate the fault is to use another, functioning,
timer/counter with the same prescaler. Interchange the
prescalers and see if the problem follows the prescaler or the
timer/counter.
First measure with Channels A and B and check that the result
is OK. Select the function Frequency C. Connect a signal ac-
cording to Table 6-2 to Input C. Check the following pins on
the prescaler connector J15 on the main circuit board.

Measure with oscilloscope and probe at pin 4. The output fre-

the table. Check with a frequency counter.
Note: The 3 GHz option has a sensitivity trimmer. See page
7-14 for information on how to adjust it.
Microprocessor & Memories
Startup Process
The processor in this instrument is a 32-bit ARM7TDMI. It is
housed in an IC (U13) together with peripheral units (SRAM,
timers, I2C bus interface, SPI bus interface, LCD controller
etc). The complete IC is a Triscend design and of type A7S20.
A separate memory bus on the processor is connected to one
16-bit Flash PROM (U17) and two 16-bit SDRAMs (U16 and
U15). The two SDRAMs are connected to form a 32-bit wide
memory.
A Reset IC (U116) monitors +3.3 VD, +2.5 V and +1.8V. The
reset signal is active low and kept low for approximately 160
to 180 ms after the voltages are OK. Measure at X33. The
ramp-up time for +3.3 VD is approximately 2 ms, for 2.5 V
approximately 4 ms and for 1.8 V approximately 3 ms.
The rising edge of the reset signal marks the start of the boot
sequence. All I/Os on the processor are set high with a weak
(high-ohmic) pull-up. The fan will run at full speed (R492).
The memory controller in the processor is set up. The proces-
sor reads in the Flash PROM for the initialization data at cer-
tain addresses. Check CE0 at U13 pin 16. When the data is
found, the processor loads it inside the processor IC. The I/Os
will be set up. The fan will stop running because the pin is set
low. The 32 kHz oscillator will start running (check at R357)
and an internal PLL will generate 30 MHz internal and exter-
nal clock, check X29.
After the initialization the processor starts executing code
from address 0 in the Flash PROM. The program copies the
code from the Flash PROM to the SDRAM. When done it
starts executing from the SDRAM. Check SDCE0 at U13:26.
The Flash is not used for executing code after this, only occa-
sionally for storing data that should be non-volatile.
See Figure 6-21 to Figure 6-23 for a survey of a typical instru-
ment startup.
The LCD is switched on. The LCD controller in the processor
generates the control signals for the LCD. See Figure 6-24 to
Figure 6-29. Note the different timing for the signals. The I2C
bus is used for switching the LCD on. The ON signal can be
checked at R34 on the display board. It should be high. The
LCD voltages must also be switched on. It is done by a control
signal from the processor. Check the signal at R33 on the dis-
play board. It should be high. Negative pulses on this signal
are used for adjusting the contrast of the LCD, i.e. the LCD
voltages. The range is 14.9 V to 17.5 V measured at X1 on the
display board. Set the contrast so X1 is 16.2 V. Check the
LCD voltages at X2 (14.7 V), X3 (13.3 V), X4 (2.9 V) and X5
(1.5 V). See Figure 6-19.
The FPGA (U11) has to be programmed. The I2C bus is used
for controlling the loading of the FPGA, the pins PROGN
(U40:9) INITN (U40:7) and DONE (U40:8) are used. The
clock (U11:155) and data (U11:153) are controlled by the

processor. See Figure 6-22. The loading starts when PROGN
is set low. The FPGA responds with a negative pulse on
INITN and setting DONE low. After loading 1442016 bits,
which takes approximately 2.2 s, the FPGAsets DONE high if
the loading was successful. If an error is detected, INITN is
set low. One clock pulse after DONE is set high all I/Os on the
FPGA are defined. If the loading of the FPGA is not success-
ful, the program just goes on with the rest of the startup
procedure.
The fan is set to 8.4 V. See Figure 6-23. Measure on J19 or
J28. The input amplifiers are initialized and a "click" from the
relays is heard. The I2C bus is used for controlling the relays.
Note: The I2C bus is of the utmost importance for the start of
the instrument. The FPGA, the LCD and the relays in
the input amplifiers all need a faultless I2C bus to work
properly.
Note: If the Flash PROM is exchanged, it must be replaced
by a preprogrammed Flash PROM. Voltage and
timebase calibration must be performed anew. The
utility program must be used for transferring the cali-
bration results to new factory calibrations. The serial
number and the oscillator option must also be pro-
grammed by the utility program.
The fan is kept at +8.4 V for the first 8.3 minutes. After that
the fan is temperature controlled. The processor reads the
temperature via the I2C bus every 10th second. IC U39 mea-
sures the temperature.
The keys on the display board are read over the I2C bus. If a
key is pressed, the I2C bus circuit U3 notices that and sends an
interrupt to the processor. Check at J13:9; low is interrupt.
The processor then scans the keys via the I2C bus to find the
depressed key. See Figure 6-30. During the scanning there
may appear some extra interrupts. This is not an error condi-
tion.

Microprocessor Bus &Interfaces
The instrument has a conventional 16-bit microprocessor bus
with 16 bits bidirectional data signals, 5 bits address signals,
Chip Selects and wrn and rdn signals. It connects the proces-
sor to the FPGA, the GPIB and the USB. See Figure 6-34.
The FPGA connection has 16 data bits, 5 address bits, chip
select, wrn and rdn. The FPGA is controlled by the processor
via the bus. Measuring functions are selected, for instance.
The FPGA is controlled between each measurement or block
of measurements. An interrupt signal from the FPGA is con-
nected to the processor. See Figure 6-36 for a typical timing
diagram.
The connection to the USB has 16 data bits, 1 address bit, chip
select, wrn and rdn. An interrupt signal from the USB IC is
connected to the processor. See Figure 6-38 for a typical tim-
ing diagram. The USB IC is a complete USB unit. It is not
powered from the USB bus. The USB IC (U34) has a 6 MHz
oscillator. Check at C416.
The connection to the GPIB has 8 bits, 5 address bits, chip se-
lect, wrn, rdn and a special control signal for the level shifting
IC (U38). U38 is a buffer between the logic level of +3.3 V for
the processor and the logic level of +5 V for the GPIB IC
(U37). An interrupt signal from the GPIB IC is connected to
the processor. See figure ee for a typical timing diagram. The
GPIB IC is a complete GPIB unit. The GPIB IC (U37) has a
40 MHz oscillator. Check at TP20.
Only the selected interface is involved in communication on
the microprocessor bus.

