Controlling the Test Set
N-Port Calibration
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 (85133F) if you are calibrating directly on 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 Module
-OR-
(Response > Cal > Cal Sets & Cal Kits > Characterize ECals...)
.
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 Option 551 firmware
revisions and history at
