The Solar Electronics 7021-1 Phase Shift Network is used to phase out the primary power frequency without disrupting the injected frequency as seen on an oscilloscope during conducted audio susceptibility testing. The network prevents the power frequency from reaching the indicating device, but doesn't interfere with the normal power connection to the test sample.
Properly adjusted, the 7021-1 has no effect on the injected frequency, so the voltmeter or oscilloscope will indicate the injected level. It contains variable resistance and capacitance in a bridge-type circuit which is manually adjusted for null before the injected signal is applied.
The 7021-1 does a fine job on 50 Hz, 60 Hz, and 400 Hz power lines in either 115 V or 230 V single phase operation.
