Patent ID: 8369812

Claim:
A method for detecting intermodulation emissions, the method comprising: (a) retrieving signal quality measurement (SQM) data generated by a receiver without any test signal transmissions; (b) determining whether there is an intermodulation hit in associated with the SQM data, the intermodulation hit defined as a condition that exists when one or more potential intermodulation product frequency or frequencies from a current set of normal operation transmit frequencies coincide with one or more monitored normal operation receive frequency or frequencies; (i) storing the SQM data in a first data set if there is no intermodulation hit; and (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.
