4.
Set the averaging factor to 512.
5.
At the adapter test port, perform a 2–port TRL calibration.
6.
Turn on the calibration.
7.
Connect the termination you wish to test to port 1.
8.
Measure the return loss (S
11
) of the load.
9.
After one complete measurement sweep, the displayed trace should look
similar to that shown in
10.
If necessary, update the trace.
11.
Use a marker to determine the maximum value on the trace. This marker
determines worst-case return loss.

Typical Termination Return Loss
In Case of Failure
If a termination fails this test, clean all flanges and carefully reconnect the
devices. Repeat the test. If the termination fails again, replace it. Refer to
