Gating
Synchronous Gating:
Gating signal turns generator "on". First trigger output
pulse is coincident with leading edge of gate pulse. Last
output pulse is always generated with normal width even
if the gate pulse ends during the generation of the
output pulse.
Gate Input:
DC-coupled; voltage at open circuit gate connector
approximately +1.8V. Shorting current < 12mA. Input
impedance approximately 1600.
Gate Input Signal:
Voltage > +1.5V or resistor > 30012 from gate input to
ground enables the repetition rate generator.
Voltage < +0.8V or resistor < 1500 disables the
repetition rate generator.
Gate input is TTL compatible.
Maximum Input Signal:
<± 5V
External Width Input
External Width:
Output pulse width determined by the width of drive
input signal. Transition times and amplitude are selec¬
table. Repetition rate generator running provides trigger
output but these trigger pulses are not related to the
pulses at the output connector.
RZ Mode:
External input (switched to delay generator) determines
pulse
period.
Transition
times,
delay, width,
and
amplitude are selectable. Trigger output is not related to
RZ Mode output.
Input Signal:
Input Impedance 500; DC-coupled. Signal > +1V, at
least 7nS wide, provides output signal.
Maximum Input Signal:
<± 5V.
