A splitter or directional coupler can be identified
although accurate measurements are difficult due
to multiple reflections. The 2nd cursor identifies the
splitter. The two reflections following are the ends of
each of the cable lengths.
A water-soaked cable will display a waveform with a
downward slope indicating the beginning of the water
and an upward rise at the end of the water. Generally,
the area between the two reflections will appear “
noisy.”