Since both interfaces consist of only one IC each, trouble-
shooting is fairly simple. Check that the oscillator (40 MHz or
6 MHz) is running. Check that the processor communicates
with the selected IC. Make sure the external controller (GPIB
or USB) and the interconnection cable used are OK.
There is a separate bus for transfer of the measurement result
data from the FPGA to the processor. This bus is 32 bits wide
and has a clock of its own, FCLK (U11:101). A signal from
the processor, FEMPTY (X28), indicates to the FPGA that a
new packet of 8 words of 32 bits can be transferred. This is
done with the FWR signal (X30) together with the FCLK. The
FPGA can call for attention via an interrupt request signal,
FFIQ (X31). This is done when the FPGA would like to trans-
fer a packet to the processor. See Figure 6-41 for a typical tim-
ing diagram.
Another bus from the microprocessor is the SPI bus. It is a se-
rial bus with one data signal and one clock signal that are com-
mon for all ICs connected to the bus. A separate load signal
for each IC controls the loading of the data. Connected to the
SPI bus are (See Figure 6-42 to Figure 6-45):
• The 100 MHz PLL IC (U9). The SPI bus is used onlyfor initialization after power on.
• The optional oven oscillator IC (U5). The SPI bus isused for initialization after power on and during atimebase calibration.
• The trigger levels IC (U46).
The last bus is the I2C bus. It is also a serial bus with two sig-
nals, SDA and SCL. Each connected IC has a unique address.
The message sent includes the address, and only the addressed
IC will listen to the message and respond by sending an ac-
knowledge to the master. Then it will react accordingly.
Introduction to the I2C Bus
The I2C bus is a 2-line serial bus for the communication be-
tween the ICs. The microprocessor controls the communica-
tion by means of the clock line SCL. One or more slaves can
read or write on the data line SDA.
The SDA and SCL are high at standby. All ICs connected to
the bus can sink SDA to low as they are interconnected via
open collector outputs. The microprocessor starts and stops
the communication by sending terms of start and stop:
During transmission the SDA can be changed only when the
SCL is low.
The microprocessor always begins to send the address infor-
mation. The format of this address information is seven ad-
dress bits, one read/write bit, and one acknowledge bit.
The addressed slave accepts by keeping the SDA line low
while the acknowledge bit (ACKN in ) is sent by the micro-
processor.
Example of addressing (address 30H):
The read/write bit R/W has the following meaning:
R/W = 1 means information from the slave to the µprocessor
R/W = 0 means information from the µprocessor to the slave.
The data information is sent after the address information.
The format of the data information is eight data bits followed
by one acknowledge bit. The reciever accepts by keeping the
SDAline low while the acknowledge bit (ACKN in ) is sent.
Example of data transmission (data 9BH):
The processor is the Master on the I2C bus. Slaves on the bus
are:
• The digital I/O IC U40 with address 20hex. It controlsthe loading of the FPGA at initialization after power on,it controls the relays and filters in the input amplifiers,and it reads the prescaler code at initialization afterpower on.
• The temperature measuring IC U39 with address48hex.
• The digital I/O IC U3 with address 21hex. It switchesthe LCD display on after power-on initialization, itscans the keyboard on the display circuit board.
The bus is connected to the prescaler connector J15 for future
use.

Measuring Logic
The measurements are made in the FPGA. Only four
interpolators are external to the FPGA. They increase the ba-
sic measurement resolution from 10 ns (100 MHz measure-
ment clock) to less than 100 ps. Different combinations of
interpolators are used for different measurement functions;
two, three or four in conjunction. The input signals come from
the input amplifiers. A, B and SR are differential LVPECL in-
puts. C, the prescaler input, is a single-ended LVTTL input.
The measuring logic also provides three LEDs on the front
panel with control signals.
The interpolator transforms a pulse width between 20 and
33 ns to a voltage. This voltage is read by an ADC. The
interpolator is calibrated by reference pulses having a width of
20 and 30 ns . The measurement pulse varies between 22 and
32 ns typically. The ADC has two reference voltages, the
lower limit and the upper limit. The interpolated voltage must
never fall outside these limits.
Select the default setting from the front panel. Apply a
10 MHz sinewave signal (stable low jitter signal) to input A.
The signal should be found at the pins of the FPGA. Check
that the measurement signal is present on pins 17 and 18 (dif-
ferential input) on the FPGA U11.The trigger indicator LED
A on the front panel should blink. The gate indicator on the
front panel should also blink and the display should show the
measurement result. In this setting the S/R flip-flop U12 is
used. Check that the measurement signal is present on pins 30
and 31 (differential input) on the FPGA U11.
Move the 10 MHz sinewave signal to input B. Change the
measurement function to Frequency B. Check that the mea-
surement signal is present on pins 20 and 21 (differential in-
put) on the FPGA U11. The trigger level LED B and the gate
indicator LED should blink and the display should show the
measurement result.
Move the 10 MHz sinewave signal back to input A. Change
the measurement function to Period Single A. Now the S/R
flip-flop should not be used, check the control signal at R623,
it should be -1.6 V (on is -1.0 V). Select statistics. The std de-
viation should be less than 100 ps.
Change the measurement function to Time Interval A - A. Se-
lect Statistics Mode. Check that the standard deviation is less
than 100 ps. Measure at pin 8 of the ADCs U23, U22, U21
and U20. Two types are current, ADC10461 and ADC1061.
See Figure 6-49 for a typical timing diagram with
ADC10461. Figure 6-50 shows an example with ADC1061.
Check the upper (TP3) and lower (TP4) voltage limits of the
ADCs. They should be approximately 3.5 - 3.6 V and 1.1 - 1.4
V. The important thing is that the lowest voltage pulse on any

pin 8 of the ADCs (U23, U22, U21, U20) should be at least
0.2 V above the lower limit and that the highest voltage pulse
on any pin 8 of the ADCs should be at least 0.3 V below the
upper limit. If an interpolator has a voltage pulse outside the
limits the measurement result will be wrong. Figure cc shows
the signals on an ADC.
The signal from the prescaler is connected to pin 22 (sin-
gle-ended) of U11. It comes via a level converter. Check the
input signal to the converter at R335 (PECL levels).
If the FPGA or a part in the interpolators has been changed or
repaired, a calibration of internals must be performed after-
wards. See Chapter 7.
Note The interpolator design has varied slightly in the
course of time, but the pulses in Figures 6-49 and
6-50 are very little affected.

Troubleshooting
General
The '90' is a highly integrated Timer/Counter in which a dedi-
cated FPGA counter circuit handles the signal processing, and
a microcontroller does the postprocessing and supervising
jobs. A number of additional functional units support these
basic tasks, for instance power supply, reference oscillator,
wideband input amplifiers, comparators, memory (RAM &
ROM), digital/analog converters, etc.
The units are treated from a troubleshooting point of view in
this chapter, which means that units described earlier should
be considered faultless before troubleshooting on units de-
scribed later.
WARNING: Live parts and accessible termi-
nals which can be dangerous to life are
always exposed inside the unit when it is
connected to the line power. Use extreme
caution when handling, testing or adjust-
ing the counter.
Where to Start
After reading the safety instructions, continue with this
chapter for troubleshooting and repair instructions. When you
have fixed the instrument, always do the Safety Inspection
and Test after Repair, as described later in this Chapter. Then
do the checks in Chapter 2, Performance Check. Recalibrate if
required by following the adjustment instructions in Chapter
7, Calibration Adjustments.
Logic Levels
The '90' contains logic of different families. The levels of the
standard families are listed in Table 6-3. In addition to these
families there is also low-level logic requiring lower supply
voltages, e.g. +3.3 V and +1.8 V.
Required Test Equipment
To be able to test the instrument properly using this manual
you will need the equipment listed in Table 2-1. The list con-
tains the critical parameter specifications.
Operating Conditions
Power voltage must be between 90 VAC and 260 VAC. The in-
strument adapts automatically to the applied voltage.
Basic Functional Units
These are the units that are described in this chapter with ref-
erence to the page where the section starts:
• Power Supply (p. 6-32)
• Input Amplifiers (p. 6-36)
• Timebase Reference Circuits (p. 6-40)
• Prescalers (p.6-43)
• Microprocessor & Memories (p. 6-43)
• Microprocessor Bus & Interfaces (p. 6-49)
• Measurement Logic (p. 6-55)
Power Supply
The DC voltages needed in the instrument are generated from
the three main voltages of the AC/DC module.
The instrument has only a secondary power switch, i.e. the
AC/DC module is always operating if line power is applied.
The three output DC voltages (+5 V, +15 V, -15 V) from the
module are present on the main circuit board. When switched
off, the instrument is in the standby mode. In this mode only

