Bird Site Analyzer

76

Test for Fault Location

1. Connect the Site Analyzer to the cable being 

tested.

Note:

If you calibrated the Site Analyzer 

with a phase stable cable connected to its 
antenna port, do not remove the cable. Con-
nect it to the cable to be tested.

2. Wait at least 10 seconds for the sweep to update.
When you have a trace on the screen, you can do any of 
the following:

•

Hold the trace (refer to Measurement Hold, page 
78)

•

Add markers to the trace (refer to Markers, page 
79)

•

Save the trace (refer to Save Trace, page 92)

•

Print the trace (refer to Printing, page 89)
