A method and system for detecting intermodulation emissions, such as passive intermodulation emissions, is provided. The method comprises retrieving signal quality measurement (SQM) data, and determining whether there is an intermodulation hit in the SQM data. If there is no intermodulation hit, the SQM data is stored in a first data set; if there is an intermodulation hit, the SQM data is stored in a second data set. The method then determines whether there are one or more faults in the first data set. If there are, a confirmation count for an intermodulation failure is cleared, and the method starts again. If there are not one or more faults in the first data set, a determination is made whether there are one or more faults in the second data set. If not, the confirmation count is cleared, and the method starts again. An intermodulation failure can be confirmed if there are one or more faults in the second data set.