the ON/OFF circuitry and the optional oven oscillator are
powered.
The AC/DC module should not be repaired. Not even the
built-in fuse should be replaced. Built-in circuits protect
against external overloads, so a blown fuse indicates that a se-
vere internal fault has occurred. Replace the complete module
instead.
Test the AC/DC module by measuring the three DC voltages
in TP9 (+5.1 ± 0.05 V), TP21 (-15 ± 1 V) and TP26
(+15 ± 1 V) on the main circuit board. See Figure 6-55. Note
that there is a +5 V trimmer on the module. If the +5 V is not
correct, disconnect the cable to J17 on the main circuit board.
Put a 47 � 1 W resistor on the connector according to Figure
6-55. Measure on the connector +5.1 ± 0.05 V, +15 ± 1 V and
-15 ± 1 V.
It can be difficult to measure the resistance in the supply con-
nector J17 on the main circuit board, because charges are kept
by capacitors some time after line power is removed. Remove
the cable from the AC/DC module. The resistance between
+5 V and ground should be approximately 700 �. See Figure
6-55. In a timer/counter with all capacitors uncharged, +15 V
and -15 V should be >1 M�.
Another way to test J17 is to connect 3 DC voltages from a
separate bench power supply directly to J17 (suitable connec-
tor MOLEX 09-91-0600). See Figure 6-55. The currents
drawn from the different supply voltages depend on options
installed. Before making this measurement, you should re-
move any prescaler option.
A timer/counter without options gives the following typical
results:
+5 V 0.7 A
+15 V 0.3 A
- 15 V 0.4 A
The oven oscillator increases the + 15 V current between
0.35 A (cold) and 0.1 A (warm).
A block diagram of the secondary power supply is shown in
Figure 6-54. All secondary voltages are switched off in
standby mode except +12 VU for the optional oven oscillator.
The ON/OFF circuitry controls the ON and OFF of the sec-
ondary voltages. Its own supply voltage is always ON, as long
as the instrument is connected to line power. See Figure 6-59.

Figure 6-55 Dummy load connection.
On connection of line power, R478 and C389 keep the
RESETN input of the flip-flop U29 low. This sets the QN out-
put of U29 high. Via Q47 (output signal low) and Q58 (output
signal high) the secondary power supply will be set in ON
mode. To switch to the standby mode, the processor sets the
SETN input of U29 low. This results in the QN output being
low and the secondary power supply being set to standby
mode via Q47 (output signal high) and Q58 (output signal
low). In standby mode a bleeder circuit on +5 VU is
connected. It draws approximately 100 mA to stabilize the
AC/DC module. The standby LED on the front panel is
switched on. To switch to ON mode from standby mode, a
negative pulse, generated by pressing the ON/OFF key on the
front panel, is connected to the RESETN input of U29.
Linear regulators are used for some voltages to ensure mini-
mum noise. Check the TPs below:
X12: +3.3 VA (from +5 VU)
X8: -5.2 VA (from -15 VU)
X10: -12 VA (from -15 VU)
X62: -5.2 VI (from -12 VA)
X25: -2.1 V (from -12 VA)
X16: +12 VA (from +15 VD)
X17: +12 VU (from +15 VU) (to oven oscillator, not
switched off in standby mode)
For digital and general use some voltages are generated by
DC/DC converters. Check the following TPs:
X14: +3.3 VD (from +5 VU)
X2: +1.8 V (from +5 VU)
Some voltages derived directly from the AC/DC module are
used as secondary supply voltages without further regulation,
and they have semiconductor switches in series to make it
possible to shut them off in standby mode. Check the TPs be-
low:
X15: +15 VD (from +15 VU)
X11: +5 VD (from +5 VU)
X13: +5 VA (from +5 VD)
These 12 secondary voltages are used all over the instrument.
All secondary supply voltage lines are segmented into
branches with ferrite beads. See the schematics. This makes it
easier to isolate short circuits by removing ferrite beads tem-
porarily.
The microprocessor, U13, has an internal linear regulator that
generates +1.8 V from +3.3 V. This voltage is used by the pro-
cessor core and can be checked at X66.

Fan Control
The fan is connected to +15 VU over a speed control circuit. It
is only ON if a control signal from the processor is present.
The first 8 minutes after power-up the fan will run at a fixed
speed, fed with +8.3 V. After that the fan is temperature con-
trolled. The processor reads the temperature from U39 via the
I2C bus. Depending on the temperature, the fan is fed with a
DC voltage between 8 and 13.5 V. The processor uses a PWM
signal that is filtered to control the fan.

Figure 6-58 Important power supply locations #2.
Input Amplifiers
The input amplifiers for Channel A and Channel B are identi-
cal. A trigger level circuit belongs to each amplifier. The trig-
ger level is adjusted to match the hardware during the voltage
calibration procedure, see Chapter 7. Note that the input am-
plifiers must be adjusted according to Chapter 7 (step re-
sponse, sensitivity etc). The description refers to both chan-
nels (Channel B information within parentheses).
Recall the timer/counter default setting. Select the measure-
ment function Time A-B. Set both input channels to DC, Man
Trig = 0.000 V. No signals connected.
The RF shield must be removed before measuring on the input
amplifiers. It is soldered to two of the shield clips. Don't forget
to put the shield back afterwards and secure it by resoldering.
First measure some DC values. U3 pin 9 (pin 13) should be
near 0.000 V. The same applies to the trigger level, U3 pin 10
(pin 12). The voltage to ground at the point where R171
(R243) and R172 (R244) are connected should be approxi-
mately -0.8 V.
Connect a 1 kHz square wave with amplitude 1 Vpp in 1 M� to
Input A (Input B). Measure at the following points (see also
Figure 6-60) and use the ground pads that are distributed over
the PC board:
Test Points Approximate Voltage

R156 to C109 (R229 to C140) 0.40 Vpp

R301 both sides (R304 both sides) LVPECL levels 1.6 V and
2.6 V
Test the trigger level by manually setting the following trigger
levels. Check the voltage at X6 (X7) and U3 pin 10 (pin 12).
Set Level Approximate Voltage
+1 V +0.41 V
+4 V +1.65 V
-4 V -1.65 V
-1 V -0.41 V
Set the timer/counter to default. Select the measuring function
Single Period. Connect the 1 kHz square wave to channel A
(B). Measure with oscilloscope at X6 (X7). See Figure 6-65
(Figure 6-66) for a typical signal.
If any repair work has been done on the input amplifiers, both
adjustment and voltage calibration must be performed after-
wards. If any repair work has been done on the trigger level
circuits, at least voltage calibration must be performed after-
wards. See Chapter 7.

