13. Test Port Receiver Phase Compression
Perform this test to verify the phase compression/expansion of the analyzer’s test port
receivers. 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 warm-up time: 30 minutes
