1.1 1200 SUPER S OVERVIEW

GENERATE MODE

In Generate Mode, the 1200 SUPER S is anRF Signal Generator with the abil i ty to test a

Receiver using internal test ing abil i t ies such

as an Oscil loscope, Distort ion Meter, SINAD

M ete r and D V M . The 1200 SU PER S has

two internal modulation sources. There is a

1 kH z f ixed tone gene ra to r and a va r i ab le

t o n e g e n e r a t o r . A d d i t i o n a l l y , e x t e r n a l

modulation or a microphone can be used as a

modula t ion source . These modula t ions can

be used to modulate the RF Signal as FM or

AM modulation types.

Generate Mode test ing that can be performed

by the 1200 SUPER S includes:

Receiver Sensit ivi ty

Receiver Audio Distort ion

Receiver Audio Output Level

Receiver IF Bandwidth

DUPLEX MODE

In DUPLEX MODE, the 1200 SUPER S acts

as both Generator and Receiver to test both

sides of a Duplex System. The 1200 SUPER

1.2 TO INSTALL THE 1200 SUPER S

1 .2.1 AC POWER INSTALLATION

SETTING 120/240 VAC SWITCH

Prior to instal lat ion of ac power, the operator

must verify that the 120/240 VAC Switch isproperly set for the power source to be used.

Inspect and set the 120/240 VAC Switch as

follows:

1. R e mo v e a n y e x t e rn a l p ow e r s ou r c e s

from the unit .

2 . Loosen 4 capt ive screws and remove the

case from the unit.

3 . Remove 2 screws and Switch Cover to

expose AC Power Select Switch.

4 . Ver ify swi tch i s se t to proper se t t ing. I f

not , set switch. Current power set t ing is

visible on switch.

5 . Reins ta l l Swi tch Cover and Case .

INSTALLING AC POWER

Once 120/240 VAC Switch is properly set , acpower can be applied to the unit as follows:

1. C o n ne c t P ow e r C or d b et w e en p o w er

source and AC Power Input Connector.

2 . S e t PW R / S T AN D B Y/ B A T T S w i t c h t o

1 .2.2 DC POWER INSTALLATION

1. C o n ne c t P ow e r C or d b et w e en p o w er

source and DC Power Input Connector.

2 . S e t PW R / S T AN D B Y/ B A T T S w i t c h t o

PWR.

1 .2.3 BATTERY INSTALLATION

Once unit is activated on Battery Power, an

internal t imer is set that turns the unit off

a f t e r a p p r o x i m a t e l y 1 0 m i n u t e s o f u s e .

A d d i t i o n a l l y , t h e b a t t e r y v o l t a g e i s

monitored and if battery voltage fal ls below

a c e r t a i n l e v e l , t h e u n i t t u r n s o f f

automatically.

If the unit is not to be used for 30 days or

more, disconnect the battery. The battery is

charged whenever external ac or dc power is

appl ied , independent of the pos i t ion of the

POWER/STANDBY/BATT Switch.

Apply power as follows:

Set PWR/STANDBY/BATT Switch to BA TT.
