摘　　要：介绍现阶段的标准秒脉冲的产生及同步原理,分析了相位调整原理。针对常用相位调整技术精度不高的缺点,提出了一种基于AD9852的精密相位微调技术,给出了硬件和软件实现方案。通过理论分析,采用这种方法的相位调整精度理论优于10ps量级。The generating and synchronization principle of standard pulse-per-second（pps） is introduced in this paper, then the phase regulation principle is analyzed. In allusion to the general phase regulation technique, there is insufficiency in precision , we give a precision phase micro regulation method based on AD9852, and present the implement scheme of hardware and software. This technique can make the precision of phase regulation excel 10ps level by theoretical analysis.
