N-Port Calibration
It is recommended that you perform an ECal characterization to minimize the connections
required for multiple port calibration. The N4693AB Option M0F is recommended with cable
(85133F) if you are calibrating at the PNA-X and Test Set ports.
Characterize the ECal module with adapters that will not be used in the measurement of the
DUT. To characterize the ECal module select Response > Cal > More > ECal > Characterize ECal
Module.
Calibrate at the end of the test port RF cables and any adapters that are used to connect the
DUT. This removes the effect on the measurement of the DUT. Failure to do this will create ripple
and other measurement errors.
If measurement errors occur, ensure the newest version of firmware is
installed on the PNA-X. Measurement errors can be a result of firmware
algorithms. Consult with Keysight Service or firmware web page for the
latest PNA-X Option 551 firmware revisions and history
