7 Return Loss Measurement
How to Measure Return Loss
It is not necessary to make new calibration measurements for each DUT.
You can make the calibration measurements for your system, and then
measure the return loss of many devices.
The value shown in the result field for the Return Loss channel is the
measured return loss.
1 Attach the DUT to the measurement patchcord. In the example shown
in Figure 120 on page -198, the DUT is a connector pair.

Tip: Terminate your system close to the DUT to make sure that you are
only measuring reflections from the DUT.
