MODEL 9354-1 UNIVERSAL TRANSIENT GENERATOR
for susceptibility tests MIL-STD461C/D/E, DO-160C/D and other specifications
APPLICATION
The Model 9354-1 Universal Transient
Generator was especially designed for the
performance of a variety of pulse susceptibility
tests on subsystems and/or equipment, in
accordance with MIL-STD-461D and E, method
CS116; RTCA DO160D, section 22; MIL-STD-461C,
methods CS10 and CS11.
Through the use of many Solar accessories,
including various reactive networks and coupling
devices, as well as other commercially available
items such as loop antennas, parallel plates,
and TEM cells, the generated output may be
modified and applied to other specifications.

DESCRIPTION
Model 9354-1 Universal Transient Generator
provides nine selectable waveforms, including
six damped sinusoidal pulses (10 KHz, 100 KHz,
1 MHz, 10 MHz, 30 MHz, and 100 MHz) and
three double exponential pulses (6.4 S, 70 S
and 500 S).
Auto pulsing of the sinusoidal repetition rate
is internally adjusted from 0.5 to 1.0 pulse per
second. A front panel-mounted push button can
be used to manually trigger single pulses. The
peak amplitude of the selected output pulse is
adjustable as a percentage of the charge voltage.
The six damped sinusoidal waveforms were
designed to meet the requirements of
MIL-STD-461D and E, method CS116, when
applied in accordance with the test method of
MIL-STD-462D. Continuous tunable frequencies
can be obtained by the use of the optional
variable frequency modules.
These same waveforms are applicable to the
requirements of MIL-STD-461C, methods CS10
and CS11, when applied in accordance with the
test method of MIL-STD-462, Notice 5.
The 1MHz and 10 MHz damped sinusoidal
waveforms have been extended to a peak open
circuit voltage of 3200 volts and a calculated
short circuit current of 128 amperes to meet
the requirements of RTCA DO-160D, Section 22,
Table 22-2,waveform 3.
The three double exponential pulses were
designed to meet the requirements of RTCA
DO-160D, Section 22, Tables 22-2 and 22-3.
Table 1 lists the test level that can be achieved
from the Model 9354-1.
FEATURES
Panel-mounted digital voltmeter. Monitors the
adjusted open circuit discharge voltage.
Pulse rates up to two pulses per second
maximum (factory adjusted).
Single pulse feature enables controlled
isolation of transient effects.
Output voltage adjustable from 0.1% to 100%
of selected discharge voltage.

AVAILABLE ACCESSORIES
Variable and Step Frequency Modules. Provides
tunable frequencies for injection of damped
sinusoidal wave forms from 10 KHz to 100 MHz
when used with Model 9354-1. Five individual
modules waveforms cover the entire frequency
range required by MIL-STD-461D. Detailed
information provided on separate data sheet.
Type 9335-2 Universal Coupling Device. An
inductive injection device that provides voltage
and current transfer of 1:1, 1:1.5 and 3:1 voltage
step-up (current step-down) as well as 2:1 voltage
step-down (current step-up).For maximum power
transfer, these ratios are selected by connecting
to one of the four BNC connectors. This device,