Timebase ReferenceCircuits
The measurement reference is either a 10 MHz signal from an
internal oven-controlled crystal oscillator on the main circuit
board or a signal from the external reference input that accepts
the following frequencies: 1, 5 and 10 MHz. Afrequency mul-
tiplier transforms the external signal to 10 MHz. The selected
10 MHz reference is always available at the internal reference
output. See Figure 6-67.
The main PCB is prepared for both types of internal timebase,
but only one of them is mounted. The selection is made at the
factory. You have to run the utility program if the oscillator is
to be changed. Closed Case Calibration is used to adjust the
oscillator. On power-up the processor outputs the setting that
is stored as the correct one for 10.000000 MHz. It will take
some time for the oven oscillator to reach the correct fre-
quency. A calibration must be performed if the adjusting volt-
age should move during operation, not only on power-up.
The selection between the on board oscillator and the external
reference is made in the FPGA. The 10 MHz signal from the
other source is switched off.
Connect a 10 MHz signal to the external reference input. Use
the SETTINGS menu to alternate between internal and exter-
nal oscillator. Check for correct signals at U4:6 for the stan-
dard oscillator, at U4:8 for the oven oscillator and at U33:3 for
the external reference. Check also that the selected timebase
reference is present at the internal reference output BNC con-
nector on the rear panel.
Oven Oscillator
See Figure 6-68 and Figure 6-69.
The oven oscillator is a self-contained unit, enclosed in a
metal box and soldered to the main circuit board. It cannot be
repaired and must be replaced with a new oscillator if it is
faulty.
Let the oven oscillator warm up 10 minutes before starting
measurements. The 12 V supply voltage can be checked at
X17. The oven oscillator should be powered also in standby
mode.
The oven oscillator outputs a 10 MHz signal if powered. It
should be 1.3 Vpp measured at R282. If not selected, a gate
(U4) stops the signal, the control signal (U4:9) is then low.
The frequency is controlled by a DAC (U5). Its reference
voltage is derived from the oscillator, approximately +5 V
(C174). The polarity of the reference voltage is reversed in an
op amp (U6), and the voltage at U5:1 should be -5 V. The out-
put voltage from the DAC should be between 0 and Vref, mea-
sured at R281. The DAC is controlled by the processor via the
SPI bus.
The frequency adjustment range should be wide enough to al-
low for more than 10 years of oscillator aging. The oscillator

Troubleshooting 6-41
must be replaced if the normal control voltage range cannot
make the oscillator output 10.000000 MHz.
As a last resort to exclude external causes of malfunction,
desolder the oven oscillator from the main circuit board.
Place it upside down and connect +12 V and ground accord-
ing to Figure 6-68. A cold oven oscillator draws approxi-
mately 0.30 - 0.35 A. During heating the current consumption
varies. After 10 minutes it should stabilize on less than 0.1 A.
The output Vref should be approximately +5 V and the 10
MHz sinewave output signal should have an amplitude of
more than 2.5 Vpp measured with a 1 M�, 10x probe. The
control input has an internal bias to keep the output frequency
in the middle of the range. Adjust the control voltage between
0 V and +5 V and check the output frequency range with a fre-
quency counter. The minimum trimming range should be
±5 Hz. 10.000000 MHz must be reached somewhere between
0 V and +5 V.
If the oven oscillator circuitry is repaired, a new calibration
must be performed. See Chapter 7. A new factory calibration
by means of the utility program should also be performed.
External Reference Input
See Figure 6-67 and Figure 6-70.
The input signal is amplified in U31. The output signal from
the amplifier should be a square wave with logic levels, repro-
ducing the timing characteristics of the input signal. Check
the signal at U32:11. U32 generates a short pulse (approxi-
mately 40 ns) for each input cycle, check at U32:9. These
pulses generate a broad spectrum of harmonics, and the
following high-Q 10 MHz crystal filter allows only a 10 MHz
sinewave to pass. Measure at X19. Note that the trimmer
C442 is used for maximizing the amplitude at X19. Check that
the amplitude is not less than 1 Vpp. If external reference is not
selected, the gate U33 stops the 10 MHz signal. The control
signal on U33:1 is then low.
100 MHz Multiplier
See Figure 6-67 and Figure 6-69.
100 MHz is used in the measuring logic, mainly as a reference
clock, but also for other purposes. A PLL is used for multi-
plying the 10 MHz reference to 100 MHz. On power-up the
processor sets up the PLL IC (U9) via the SPI bus. An output
signal, PLL LOCK, tells the processor if the loop is locked
(high level). A VCO, consisting of an inverter (U47) and an
LC circuit in the feedback loop, is controlled by the PLL IC.
The DC voltage from U9:2 is filtered and controls a capaci-
tance diode. The VCO frequency changes with the capaci-
tance. The loop can handle the switching of 10 MHz refer-
ence, from internal to external and vice versa. There is no
need for a new setup. If external reference is selected and no
such signal is connected to the instrument, the PLL will be un-

cal range of the VCO is 95 to 105 MHz, thus giving an error of
typically 5 % in the measuring results.
Check the loop voltage (DC) at R272. It should be 1.6 - 2.2 V.
Check the 100 MHz signal at U48:4. It should be locked to the
incoming 10 MHz at U9:8. Check the lock condition with a
2-channel oscilloscope. Trigger on the 10 MHz channel. Then
the signal on the other channel shall be fixed, i.e. not moving
along the time axis. Check the PLL LOCK signal at U9:14
(lock is high).
Prescaler
The optional prescalers are not to be repaired. The faulty unit
should be sent to the factory, and an exchange unit will be
returned.
The best way to isolate the fault is to use another, functioning,
timer/counter with the same prescaler. Interchange the
prescalers and see if the problem follows the prescaler or the
timer/counter.
First measure with Channels A and B and check that the result
is OK. Select the function Frequency C. Connect a signal ac-
cording to Table 6-2 to Input C. Check the following pins on
the prescaler connector J15 on the main circuit board.

