Function
16
MODULATION Switch
Allows you to select any of six modes of operation of
RF OFF, CW, INTERNAL SQ WAVE; EXTERNAL
FM, PULSE, OR AM.
17
EXTERNAL PULSE Jack
Allows you to introduce an externally generated pulse
used to pulse modulate the RF output.
18
EXTERNAL AM Jack
Allows you to introduce an external sinusoidal signal
to AM modulate the RF output.
19
POWER Switch
When set in the upward position, it turns the signal
20
POWER INDICATOR
Lights green when the POWER switch is turned ON.
The following are located on the rear panel:
21
STABILIZER INPUT
Allows you to introduce a correction voltage to the
klystron repeller from an external phase lock
DANGER
STABILIZER INPUT is at 750 volts. Avoid bodily
contact. Always keep input covered when not in use.
22
RF MONITOR Jack
Allows the RF output from a fixed oscillator probe to
feed an external phase lock frequency stabilizer, or
for cases where synchronized dual RF output are
required.
23
AC INPUT Receptacle
Accepts power cord which connects line power to the
signal generator.
24
VOLTAGE RATING Switch
Allows instrument to adapt to two different line
voltages -115 VAC or 230 VAC.
25
FUSE Holder
Holds fuse of proper value to coordinate with
available line voltage:
1.5 amps for 115V or
0.75 amps for 230V.
26
GROUND Jack
A point at chassis ground potential for testing, or
auxiliary grounding of instrument.
