在被动型原子频标中,由于相位延时及系统驰豫时间的影响,给伺服环路的同步鉴相环节带来不便,进而会影响系统的指标。从整机系统中参与同步鉴相的两路低频方波信号出发,通过综合器模块中的DDS的FSK模式来调整两路方波信号的相位,使其满足同步鉴相的要求,并给出了调整后系统稳定度指标改善的实验结果。

The stability of the passive atomic frequency standard can be influenced by the phase delay and system relaxation time.In the servo loop of the synchronization phase discrimination,we can realize the system locked based on the synchronous pulse signal of low frequency.In this paper,the phases of two square waves are adjusted by FSK mode of DDS,in order to satisfy the requirements of synchronous phase discrimination,and the improved experimental results are list out.
