5.2.19 Gain Compression
This test measures the analyzer’s gain compression using two signals that are 1 MHz apart. First the test
places a -30 dBm signal at the input of the R3132 series (the R3132 series reference level is also set to -30
dBm).
Then the specified signal level is input to the R3132 series, overdriving its input. The decrease in the first
signal’s amplitude (gain compression) caused by the second signal is the measured gain compression.
