Abstract:
The present invention relates to an apparatus and method used to measure and identify sources of communications interference. In one embodiment a test instrument includes multiple receivers designed for reception of radiated radio signals in free space. The resulting measured signals are processed to determine if there is a mathematical and/or timing relationship between the parent transmitter(s) suspected of causing the interference, and the actual measured interference in the spectrum being evaluated, and providing a ranked list of possible interferers.
