FIELD: measuring equipment. ^ SUBSTANCE: method includes measuring instant average frequency of harmonic oscillations selected in couples, determining dispersion of frequency of researched generator, calculation of relative non-stability of frequency of researched oscillation. In device for measuring non-stability of frequency of researched generator three mixers are inserted, three amplitude detectors and three analog-digital converters, while outputs of generators are in couples connected to inputs of mixers, outputs of which are connected to inputs of amplitude detectors, outputs of which through analog-digital converters are connected to appropriate inputs of processor, to output of which device for recording measurement results is connected. ^ EFFECT: higher precision, higher efficiency. ^ 2 cl, 2 dwg |
