FUNCTION
MODULA nON switch
Three-position toggle
switch
3.
AM ~ Equipment generates or monitors amplitude
modulated signals.
4. SSB/DSBSC - Single Side Band/Double Side Band
Suppressed Carrier signal. The level of the generated
signal is not calibrated. Use it only for relative meas-
urements. Monitor SSB mode receives SSB signals
with the use
of the BFO.
5. SWP 1-10 MHz - Equipment generates a swept RF
signal having a sweep width of 1 to 10 MHz, con-
trolled by the Dispr /Sweep control. Monitor posi-
tion has no effect, equipment remains in generate
mode.
6. SWP 0.01-1 MHz - Equipment performs as in 5.
above except sweep width limits are 0.01 MHz to 1
MHz.
Controls the Code Synthesizer modulation source.
1. Cont - Continuous modulation signal output, gen-
erates repetitive cycles.
2. Off - No modulation generated. Terminates code
sequences.
3. Burst - Generates a single cycle, spring loaded,
returns to Off.
a. PL, Tone A, Tone B Output is present as long as
switch is held in Burst.
2-5
b. DPL, DPL Inv
c.
Tone Sequence
d. Tone Remote
DPL turn-off code as long
as switch is held down.
DPL code output when
switch is moved to Cont
position. Burst of DPL
turn-off code is output
when switch is moved from
Cont to Off.
Output is a single signaling
sequence.
Output is a tone remote ac-
cess sequence; leaves
Tone
A at a low level for trans-
mit-type commands until
the switch is returned to
Off.
