| 摘 要： | 传统的人工时间同步误差的测量方法存在操作复杂和效率低下的缺点。为解决这些问题,提出一种同步误差的测量方法,该方法基于复杂可编程逻辑器件（CPLD）技术,并利用全球定位系统来测量时间统一系统的同步误差。相对于传统的测量方法,该方法显著提高了同步误差测量的智能化程度,减轻了测试人员的工作量。通过实验,验证了本设计方案的可行性及正确性。

| Abstract: | Traditional manual time-synchronization test methods exhibit many drawbacks, such as complex operations and low efficiency. To overcome these drawbacks, in this paper, we proposed a novel method based on the Complex Programmable Logic Device（CPLD） to measure the synchronization precision of the Time-Uniform system by GPS. Compared with the traditional methods,this method significantly improves the intelligentization of the synchronization precision’s measurement and ease the work loads of testers. Finally,The feasibility and validity of this design were validated through the test by the high-precision oscillograph and the protocol analyzer. |
