4-6-2 SIGNAL GENERATOR OPERATION (SIMPLEX)
STEP PROCEDURE
------------------------------------------------------------------------
1.
Position front panel controls as indicated in Table 4-5.
FM/AM-1200S/A is now generating a carrier signal
at a frequency and output level of 150.2 MHz @
500 ].lV.
If a signal greater than 100 mW is applied to
the T/R Connector (11) while the FM/AM-1200S/A
is generating, the set will automatically switch
to the receive mode and only monitor the
signal(s) applied to this connector.
4-6-3 GENERATING AM OR FM MODULATED RF SIGNALS
STEP PROCEDURE
------------------------------------------------------------------------
1. Perform "STEPS IN SIGNAL GENERATOR OPERATION" (Ref. paragraph
4-6-2).
2. Apply FM modulation signal to carrier as follows:
4-36
05
a. Using Keyboard (18), depress "TONE'' Key and enter desired
modulation frequency and wave shape.
