keypad, enter the stop
distance for the part of
the cable that you wish
to zoom in on.
The greatest accuracy is obtained when you enter a
cable length slightly greater than the cable length
being tested. If you are not sure of the cable length,
enter a value 1.25 times the estimated length, and
enter a start distance value of 0 m (0 ft) as
described in Step 6. Depending on the return loss of
the antenna or device at the end of the cable, you
may see a high relative mismatch displayed at the
actual length of the cable
