Limited by compression level and system noise floor. Noise floor is measured with full two-port error correction, 1024
averages.

This maximum power measurement assumes that the Agilent 85110A test set has its internal step attenuators set to 0
dB. The test can handle up to 20 W (+43 dBm) or power if the step attenuators are activated and an isolator is installed
(in the port 2 real panel link).