Measure with oscilloscope and probe at pin 4. The output fre-
quency should be the input frequency divided by the factor in
the table. Check with a frequency counter.
Note: The 2.7 GHz option has a sensitivity trimmer. See
page 7-14 for information on how to adjust it.
Microprocessor & Memories
Startup Process
The processor in this instrument is a Sharp LH79524 with a
32-bit ARM720T core. It is housed in an IC (U13) together
with peripheral units like SRAM, timers, I2C bus interface,
SPI bus interface and LCD controller.
The 32-bit microprocessor bus is connected to one 16-bit
Flash PROM (U17) and two 16-bit SDRAMs (U15 & U16).
The two SDRAMs are organized as one 32-bit wide memory.
The microprocessor bus is also, via bidirectional buffers, con-
nected to an FPGA, a USB IC and a GPIB IC.
A reset IC (U116) monitors +3.3 VD and +1.8 V. The reset
signal is active low and is kept low for approximately 160 to
180 ms after the voltages have settled and been approved.
Measure at X33. The ramp-up time for +3.3 VD is approxi-
mately 3 ms.
The processor has an internal linear regulator that generates
the core voltage (+1.8 V) from the +3.3 VD I/O voltage.
Check +1.8 V at X66.
The rising edge of the reset signal marks the start of the boot
sequence. All I/Os on the processor are set to inputs. The
11.2896 MHz oscillator will start running (check at R358).
An internal PLL generates 1.88 MHz (reset value) as micro-
processor clock (check at X29). The processor will start read-
ing in the Flash PROM. The initializing of the processor and
the peripherals will start.
The I/Os will be set up, the processor clock will be set to
50.8 MHz (check at X29). The SDRAMs will start, and the
code is copied from the Flash PROM to the SDRAMs. From
now on the code is executed from the SDRAMs. Then all the
other subsystems are initialized: I2C bus, LCD controller, SPI
bus, fan etc. The FPGAis also programmed by the processor.
The progress of the initialization can be followed at two test
points, X55 and X31.

The LCD is switched on. The LCD controller in the processor
generates the control signals for the LCD. See Figures 6-77 to
6-81and 6-83. Note the different timing for the signals. The
I2C bus is used for switching the LCD on. The ON signal can
be checked at R34 on the display board. It should be high. The
LCD voltages must also be switched on. It is done by a control
signal from the processor. Check the signal at R33 on the dis-
play board. It should be high. Negative pulses on this signal
are used for adjusting the contrast of the LCD, i.e. the LCD

display board. Set the contrast so X1 is 16.2 V. Check the
LCD voltages at X2 (14.7 V), X3 (13.3 V), X4 (2.9 V) and X5
(1.5 V). See Figure 6-72.
The FPGA (U11) is programmed by the processor. The used
pins are PROGN, INITN, DONE (X65), Clock and Data. See
Figure 6-75. The loading starts when PROGN is set low. Then
the processor checks that INITN is low and sets PROGN high
again. The FPGA responds by setting DONE low. After load-
ing, which takes approximately 1.4 s, the FPGA sets DONE
high (check X65), if the loading was successful. If an error is
detected, INITN is set low. One clock pulse after DONE is set
high, all I/Os on the FPGA are defined. If the loading of the
FPGA is not successful, the program just goes on with the rest
of the startup procedure. At test point X67 the FPGA will out-
put approximately 14 Hz. This signal shows that the FPGA is
working and will be switched off about 8 minutes after
power-up.
The fan is set to 8.4 V. Measure on J19 or J28. The input am-
plifiers are initialized and a "click" from the relays is heard.
The I2C bus is used for controlling the relays.
Note: The I2C bus is of the utmost importance for the start of
the instrument. The keys, the LCD and the relays in
the input amplifiers all need a faultless I2C bus to work
properly.
Note: If the Flash PROM is exchanged, it must be replaced
by a preprogrammed Flash PROM. Voltage and
timebase calibration must be performed anew. The
utility program must be used for transferring the cali-
bration results to new factory calibrations. The serial
number and the oscillator option must also be pro-
grammed by the utility program.

The fan is kept at +8.4 V for the first 8.3 minutes. After that
the fan is temperature controlled. The processor reads the
temperature via the I2C bus every 10th second. IC U39 mea-
sures the temperature.
The keys on the display board are read over the I2C bus. If a
key is pressed, the I2C bus circuit U3 notices that and sends an
interrupt to the processor. Check at J13:9; low is interrupt.
The processor then scans the keys via the I2C bus to find the
depressed key. See Figure 6-82. During the scanning there
may appear some extra interrupts. This is not an error condi-
tion.
Microprocessor Bus &Interfaces
The microprocessor bus is divided into two parts with buffers.
The inner part consists of the Flash PROM and the SDRAMs.
Buffers isolate the inner part from long lines in order to make
the SDRAM work safely. The buffers of the 32-bit data bus
are bidirectional and a control signal opens the buffers only
during reads and writes (U56:8, low to open buffers). The di-
rection of the buffers is controlled by the rdn from the proces-
sor.
The outer part consists of the 32-bit data bus and the 5-bit ad-
dress bus. It connects the processor (U13) to the FPGA (U11),
the GPIB and the USB. See Figure 6-87.
The FPGA connection has 32 data bits, 5 address bits, chip se-
lect, wrn and rdn. The FPGAis controlled by the processor via
the bus; measurement functions are selected, for instance. The
FPGA is controlled between each measurement or block of
measurements. An interrupt signal from the FPGA is con-
nected to the processor. See Figure 6-89 for a typical timing
diagram.

LP
RESN

The connection to the USB has 16 data bits, 1 address bit, chip
select, wrn and rdn. An interrupt signal from the USB IC is
connected to the processor. See Figure 6-90 for a typical tim-
ing diagram. The USB IC is a complete USB unit. It is not
powered from the USB bus. The USB IC (U34) has a 6 MHz
oscillator. Check at C416.
The connection to the GPIB has 8 data bits, 5 address bits,
chip select, wrn, rdn and a special control signal for the level
shifting IC (U38). U38 is a buffer between the logic level of
+3.3 V for the processor and the logic level of +5 V for the
GPIB IC (U37). An interrupt signal from the GPIB IC is con-
nected to the processor. See Figure 6-91 for a typical timing
diagram. The GPIB IC is a complete GPIB unit. The GPIB IC
(U37) has a 40 MHz oscillator. Check at TP20.
Only the selected interface is involved in communication on
the microprocessor bus.
Since both interfaces consist of only one IC each, trouble-
shooting is fairly simple. Check that the oscillator (40 MHz or
6 MHz) is running. Check that the processor communicates
with the selected IC. Make sure the external controller (GPIB
or USB) and the interconnection cable used are OK.
The transfer of measurement results from the FPGA to the mi-
croprocessor goes via the 32-bit microprocessor bus and nor-
mal reads. There are some extra handshake pins to facilitate
the transfer. An interrupt signal is sent to the microprocessor if
results are to be read, ALERT, X30. X28 (EMPTY) indicates
that it is allowed to read results, and the microprocessor sets a
signal high to indicate that it is reading results, UPRD,
U11:203. Results are always read in packets of 8 words. See
Figure 6-92 for a typical timing diagram.
Another bus from the microprocessor is the SPI bus. It is a se-
rial bus with one data signal and one clock signal that are com-
mon to all ICs connected to the bus. A separate load signal for
each IC controls the loading of the data. Connected to the SPI
bus are (See Figure 6-93 to Figure 6-96):
• The 100 MHz PLL IC (U9). The SPI bus is used onlyfor initialization after power on.
• The optional oven oscillator IC (U5). The SPI bus isused for initialization after power on and during atimebase calibration.
• The trigger levels IC (U46).
The last bus is the I2C bus. It is also a serial bus with two sig-
nals, SDA and SCL. Each connected IC has a unique address.
The message sent includes the address, and only the addressed
IC will listen to the message and respond by sending an ac-

