Measuring Parameters with Cable
This section introduces an example of how to detect the location of a mismatch that occurs
in a cable by using the time domain function.

Overview of evaluation procedure

In this example, a DUT is evaluated according to the steps shown in Table 15-8.
Table 15-8 Evaluation Procedure for Deviation from Linear Phase
