
Each connector or jumper will show up as a spike. If it is larger than the
typical value, check the connector for damage.

Spikes where there are no components represent faults. Note the dis-
tance and check the line at that point for damage.

The largest spike is usually due to the antenna. Typically the trace after
the antenna can be ignored.

If a selected 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 chosen. Such a spike is known as an alias.
Note: To avoid aliasing, always set the measurement distance to a
value that is a few feet or meters greater than the entire length of the
cable system.

A large spike (fault) near the Site Analyzer will mask other faults farther
away. When a large spike near the Site Analyzer is found, fix it and then
repeat the Fault Location measurement.
