摘要
本文阐述ＭＥ５２０Ｂ测试仪在光缆数字通信传输系统中的应用，它具有测试误码性能和抖动性能的作用，可测出长期平均误码率、降级分、误码秒、严重误码秒等指标，并可打印出结果。
his paper expounds the applications of the ME520B Recorder in the transmission system of the optical cable digital communication. By using the Recorder which has the functions of testing the behavior of the error code and the jump grading, the following indexes may be obtained: average percentage of error code in certain long period, degradation in minute(DM), error code in second (ES), serious error code in second (SES),etc. The testing results may be printed out also by the Recorder.
