This paper shows that in this new frequency standard system the multiplication is made by synchronizing oscillation, which is achieved by quenching a microwave oscillator with a standard quartz-crystal oscillator. The output frequency spectrum of this synchronizing oscillator includes only integral multiple frequencies of a quartz-crystal oscillator. Each spectrum can be utilized as standard frequencies. Theoretical calculations and experimental results are also described here. And to avoid the influence of noise voltage on the build-up of the quenching control microwave oscillator, the double modulation system is used, which is controlled and intermitted simultaneously by both f1 voltage (output of the low frequency standard) and n1 f1 voltage (n1 is an integer). By this double modulation method we can understand that the build-up and the stop of the microwave oscillation are exactly controlled by the constant phase of the waves from the standard generator, and also the experimental results of this are described. As an application of this new system, a method of precise frequency measurement is also described.
