13. Receiver Magnitude Compression

13. Receiver Magnitude Compression
Perform this test to verify the compression/expansion magnitude levels of the analyzer's
receiver samplers. Power sweeps from low to high power are made at designated CW
frequencies. A reference measurement is made while the signal to the receiver is
attenuated to avoid compression. The attenuation is removed and compression is observed
and measured.
Analyzer warmup time: 30 minutes
