Abstract
To analyze the factors of frequency aging in ultra-stable quartz crystal oscillators, a novel system that continuously measures the stability in both resonant frequencies of the resonators and oscillation frequencies has been proposed. Experimental results show that the long-term drift of resonant frequency depends mainly on the amplitude of the crystal driving current and that the aging of the circuit partly affects the aging of oscillation frequency
