1IntroducingtheHP 80000

The HP 80000 system consists of 2 part.s:

1. HP IC29OOA Mainframe.

2. II I’ EZ90 1 A Expansion Framcl.

The HP 80000 is of modular st.ruc*t ure using plug-incards with a wide range of data gent~ration and st,imuluscharact erist ic*s. This allows t hc user to c*onfiguro t h(tsyst orn with only t hosct modules nccldcd for a partic*ularapplic*at ion.

The 1IP 80000 Dal a Generat,or System provides a modularplatform for performanc~r data and clock gc’nerat orsthat oflcr prtlctiscl t,est pat,t ems t.o charact.crizcl highperformance devices. These devices may b? fast DACSfor image presentation, multi-channel receivers, parallelt,o serial ccmverters, custom IS1 ICs etc . . .

The basic syst cm is a Mainframe withboot.up/confiKuration software, a Microprocessor Boardand an internal Clock Board fit.tcd, to enable it to bc usedas an E29OOA Data Generator. 1Jp to three HP E29OlAExpansion Frames can be connect.ed to the Mainframe.

The Mainframe and Expansion Frames each providrl fiveslot cardcagcs in which any mix of the following modulescan bc fit t (ld:

IStarting the System

1. Make sure t.hat the Lint switch al the rear of theMainframe is swit(>hed off, and the Stand-by switch at.the front. is switched to Stand-by.

Make sure t,hat the correct Line voltage setting is selectedand that the correct. line fuse is installed. See theInst,allat.ion Guide.

2. Connect the EBROOA Mainframe t.o the power supplyand swit,ch on the Line switch at the rear.

3. Insert an HP 80000 system-disk into one of the diskdrives.

4. If you have a mouse and/or keyboard, you can plugthem into the HP-I-III, socket on t,hc front of t.hcMainframe.

5. Swit.ch thcl Stand-by swit.ch at the front of theMainframe to On.

The Mainframe performs a s?lf-t,est., searches fora syst.em-disk and loads its operating-syst.em anduser-interface from the system-disk. This may take up toone minute.

41GHz Data Generator Random Data Concepts

Introduction You can use the HP 80000 to generate various types ofrandom data in different ways. To summarize:

Hardware Generated PRWS 23You can configure E2903A Data modules to produceHardware generated Pselldo-Kandom-Word-S(~q~len(~~~sbased on PROS ‘,?‘“-I. The data is out put during t.hcPHWS23 part of lhc data sequence and does not use updat.a memory in the modules and cannot bc edited. PRWSdata can be generated by groups of 2, 4, 8 or 16 channels.

Fixed-length Memory-based PRWSYou can put fixed-length PRWS dat.a int,o the Preamble orCycle part. of the sequence using the [PRWS) Pattern onthe m menu on the Data Listing page. The length ofthe data depends on the PRBS polynomial chosen, as thecomplete sequence is writt,en int.o memory. The PRWSdata can be put. into Groups of 2, 4, 8 or 16 channels.

Fixed-length Memory-based PRBS with Zero Substition or FixedMark Density

You can put fixed-length PRBS data with either ZeroSubst,it,ution or fixed Mark density, into the Preamble orCycle part of the sequence. Select (PRWS) on t,hc mmenu on the Data Listing page, and then change thePattern to CZeroSub_) or [MarkRatio_). The length of the datadepends on t.he PRBS polynomial chosen, as the completesequence is written into memory. The data is written intoa single channel within a Group,

1 GHz Data Generator Random Data Concepts 4-l

Variable-length Random DataYou can put, PRBS-based random data into any 1engt.h ofcontiguous vectors in the Preamble or Cycle part of t,hcsequence. Use tf?andom Pattern) on the @ menu on theDat,a Listing page.The PRBY polynomial is automaticallychosen t.o be the shortjest sequence that will fill thevector range chosen. You can choose the number ofchannels into which the data is written.

