connector
Adjusts rf output pulse from 0.2 to 2000 sec
PULSE WIDTH control and

X1-X10-X200-X1000 switch
0.2 to 2 sec
X1
X10
2.0 to 20 sec
40 to 400 sec
X200
X1000
200 to 2000 sec
Pulse width range overlap on the X10 and X200 multi-
plier positions provides pulse width from 20 sec to
40 sec
Adjusts delay between both rf output pulse and delayed
SYNC DELAY control and
16,17
sync output pulse from 0.3 to 2000 sec
LOW-X1-X10-X100 multiplier
Enables modulating output signals to be either internally
SELECTOR switch

or externally controlled. For external modulating signals,
the controls are set as follows:
a. Must be set to EXT(+) when a positive synchronizing
pulse or a positive modulating pulse is externally
applied.
b. Must be set to EXT(-) when a negative synchronizing
pulse or a negative modulating pulse is externally
applied.
C.
May be set to EXT(+) or EXT(-) when a sine wave
synchronizing signal is externally applied.
Adjust pulse repetition rate from 10 to 10,000 Hz

and RATE control
When FUNCTION switch is in the FM position, adjusts

the amplitude of the output sawtooth. (Adjusts devia-
tion of rf outputs when MODULATION SELECTOR
switch is set to EXT FM position.)
When FUNCTION switch is in FM position, couples
