2-2 CONTROLS AND TERMINALS
PULSE OUT
This terminal is a Type N jack located at the lower right corner of the
front panel.
It is the output connection for the main pulse.
SYNC OUT
This terminal is a BNG terminal on the lower right side of the panel.
This terminal provides a voltage to synchronize an osciLloscope or
ather device for use with the Pulse Generator.
+r -
This toggle switch, on the panel above the SYNC OUT terminal, con-
trols the polarity of the synchronizing voltage fed to the SYNC OUT
terminal.
SYNC IN
The SYNC IN terminal is4a BNC connector on the lower left side of
the panel.
A voltage can be fed into this terminal to trigger the pulse
generating circuit.
SYNC SELECTOR
The SYNC SELECTOR knob selects two ranges of internally generated
pulse rates, and also selects necessary circuitry for external syn-
chronization from either positive or negative externally generated
sync pulses.
PULSE POSITION
The PULSE POSITION control adjusts the timing between the MAIN
PUlSE OUTPUT and the SYNC OUTPUT pulse.
Its main use is to
poaition the main pulse on an oscilloscope screen when the oscil-
loscope has been synchronized with the SYNC OUT pulse.
PULSE RATE
The PULSE RATE control, located on the upper left hand side of the
panel, adjusts the repetition rates of the pulse from 50 to 5000 cycles
per second in conjunction with the X1 and X10 position of the SYNC
SELECTOR switch.
