摘要

A new numerical model of a short-term stability measuring systemnof quartz crystal resonators is presented. It is based on the phasenbridge method using a pair of resonators driven by a low-noise source.nThe output signal, obtained with a phase detector, is proportional tonthe phase difference introduced by the resonators. The numericalntransfer function of each bridge path is given by the model. The outputnspectral density of the phase fluctuations is computed from thesentransfer functions and the numerical approximation of the low-noisensource. The model was applied to third overtone, SC-cut, 10 MHz BVAnquartz crystal resonators. It enables the rejection of the source noisenversus the resonant frequency of quartz crystal resonators to benquantified