Hardware Generated PRWS 23n Each channel on an E2903A Data Module can output

a hardware-generated Pseudo-Random-Bit -Sequenc,ebased on t.hc polynomial 2’“-1.

n The hardware-generated data is generat cd cont.inuouslybut is output only during the PRWS23 part. of the datasequence. It cannot be edited, but does not occupy an)data memory.

n The PRWS23 segment of t,he dat,a sequence can beany length from 0 to 131072 in multiples of 8. Notethat t,his is insufficient. to generate the complet,e 2”“-1sequence, but see “Generating a Comp1et.e 2”3-lPRWS”.

n For Groups of 2, 4, 8 or 16 channels, the PRBSof each channel is “phase-shifted” so that a truePseudo-Random-Word-Sequence is generated whichrecreat,es the original PRBS if correct.ly multiplexed.

PRWS23 Channel Grouping RulesYou can generate PRWSs with 2, 4, 8 or 16 bits perword. IJse the @hamel Config) page to configure groupsof channels. However, you must follow some rules onGrouping the channels to achieve true PRWS:

4-2 1GHz Data Generator Random Data Concepts

2 Bit Word Groupn Bot,h channels must be from the same E2903A module.n You can Group either Channels 0 and 1, or 2 and 3.

4 Bit Word Groupn All 4 channels must be from the same E2903A module.

8 Bit Word Groupn All 4 channels from two E2903A modules must be

grouped together.

16 Bit Word Groupn All 4 channels from four E2903A modules must be

grouped togel her.

Note If the c*hannels of several modules are grouped togct her,without meeting t.he above Grouping rules, each moduleis treated as an independent 4 Bit Word Group.

PRBS Phase Shifting In order to generate a true PRWS which can bemultiplexed to recreate the original PRBS, the PRBS oneach channel within the word is “phase-shifted” relativeto the original PRBS sequence. ‘Ruble 4-l lists the channelphase-shifts implement,ed in the HP 80000 depending onthe Channel Grouping used, and gives the equivalent,start-bit number for a 2”3-1 PRBS.

Figure 4-l shows an example of a 2 Bit PRWS generatedon Channels 0 and 1 of a module. Each PRWSsegment is a window int,o the continuously runninghardware-generated PRBS. Not,e the “Phase-shift” of thePRBS on channel 1.

Generating a Complete 223-1 PRWSThe maximum PRWS segment-length of 131,072 bitsis insufficient. t.o generat.e the comp1et.e 2”3-1 PRBSs(8,388,607 bits). Therefore, to generat.e the completesequence repeatedly, without, interruption by cycle-data:

n Set the Cycle length to 0 (zero).

n Set the PRWS23 length to, for example, 8.

n Set the Repeat count. to infinite.

1GHz Data Generator Random Data Concepts 4-5

I4

Fixed-length Memory-based PRWSYou can put a PRWS into the Preamble or Cycle part,of the data sequence. The data can then be edit.ed ormanipulated like any other vect,or data.

You can choose the PRBS polynomial used as a basis forthe PRWS:

The length of i.hc PRWS data is determined by thePRIH used.

For Groups of 2, 4, 8 or 16 channels, l.hc PRHSof each channel is “phase-shifted” so that a truePseudo-Random-Word-Sequence is generat cd whichrecreates the original PRBS if correct.ly multiplexed.

Memory-based PRWS Channel Grouping RulesThe same Channel Grouping rules apply for amemory-based PRWS as for t,he hardware-generatedPRWS23. Set “PRWS23 Channel Grouping Rules”.

PRBS Phase Shifting The same channel “phase-shifts” are used as for ahardware-generated PRWS23. Refer to lablc 4-1, butnote that. t.hc Start-bit numbers do not apply, as the PRBSlength is not 2”3-1 but depends on the PRBS chosen.

Variable-length Random Datan You can put. random PRBS data of any length into the

Preamble or Cycle part. of the dat.a sequence. Use(Random Pattern) from the (Edit) menu on the Data Listingpage.

n The PRBS polynomial is chosen automatically,depending on the length of dat~a (vect.or range) to befilled.

w The PRBS data is “phase-shifted” bet.weenneighbouring channels.

