METHOD AND SYSTEM FOR DETECTION OF PASSIVE INTERMODULATION INTERFERENCE EMISSIONS
First Claim
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.

Abstract
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.

11. A system for detecting passive intermodulation emissions, the system comprising:
-
at least one data receiver that outputs signal quality measurement (SQM) data; at least one data storage device that saves the SQM data from the data receiver; at least one data processor operatively coupled to the data storage device; and a program module having instructions executable by the processor to; (a) retrieve the SQM data from the storage device; (b) determine whether there is a passive intermodulation hit in the SQM data; (i) store the SQM data in a first data set if there is no passive intermodulation hit;
or(ii) store the SQM data in a second data set if there is a passive intermodulation hit; (c) determine whether there are one or more faults in the first data set; (i) clear a confirmation count for a passive intermodulation failure if there are one or more faults in the first data set; and (ii) repeat instructions (a) to (c); (d) determine 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; (i) clear the confirmation count if there are not one or more faults in the second data set; and (ii) repeat instructions (a) to (d); (e) confirm a passive intermodulation failure if there are one or more faults in the second data set. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
