| 摘 要： | 时频终端不仅需要给出与标准时间同步的时间信息,还要输出与时间信息的秒前沿同步的采样脉冲信号,而且更重要的是对同步的保持。结合时频终端的同步原理和同步精度,详细分析了影响时频终端同步能力的因素,讲述了频率准确度和频率漂移率的测量方法,为确保系统长时间保持同步提供了重要依据。

| Abstract: | Not only gives the time-frequency terminal time synchronization with standard time information, but also output sampling pulse signal, which keep pace with the time information of the second edge. to maintain synchronization is the key point. In this paper, based on the time-frequency terminal synchronization principle and synchronization accuracy, we give a detailed analysis of the factors affecting synchronizability of the time-frequency terminal, and describe the measurement methods for the accuracy of frequency and frequency drift rate. it provides an important basis to ensure that the system keep pace for a long time. |
