时钟指示时间同步误差的测量

Measurement of Synchronization Error of Clock Indicating Time

时间同步对我们越来越重要,同步时钟应用越来越广泛,同步时钟不可避免会存在同步误差,同步时钟指示时间大于1s的同步误差和PPS脉冲间同步误差测量非常简单,但是时钟指示时间在1s以内的同步误差测量有些棘手,现有资料没有这类同步误差的测量方法,研究探索这类同步误差测量方法,对同步时钟使用和评估有非常积极的意义。

The synchronization of time is very important to us, and the synchronous clock is becoming more and more widely used.When the synchronization error of synchronous clock indicating time is more than 1 s and for the synchronization error between PPS pulse, the measurement is very simple.But when the synchronization error of synchronous clock indicating time is less than 1 s, the measurement is difficult.There is no method for the measurement of such synchronization error in the existing data.It is of great significance to study such synchronization error measurement methods for synchronous clock use and evaluation.
