Spectrum Analysis of an antenna system can assist in locating the source of RF interference.  A Passive Intermodulation signal
can be traced to a specific frequency with the help of a Spectrum Analyzer and if the test operator is familiar with the possible
sources of interference signals the problem can be identified and possibly resolved.  In some cases the source of the problem is
an environmental interference or a signal from another broadcast carrier.  It may be that these problems can not be resolved, but
by identifying the source, the explanation of the issues can be included in the final report to the service provider.  This process
requires an experienced and professional test operator.  If these issues are not properly explained the crew performing the
installation may be held responsible for the unresolved problem.
The RF engineers that will review the final test results need to be confident in the work performed by the installation team and
the abilities of the test operator.  That can not happen without a full explanation of all negative findings that can not be
resolved.  It is not enough to simply conduct the test and record the results without an attempt to trace down the problem.
The Spectrum Analyzer will measure the noise level of an entire frequency spectrum and identify the specific frequency location
of any excessive interference or intermodulation signal and show it in a graphic display.  If the measurement is a match to the
PIM test result, this can prove the existence of an environmental source that can not be remedied.
Our testing services can be relied upon to uncover all of these issues and provide adequate explanation for the findings.
