N-Port Calibration with Analyzer

It is recommended that you perform an ECal characterization to minimize the connections required for
multiple port calibration. The N4691B Option M0F is recommended with cable (85131F) if you are
calibrating at the analyzer 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 Mod ule.
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
analyzer. Measurement errors can be a result of firmware algorithms. Consult with Keysight
Service or firmware web page for the latest firmware revisions and history at
http://na.support.keysight.com/pna/firmware/firmware.html.
1. To perform an ECal characterization select Response > Cal Wizard > Characterize ECal Mod ule and
follow the prompts.
2. Save the ECal characterization file. Refer to the Help menu for characterizing information.