The I2C bus is a 2-line serial bus for the communication be-
tween the ICs. The microprocessor controls the communica-
tion by means of the clock line SCL. One or more slaves can
read or write on the data line SDA.
The SDA and SCL are high at standby. All ICs connected to
the bus can sink SDA to low as they are interconnected via
open collector outputs. The microprocessor starts and stops
the communication by sending terms of start and stop:
During transmission the SDA can be changed only when the
SCL is low.
The microprocessor always begins to send the address infor-
mation. The format of this address information is seven ad-
dress bits, one read/write bit, and one acknowledge bit.
The addressed slave accepts by keeping the SDA line low
while the acknowledge bit (ACKN in ) is sent by the micro-
processor.
Example of addressing (address 30H):
The read/write bit R/W has the following meaning:
R/W = 1 means information from the slave to the µprocessor
R/W = 0 means information from the µprocessor to the slave.
The data information is sent after the address information.
The format of the data information is eight data bits followed
by one acknowledge bit. The reciever accepts by keeping the
SDAline low while the acknowledge bit (ACKN in ) is sent.
Example of data transmission (data 9BH):

� The I2C Bus in the ‘90’
The processor is the Master on the I2C bus. Slaves on the bus
are:
• The digital I/O IC U40 with address 20hex. It controlsthe relays and filters in the input amplifiers.
• The temperature measuring IC U39 with address48hex.
• The digital I/O IC U3 with address 21hex. It switchesthe LCD display on after power-on initialization, itscans the keyboard on the display circuit board.
The bus is connected to the prescaler connector J15 for future
use.
See Figure 6-97 and Figure 6-98.
Measuring Logic
The measurements are made in the FPGA. Only four
interpolators are external to the FPGA. They increase the ba-
sic measurement resolution from 10 ns (100 MHz measure-
ment clock) to less than 100 ps. Different combinations of
interpolators are used for different measurement functions;
two, three or four in conjunction. The input signals come from
the input amplifiers. A, B and SR are differential LVPECL in-
puts. C, the prescaler input, is a single-ended LVTTL input.
The measuring logic also provides three LEDs on the front
panel with control signals.
The interpolator transforms a pulse width between 20 and
33 ns to a voltage. This voltage is read by an ADC. The
interpolator is calibrated by reference pulses having a width
of 20 and 30 ns . The measurement pulse varies between 22
and 32 ns typically. The ADC has two reference voltages, the
lower limit and the upper limit. The interpolated voltage must
never fall outside these limits.
Select the default setting from the front panel. Apply a
10 MHz sinewave signal (stable low jitter signal) to input A.
The signal should be found at the pins of the FPGA. Check
that the measurement signal is present on pins 10 and 11 (dif-
ferential input) on the FPGA U11.The trigger indicator LED
A on the front panel should blink. The gate indicator on the
front panel should also blink and the display should show the
measurement result. In this setting the S/R flip-flop U12 is
used. Check that the measurement signal is present on pins 45
and 46 (differential input) on the FPGA U11.
Move the 10 MHz sinewave signal to input B. Change the
measurement function to Frequency B. Check that the mea-
surement signal is present on pins 20 and 21 (differential in-
put) on the FPGA U11. The trigger level LED B and the gate
indicator LED should blink and the display should show the
measurement result.

Move the 10 MHz sinewave signal back to input A. Change
the measurement function to Period Single A. Now the S/R
flip-flop should not be used, check the control signal at R623,
it should be -1.6 V (on is -1.0 V). Select statistics. The std de-
viation should be less than 100 ps.
Change the measurement function to Time Interval A - A. Se-
lect Statistics Mode. Check that the standard deviation is less
than 100 ps. Measure at pin 8 of the ADCs U23, U22, U21 and
U20. See Figure 6-100 for a typical timing diagram. Check
the upper (TP3) and lower (TP4) voltage limits of the ADCs.
They should be approximately 3.5 - 3.6 V and 1.0 - 1.4 V. The
important thing is that the lowest voltage pulse on any pin 8 of
the ADCs (U23, U22, U21, U20) should be at least 0.2 V
above the lower limit and that the highest voltage pulse on any
pin 8 of the ADCs should be at least 0.3 V below the upper
limit. If an interpolator has a voltage pulse outside the limits
the measurement result will be wrong. Figure 6-101 shows the
signals on an ADC.
The signal from the prescaler is connected to pin 22 (sin-
gle-ended) of U11. It comes via a level converter. Check the
input signal to the converter at R335 (PECL levels).
If the FPGA or a part in the interpolators has been changed or
repaired, a calibration of internals must be performed after-
wards. See Chapter 7.

Safety Inspection and Test After Repair
General Directives
After repair in the primary circuits, make sure that you have
not reduced the creepage distances and clearances.
Before soldering, component pins must be bent on the solder
side of the board. Replace insulating guards and plates.
Safety Components
Components in the primary circuits are important to the safety
of the instrument and may only be replaced by components
obtained from your local service organization.
Check the Protective Ground Connection
Visually check the correct connection and condition and mea-
sure the resistance between the protective lead at the plug and
the cabinet. The resistance must not be more than 0.5 �. Dur-
ing measurement, the power cord should be moved. Any vari-
ations in resistance shows a defect.
Safety Inspection and Test After Repair 6-59
Calibration
To maintain the performance of the timer/counter, we recom-
mend that you calibrate the timebase of your instrument every
year, or more often if you require greater timebase accuracy.
If your applications utilize the voltage measurement capabili-
ties of this counter series, you should also calibrate the voltage
ranges with a good calibrator.
Calibration should be performed with traceable references
and instruments at a certified calibration laboratory. Contact
your local service center for information on calibration facili-
ties in your neighborhood.
As both timebase and voltage calibration are closed-case
menu-controlled procedures that require no manual adjust-
ments on the DUT, you can perform the task on your own
without infringing the safety regulations, provided you pos-
sess the required skill and have access to the necessary cali-
bration equipment.
To know the present status of your instrument, test your coun-
ter from time to time. The test can be made according to the in-
formation in Chapter 2, “Performance Check.”
General Principles
The inherent meaning of calibration is to measure and record
the deviation of a parameter from a known reference. Data
from subsequent calibrations under similar ambient condi-
tions form the calibration history, from which you can draw
conclusions regarding aging characteristics.
Consequently calibration does not necessarily include the
next natural step in the procedure, i.e. adjustment in order to
make the instrument meet the original specifications.
The calibration procedure for these instruments also implies
automatic adjustment, so if you want a continuous history re-
cord, you should follow the simple rules of thumb below that
summarize the basics of all calibration, frequency as well as
voltage.
• Place the instrument in its calibration environment,preferably at an ambient temperature of +23 ± 2 °Cand power it up.
• Let the instrument assume its final internal operatingtemperature. Allow at least a warm-up period of twohours before proceeding.
• Measure the deviation and record the value. Use a ref-erence source whose uncertainty is at least an orderof magnitude less than that of the DUT.

