Abstract

To solve the frequency aging problem of high-precision quartz crystal oscillator has been one of the most written topics in the international frequency control field. Aging prediction is a significant approach to the process of the long-term aging indicator problem. Aiming at the aging issue of the crystal oscillator, in this paper, we take the SC cut 10MHz OCXO as the aging experimental subject, construct a model by time series analysis method, fit the aging process of the crystal oscillator, predict the development trend, and compensate the accuracy of the crystal oscillator's frequency output with predicted result. The experimental results demonstrate that this model is well-performed in describing the frequency aging process of the quartz oscillator and predicting the frequency aging. Furthermore, verified by simulation, the effect of compensation is evident. The indicator, daily aging rate of crystal oscillator after compensation could reach the level of 10-11.
