Patent ID: 6979992

Claim:
A method of analyzing electromagnetic interference in a building, comprising the steps of: defining a plurality of configurations, each configuration corresponding to a plurality of frequencies in a frequency range, the plurality of configurations including at least a first configuration corresponding to a plurality of frequencies in a first frequency range and a second configuration corresponding to a plurality of frequencies in a second frequency range, the first and second frequency ranges being discontinuous from each other; stationing a spectrum analyzer in a location in the building; instructing the spectrum analyzer to scan the frequencies in each configuration; leaving the spectrum analyzer unattended while it scans the frequencies in each configuration, wherein for each configuration, the spectrum analyzer scans the frequecies in the configuration by measuring the amplitude of electromagnetic energy it receives at each frequency in the configuration, and wherein a trace is generated each time the spectrum analyzer completes a single scan of all the frequencies in the configuration; storing at least some of the amplitude measurements from each trace in computer memory; and leaving the spectrum analyzer unattended while it adjusts from scanning the first plurality of frequencies in the first configuration to scanning the first plurality of frequencies in the second configuration.