PRBS Polynomial and Data LengthYou define the data length (vector range) on the(Random Pattern] window from t,hc IEdit) menu on theData Listing page by entering the start and end vect,ornumbers. The data length determines the polynomialused to generate the data:

PRBS Phase Shift

H 2(“-l)-l < Length < 2”-1, Polynomial 2”-1(n= $4, 5.. . . .14)

n Length < 8, Polynomial 23-1

n Length > 2l”-1, Polynomial 214-1

The PRBS phase shift between channels depends on thenumber of channels you are writing to:

n Phase Shift = l/p wit,h p = 1,2,4,8,16,32and p > number of channels

w If number of channels > 32, Phase Shift = l/32n If polynomial = 2”-1 and number of channels > 8,

Phase Shift = l/8

H If polynomial = 2”-1 and number of channels > 16,Phase Shift = l/16

The HP 80000 supports multiple logical instruments.Each logical inst,rument has its own command andparameter set. In order to access the commands of aparticular logical inst.rument, you have to select it. usingthe :INSTrument:SELector :INSTrumen:NSELectcommands. The following logical inst.ruments arecurrently supported:

n SYSTEM

n SYSTEMCLOCK

n DATAGEN 1 C;fl%

n DGlGIIZ128K

This ins1 rument select,ion process corresponds toinst rumcnt -menu sektion when using t.he IJscr Interface.The logicral inst.rumcnt names corresnond to t,hc_,instrument-menus c-1, L-Clock), Data Gen 1GHz

and (Data Gen 1 GHz/l28kBit], which are available on theTop Level menu (See “Top Level page” in Chapter 2).Selecting one of t.hme m&us fro& ihe Top L&e1 menuallows you to use the User Interface pages for thatinstrument.. In the same way, selecting an instrumentvia HP-IH allows you to use the command-set for thatinstrument,.

The Command Hcferences for t,he instruments areseparated into the following chapt.ers:

SYSTEMCLiCK

D A T A G E N 1GHz

In addition there are some commands which areindependent of the logical instrument that you are using.These are listed in Chapt,er 6.

5-2 Introduction to Programming the HP 80000

Groups

Groups The DATAGEN I GHZIDG 1 GHZl28K logical instrumentsupports Channel Groups. A Channel Group is definedas a list of up to 32 channels bound togct,her under auser-defined name. You can think of a Channel Groupas sub-instrument within t,he Logical Instrument. Manyof the commands are Group-orient.ed and operateonly on the currently selected Channel Group (See“[:DIGital]:GROup[:SELect]” in Chapter 9).

Note that there are two predefined Channel Groups:

ALL All defined Channel Groups. If you selectALL then the subsequent Group-oriemedcommands apply to all defined ChannelGroups.

NONE No Group. If you selwt NONE thenyou effectively disable subscqucntGroup-oriented commands since they will 5have no effect.

You can use some of the Group-oriented commands t.oaddress a specific channel within the selected Group byusing a Channel Number suffix in the command. Thiscapability is documented in the Reference section of theindividual commands.

The HI’ 80000 has a st.atus reporting syst.em conformingt,o IEEE 488.2 and SCPl, as shown in Figure 5-l. Eachstat.us group is made up of component. registers, as shownin Figure 5-2.

5-4 Introduction to Programming the HP 80000

Status Groups

Condition Register A condition regist,er contains the current stat.us of thehardware and firmware. It is continuously updat,ed andis not latched or buffered. You can only read conditionregisters. If there is no command to read the conditionregister of a particular status group, then it is simplyinvisible to you.

Transition Filters Transition filt,ers are used to det.ect changes of state inthe condition register and set. the corresponding bit in theevent. regist.er. You can set, transition filter bits to detect.positive transitions (PTR), negative transitions (NTR) orbot.h. Transition filt.ers are therefore read-write registers.They are unaffected by *CLS.

Event Register An event regist.er latches transition event.s from thecondition register as specified by the transition filters.Querying (reading) t,hc event rcgist cr clears it., as does the 5*CLS command. There is no buffering, so while a bit isset, subsequent transition events are not recorded. Event.registers are read-only.

Enable register The enable register defines which bits in an event registerare included in the logical OH into the summary bit. Theenable register is logically ANDed with the event registerand the resulting bit,s ORed into the summary bit.. Enableregisters are read-write, and are not, affect,ed by *CLS orquerying.
