HIGH FREQUENCY INTERFERENCE SIMULATOR AND METHOD OF IDENTIFYING CAUSATION OF UNDESIRED NON-LINEAR INTERMODULATION INTERFERENCE

摘要

The primary causation of undesired non-linear intermodulation interference developed from a plurality of known radio frequency sources is determined by the method and process of generating commensurate derivative signals from each of the known radio frequency sources, non-linearly amplifying and mixing the derivative signals to produce composite signals containing spectrally expanded frequencies, separating the frequency components of the composite signals for indicating the amplitude of each component, and then separately disconnecting each derivation signal in turn to identify which of the plurality of known radio frequency sources causes the unwanted intermodulation interference at a particular selected frequency.
