Atec Solar-8850-2 - Manual

SOLAR MODEL 8850-2
200 Watt
HIGH POWER SWEEP
GENERATOR
for
conducted audio frequency
susceptibility testing
APPLICATION
The Model 8850-2 200 watt High Power Sweep Generator
was specifically designed for use with the Solar Audio
Isolation Transformers in making audio frequency
susceptibility test as required by Mil-Std-461E/F CS101. This
high power unit is especially suited for rapidly making tests in
the shielded room.
When used with the Type 6220-1A or 6220-2 Audio Isolation
Transformer, the combination enable the injection of sinewave
audio voltages into active power lines supplying power to
Equipment Under Test (EUT)
.
DESCRIPTION
The Model 8850-2 Power Sweep Generator provides audio
power in a manually tuned or sweeping mode for four
frequency bands covering 30 Hz to 150 KHz. The sweep rate
is compliant with the requirements of Mil-Std-461F for an
analog scan, approximately 0.0333 x frequency of oscillation
per second.
The frequency in kHz and output lever in volts r.m.s are
continuously displayed on two digital front panel meters.
When used in conjunction with the Type 7021-1 Phase Shift
Network and the Type 6220-1A Audio Isolation Transformer,
provision is made for sensing the audio voltage being injected
into the EUT and displaying it on the digital panel meter. In
this arrangement, the unit maintains a constant injection level
(up to a maximum of 7.5 volts r.m.s ) as the frequency is
scanned to 50 kHz.
