Test for Fault Location
1. Connect the Site Analyzer to the cable being tested.
Note: If the Site Analyzer is calibrated with a phase stable cable con-
nected to its antenna port, do not remove the cable. Connect it to the
cable to be tested.
2. Wait at least 10 seconds for the sweep to update.
3. When a trace is on the screen, do any of the following:

Hold the trace. See “Measurement Hold” on page 51.

Add markers to the trace. See “Markers” on page 52.

Save the trace. See “Saving a Trace” on page 58.
