After calibrating Test Set ports, use a quality load and short to verify the
calibration on each port or end of the test cable. Measure reflection and confirm
the return loss is as expected. If the result is not as expected, repeat the
calibration without the Test Set and ensure that the network analyzer is in
standard (non-multiport) mode.
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.
