Function
Sets PRF range. In EXT
DRIVE, it changes prf
oscillator to an aperiodic
1nput circuit.
Adjusts prf continuo u sly
between calibrated switch
positions. When set fully
clockwise, PRF switch is
calibrated. When PRF
switch is set to EXT DRIVE,
i',F control sets triggering
leve 1 of pulse generating
c1rcuits.
Sets pulse duration.
Sets pulse duration range
in decade steps.
Turns instrument on and off.
For negative main output
pulse.
For positive main output
pulse.
Adjusts amp litude
continuously between
switch positions.
Sets pulse amplitude
in ten steps from zero
to maximum.
For connection to an
external power supply
used to change de leve 1 of
of
output.
For delayed sync pulse.
Amount o(delay is
controlled by PULSE
DURATION controls.
For negative pre pulse.
For positive pre pulse.
For external drive signal.
For use with forthcoming
Type 1398-Pl DC Component
Control Unit.
