Statistical mathematical model of the quartz oscillator dynamic modulation characteristics, which takes into account of frequency control circuit parameters of the basic and anharmonic channels has been obtained. The quartz oscillator circuit type and frequency control circuit fluctuation parameters are also considered in model. Obtained model is represented as the nonlinear functional transformations of the narrow-band stochastic process. Obtained formulae allows more accurate and complete calculation of amplitude-frequency and phase-frequency dynamic modulation characteristics of quartz oscillator.
