Solar 8850-2 High Power Sweep Generator
Description
For Conducted Audio Frequency Susceptibility Testing.
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 level 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.
Features
- Manual or automatic frequency sweep from 20 Hz to 150 KHz
- Digital display of frequency and output voltage level or injected voltage level
- Remote sensing of voltage being injected into the Equipment Under Test
- Automatic leveling of output voltage as frequency is scanned or swept to 50 kHz
- Low output impedance for greater transfer of audio power
- Protective circuits prevent damage to output stage caused by power frequency feedback in typical a.c.
test setups - Up to 200 watts output into 2.0 ohm resistive load
Solar 8850-2 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 tests 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 enables the injection of sine wave audio voltages into active power lines supplying power to Equipment Under Test (EUT).
