摘　　要：数字通信系统中,时钟抖动是影响通信质量的因素之一,在系统设计、设备研制、工程验收等各环节抖动指标是必须考虑的。本文介绍了通信中常用的抖动概念、分类、度量指标和测试方法,并对时钟设备抖动指标测试进行了描述。最后对抖动测试的发展方向进行了展望。In digital communication systems,clock jitter is one of the factors that affect communication quality,and jitter indicators must be considered in various links such as system design,equipment development,and engineering acceptance.This article introduces the jitter concepts,classifications,metrics and test methods commonly used in communications,and describes the jitter index test of clock equipment.Finally,the development direction of jitter test is prospected.