tion.
• Start the calibration & adjustment procedure and fol-low the instructions.
• Measure the deviation and record the value.
• Check that the parameter meets its specification.
The Calibration Submenu
When used for the first time, this submenu can be activated
from the USER OPT menu after first entering the fixed pass-
word 62951413. All calibrations that can be performed manu-
ally are controlled from here. Internal delays can be compen-
sated for as well as aging of the timebase and voltage refer-
ences. All calibration procedures are performed without hav-
ing to remove the instrument cover. In this way it is easier to
keep the calibration environment as close to the operating en-
vironment as possible. No special tools are necessary, and live
parts are not exposed to the operator, who is guided through
the procedures by instructions on the instrument display. The
whole concept is known as Closed-Case Calibration.
NOTE: The timer/counter must have been switched on for at
least one hour before you start any calibration.
When the instrument leaves the factory, the calibration data is
stored as factory calibration that cannot be changed by the
user.
There is one active set of calibration data. It can be a user set
or the factory set. If a user set is active and a new user calibra-
tion procedure is initiated, then the older set of data is stored to
make it possible to return to the earlier calibration status.
Password Protection ON/OFF
The default setting on delivery for the password protection is
ON but can be changed to OFF after the first-time use if so de-
sired. Activate or deactivate the password with this key.
Internals
Certain internal delays are measured in order to correct the re-
sults of real measurements. This is done without applying ex-
ternal signals. This procedure needs only be run after firm-
ware upgrading, or if repair work has been done on the mea-
suring logic or the analog interpolators.
Press Start Calib to run the procedure. The new calibration
will be the active calibration.
� Calibration via the GPIB or the USB
The calibration can also be performed by sending commands
over one of the interface buses.
Always end the commands with the Operation Complete
Query *OPC?
Use the following command sequence:
:CAL:DEL:INIT;*OPC?
:CAL:DEL:START;*OPC?
:SYST:ERR? -- check for errors --
:CAL:DEL:STOR
Timebase
A reference frequency with adequate accuracy must be con-
nected to Channel A. Timebase calibration should be per-
formed regularly at intervals that depend on the timebase it-
self and the user application. Read more about the procedure
under Frequency Reference below.
Voltage
A sequence of voltage levels from a dedicated calibrator must
be applied to Channel A and Channel B. Voltage calibration
should be performed regularly if the user application calls for
traceable voltage measurements. Read more about the proce-
dure under Voltage Reference below.
Restore
You can make a stored set of calibration data, either a user set
or the factory set, the active calibration. If the previous active
calibration was a new user calibration, then it will be lost.
Frequency Reference
The frequency of the reference crystal oscillator is the main
parameter that influences the accuracy of a counter. External
conditions, such as ambient temperature and supply voltage,
affect the frequency, but aging is also an important factor.
Note that frequency adjustment only compensates for devia-
tion due to aging.
Some important points
The two optional high-stability oscillators, type OCXO, have
been built into an oven to keep the oscillator temperature as
stable as possible. Continuous operation is also important for
optimum stability. Option PM6690/_6_, for example, has an
aging/24h that is 1x10-10 when operating continuously. After a
power interruption, the oscillator drift is higher and the speci-
The Calibration Submenu 7-3
fication of 1x10-10 per 24h is reached only after 48h of contin-
uous operation.
– The frequency uncertainty for standard oscillators is
mainly dependent on the ambient temperature. Variations
in ambient temperature between 0 �C and +50 �C may
cause a frequency change of up to 100 Hz, whereas the
aging per month is only 5 Hz. During warm-up the tem-
perature increase inside the counter will affect the oscil-
lator for about two hours.
� How often should you calibrate?
In the table on the preceding page you can see the uncertainty
of your time base oscillator for various MTBRC (Mean Time
Between Recalibration) intervals.
Compare the requirements of your application with the values
in the table, and select the proper MTBRC accordingly.
Please note that the frequency uncertainty when operating in a
temperature controlled environment is different from field
use. See the two sections in the table.
�When adjusted, keep in mind that the referencecrystal oscillator will be compensated only for fre-quency deviation caused by aging.
Timebase Calibration Procedure
� Test Equipment
The instrumentation outlined here is an example of equipment
meeting the minimum requirements for calibrating the differ-
ent timebase options. You are free to choose other equipment
as long as its performance is adequate for the purpose.
A suitable reference oscillator can be derived from a number
of sources, the specifications of which determine the type of
DUT timebase option that can be calibrated.
The table suggests a number of possible combinations. Re-
member this rule of thumb: the reference should be at least
five times better than the DUT for a reliable calibration result.
� Work Instructions
– Determine the minimum requirements of the reference
oscillator and make a signal meeting these requirements
available at your test site.
NOTE: You can use a number of different calibration fre-
quencies for the DUT: 1 MHz, 1.544 MHz, 2.048 MHz,
5 MHz and 10 MHz.
– Place the DUT in its calibration environment, preferably
at an ambient temperature of +23 ± 2 °C and power it
up.
– Recall the default settings by keying in the following se-
quence:
USER OPT� Save/Recall �
Recall Setup � Default
– Let the DUT assume its final internal operating tempera-
ture. Allow at least a warm-up period of two hours be-
fore proceeding.
– Connect the reference oscillator signal to Input A on the
DUT.
– Select 10 s measuring time (under SETTINGS) and mea-
sure the frequency.
NOTE: Use a measuring time that is long enough to meet the
required resolution (see Table 7-1) or use statistics to
find the mean value of multiple measurements.
– Calculate the relative deviation of the internal timebase
as �rel = -(fmeas- fref)/fref.
– Translate this value to an absolute deviation �abs of the
internal 10 MHz timebase by using the expression:
�abs = �rel � 107 (Hz)
– Note this value as the calibration state before adjust-
ment, and decide if an adjustment is necessary according
to the applicable criteria.
– Stop here if an adjustment is not necessary. Otherwise
go on.
– Go to the Calibration Submenu and select Timebase.
– Press Calib Freq and select one of the possible frequen-
cies, or let the counter decide on its own by accepting
the preselected Auto setting.
– Start the calibration procedure by pressing Start Calib
and follow the instructions on the display.
– You must enter a date at the end of the procedure in or-
der to make the result the active user calibration.
– Measure the external reference frequency once more,
and calculate the deviation of the internal timebase in
the same way as before the adjustment. Note this value
as the calibration state after adjustment.
– Compare the two deviation values, and check that the
calibration procedure has been successful.
– Fill out the calibration protocol if required.

