Atec 9355-1 User Manual

MODEL 9355-1 PULSE GENERATOR

for MIL-STD461D/E CS115 susceptibility test

APPLICATION

Solar Model 9355-1 Pulse Generator is

designed to provide impulse excitation by
means of an injection probe placed around
interconnecting cables or power wires.The unit
uses a charged transmission line (50 ohms) to
generate a pulse with less than 2 nanoseconds
rise and fall time, and duration of approximately
30 nS, calibrated in a 50 ohm fixture to deliver up
to 5 amperes at a rate of 30 p.p.s. for one minute as
required by MIL-STD-461D/E,test method CS115.

DESCRIPTION

The charged line potential of the Model 9355-1
is adjustable from less than 2 volts to greater than
2000 volts. The repetition rate is variable from
less than 0.6 p.p.s. to greater than 150 p.p.s.,
or single pulses manually triggered by a panel
mounted push button. Digital displays monitor
the charging voltage and pulse repetition rate.

This unit can also be used as an impulse
calibrator to provide an adjustable spectral
output up to 150 dB V/MHz over the frequency
range of 1 KHz to 10 MHz constant within 1 dB.
