Abstract :
Described in this paper are the results of design of computer-aided frequency synthesizer for millimeter band quasi-optical ESR spectrometer. Adjusting of the output signal frequency is realized using reference digital synthesizer, which is controlled by computer or remote-control unit. The long-time frequency instability is not worse than 2*10-10; the minimal frequency step is 10 Hz. The operating characteristics of the synthesizer are demonstrated at the ESR-spectroscopic test measurements
