Receiver Compression Test

This test applies to the following models:

Port 1 is always tested. Port 2 is only tested if Option 211 is installed.

A source is used to provide a 10 dB power delta relative to 0 dBm at specific CW frequencies. This delta is measured by both the FieldFox receiver and a power meter. The difference between the two is considered to be the compression for the receiver at the given frequency.

This test requires the signal generator to have good repeatability. If repeatability is unacceptable, a warning message will be displayed.
