4. If you have selected a cable length that is less than
the total length of the cable system, the trace
might show a spike that is not really a fault, but
rather an echo from the remaining portion of the
cable that is beyond the length you chose. Such a
spike is known as an alias. To avoid aliasing, you
should always set the measurement distance to a
value that is a few feet or meters greater than the
entire length of your cable system.
5. A large spike (fault) near the Site Analyzer will
mask other faults farther away. When you find a
large spike near the Site Analyzer, fix it and then
repeat the Fault Location measurement.
Measurement Hold
Measurement Hold stops updating the display at the
end of the current sweep. Press the Hold key to toggle
the sweep hold off and on. A measurement is held
when there is a lock icon in the indicator ball. Mea-
surement hold is available in Measure Match mode
and Fault Location mode.
Follow the numbered steps in Figure 33, page 79 to
turn measurement hold on or off.
