Abstract : The patent describes a test system where a fundamental signal is sent through a unit to be tested and at the same time this signal is sent around said unit to be tested and shifted a 180 degrees in phase with respect to output of unit. The two signals are then combined to eliminate the fundamental, and the spurious signal is measured by a spectrum analyzer.
