Fritz K Weinert: Closed loop for automatic substitution of a signal of equal amplitude. Weinschel Engineering Company, William D Hall, Geoffrey R Myers, July 25, 1978: US04103223 (5 worldwide citation)

A device for testing the accuracy of an attenuator, over a range of frequencies from 1 to 18 GHz, for example, and having a first variable frequency signal generator which passes its output through the attenuator. The resulting output signal, and a local oscillator/mixer combination produce an IF si ...
