航天机电集团公司２０３所采用多种方法相互补充和相互验证，建立了数字通信信号大宽范围抖动的计量标准，并通过了部级鉴定，达到了国际同类标准的先进水平。数字通信信号抖动计量标准选用外调制源和外时钟方法组成高稳定、高准确度的抖动标准。通过对数字信号抖动特性在时域
Aerospace Electromechanical Group 203 using a variety of methods complement each other and mutual authentication, the establishment of a wide range of digital communications signal jitter measurement standards, and passed the ministerial identification, reached the international advanced level of similar standards. Digital communication signal jitter measurement standard selection of external modulation source and external clock method composed of high stability, high accuracy jitter standards. Jitter characteristics over time in digital signals
