1. A computer-implemented method for detecting intermodulation emissions, the method comprising:

  • (a) retrieving signal quality measurement (SQM) data;

    (b) determining whether there is an intermodulation hit in the SQM data;

    (i) storing the SQM data in a first data set if there is no intermodulation hit;

    or(ii) storing the SQM data in a second data set if there is an intermodulation hit;

    (c) determining whether there are one or more faults in the first data set;

    (i) clearing a confirmation count for an intermodulation failure if there are one or more faults in the first data set; and

    (ii) returning to step (a) to restart the method;

    (d) determining whether there are one or more faults in the second data set if there are not one or more faults in the first data set; and

    (i) clearing the confirmation count if there are not one or more faults in the second data set; and

    (ii) returning to step (a) to restart the method.
