Abstract : The report describes the theory of operation and the construction of three related systems which can be used to measure the frequency of the individual components of a composite signal spectrum. The frequency measurement is made by selectively synchronizing a phaselocked oscillator to each component and counting the output of this 'marker' oscillator. By using the marker oscillator in conjunction with or as an integral part of a spectrum analyzer, a visual indication of the frequency location of the marker oscillator with respect to the other components is obtained. Two of the systems operate in the region of 455 kc while the third tunes 4-30 Mc and is used in conjunction with a 455 kc system to measure the original RF frequency of components that appear in the IF passband of a receiver.