Voltage Reference
Although a counter/timer is chiefly an instrument for measur-
ing time and frequency related parameters, this instrument
also has voltage measurement capabilities that you can benefit
from. Under certain circumstances you can do without a
DVM in a test system, but then you have to calibrate and ad-
just the built-in voltage reference regularly to ensure the spec-
ified uncertainty.
Voltage Calibration Procedure
� Test Equipment
You should preferably use a dedicated DC voltage calibrator
with an uncertainty at least a magnitude less than the measure-
ment specification (see Chapter 8 of the Operators Manual).
Alternatively you can use a stable laboratory power supply
with an external precision voltage divider, for instance a
ten-turn potentiometer, in combination with an adequately ac-
curate DVM for verification.
Note: In contrast to a DVM the counter/timer has a wide-
bandwidth input, and the voltage calculation principle
is based on peak-to-peak measurements rather than
mean value or RMS measurements. This means that
HF noise that is often present at the output of standard
calibrators and power supplies must be filtered out
when the test voltages are applied to the counter in-
put. Always use shielded test leads that are as short
as possible.
� Work Instructions
– Arrange your test setup according to the outline given
above.
Note: Both Input A and Input B should be calibrated. If
you want a traceability record you should apply a num-
ber of positive and negative DC voltages covering the
dynamic range and write down the deviations. Use the
following list:
+50 V, +20 V, +5 V, +2 V, +0.5 V, 0 V, -0.5 V, -2 V, -5
V, -20 V, -50 V
– Key in the following sequence on the DUT.
USER OPT � Calibrate � (Enter Password if enabled)
� Voltage � Start Calib
– Follow the step-by-step instructions on the display.
– You must enter a date at the end of the procedure in or-
der to make the result the active user calibration.
– If you want a traceability record, verify the calibra-
tion/adjustment procedure by applying the same list of
voltages as above and write down the deviations.
– Fill out the calibration protocol if required.
� Voltage Calibration via the GPIB or the USB
The following DC voltages should be applied to the
timer/counter in this order: +50, +20, +5, +2, +0.5, 0, -0.5, -2,
-5, -20, -50 V, first to Input A(1) and then to Input B(2).
If you cannot generate the exact voltage, a voltage in the vi-
cinity of the required voltage can be used, but the value must
be sent in the bus command; two values between +50 and
+5 V, seven values between +5 V and -5 V, and two values be-
tween -5 V and -50 V. One value should be near zero.
Always end the commands with the Operation Complete

Adjustments
Preparations
Before beginning the adjustments, power up the instrument
after removing the cover (see Chapter 3) and leave it on for at
least 60 minutes to let it reach normal operating temperature.
WARNING: Live parts and accessible termi-
nals which can be dangerous to life are
always exposed inside the unit when it is
connected to the line power. Use extreme
caution when handling, testing or adjust-
ing the timer/counter.

Input Amplifiers
Check the power supply voltages according to the instructions
on page 7-13 before proceeding to the next step.
All adjustments on the input amplifiers must be made in the
specified order.
The input amplifiers are enclosed in an RF shield consisting
of a metal lid that is soldered to two of the shield clips on the
main circuit board. Without these solder joints there is a risk
of the lid coming off, should the instrument be subjected to
heavy bumps.
There are two alternative ways to adjust the input amplifiers.
One is to remove the shield to gain access to all trimmers and
test points on the top side of the main circuit board. Don't for-
get to put the shield back and restore the solder joints. The
other way is to access the trimmers via the holes in the shield
lid and to use the test points on the bottom side of the main cir-
cuit board. Place the instrument on end to get access to both
sides of the main circuit board.

8-2 Replacement Parts, Introduction
Note: There are two variants of the main PCB, Version A and
Version B. Refer to page III for closer information.
Standard Parts
Electrical and mechanical replacement parts can be obtained
through your local service organization or representative. How-
ever, many of the standard components can be obtained from
other local suppliers. Before purchasing or ordering replace-
ments parts, check the parts list for value, tolerance, rating, and
description.
If the value of the physical component differs from what is de-
scribed in the parts list, you should always replace the part with
the same value as originally mounted.
NOTE: Physical size and shape of a compo-
nent may affect the performance of the
instrument, particularly at high frequencies.
Always use direct replacements unless it is
known that a substitute will not degrade the
performance of the instrument.
Special Parts
In addition to standard electronic components, the following
special components are used:
– Components that are manufactured or selected by Fluke to
meet specific performance requirements.
– Components that are important for the safety of the instru-
ment.
Both types of components may be replaced only by components
obtained through your local service organization.
Timebase reference oscillators, except those based on standard
crystals, cannot be repaired in the field but are replaced by
means of a factory exchange procedure. The same repair method
applies to the prescaler options.

How to Read the Diagrams
This chapter contains circuit diagrams and component layout
information.
Signals
The signal designations reflect the functions. ADCDATA0,
for instance, means DATA BIT 0 from the ADC (Analog/Dig-
ital Converter).
Three different types of graphic symbols are used to mark ref-
erences for continued connection somewhere else in the dia-
gram.
This arrow is used if the reference to a supply
voltage is directed to a point located on the same
sheet. The example means that the supply voltage
-2.1V can also be found elsewhere on the same sheet.
This arrow is used if the reference to a supply
voltage or a signal is directed to a point located
on another sheet. The example means that the
supply voltage +3.3VD goes to sheet 1, 2, 5, 7 and 8.
A broken line with a signal designation label
means that this particular signal can also be
found elsewhere on the same sheet.
Circuit Symbols
The diagrams are computer-drawn. The symbols conform to
IEC standards. These symbols are designed to be logical and
easy to read.
The component number is written above the symbol. The type
number is written below the symbol
Inside the symbol there is sometimes an abbreviated descrip-
tion of the circuit’s function.
Pin numbers are written outside the symbol and, if the circuit
is complex, the pin functions are written inside.
A small circle on a pin indicates that the input/output inverts
the signal.
The signal flow through the circuit is normally from left to
right.
Resistors, Capacitors, Diodes,Transistors and Other Components.
These components are similar to the old-fashioned,
hand-drawn symbols. They have their component numbers
above or beside the symbol and their value or type number be-
low the component number.

How to Replace SurfaceMounted Devices
Most of the components in this instrument are mounted on the
surface of the board instead of through holes in the board.
These components are not hard to replace but they require an-
other technique. If you do not have special SMD desoldering
equipment, follow the instructions below:
10-2 How to Replace Surface Mounted Devices
Figure 10-1 Heat the leads and push a thin aluminum
sheet between the leads and the pca.
Figure 10-2 When removed, clean the pads with
desoldering braid.
Figure 10-3 Place solder on the pad.
Figure 10-4 Solder all leads with plenty of solder, don’t
worry about short-circuits at this stage.
Figure 10-5 Remove excessive solder with desoldering
braid..
Figure 10-6 Use a strong magnifying glas to make sure
there are no short/circuits or unsoldered
leads.
Figure 10-7 Attach the IC to the pad with solder.
Electrostatic Discharge
Almost all modern components have extremely thin conduc-
tors and metal oxide layers. If these layers are exposed to elec-
trostatic discharge they will break down or perhaps even
worse, be damaged in a way that inevitably will cause a break-
down later on. The Electro-Static Discharge sensitivity of
MOS and CMOS semiconductors have been known quite a
while, but nowadays bipolar semiconductors and even preci-
sion resistors are ESD sensitive. Consider therefore all com-
ponents, pc-boards and sub-assemblies as sensitive to electro-
static discharge. The text below explains how you can mini-
mize the risk of damage or destroying these devices by being
aware of the problems, and learning how to handle these com-
ponents.
ESD sensitive options are packed in conductive containers
marked with this symbol.
• Never open the container unless you are at an ESD pro-
tected work station.
• Use a wrist strap grounded via a high resistance.
• Use a grounded work mat on your workbench.
• Never let your clothes come in contact with ESD sensitive
equipment even when you are wearing a grounded wrist
strap.
• Never touch the component leads.
• Never touch open connectors.
• Use ESD-safe packing materials.
• Use the packing material only once.
• Keep paper and nonconductive plastics etc. away from your
workbench. These may block the discharge path to ground.
