摘　　要：该文结合本科生毕业设计“PDH／SDH数字传输分析仪的PCM通信编码”的实践过程，实现了PDH／SDH数字传输分析仪应用于PCM网络的误码和抖动等相关物理量的通信网络在线测量实验项目。采用数字传输分析仪和示波器组成的实验系统，开发出在PCM光纤通信中普遍应用的AMI码和HDB。码的编码实验。通过对数字分析仪器的实验开发，不仅使学生完成了毕业设计论文，更重要的是通过实验活动加深了学生对先进仪器的使用、及学生在教学科研中的创新能力的锻炼，同时发挥了学生在创新实验研究中的作用，增强了参与科学研究的信心，熟悉和掌握了PCM通信编码理论及技术。该实验为本科生的专业物理实验课程提供了一个新的实验项目。A new experiment item of ＂Communication codes of PCM on digital transmission analyzer of PDH/SDH＂ was finished in practical process of bachelor thesis. The parameters of error code and tremble have been detected in experiment by applying of digital transmission analyzer of PDH/SDH in PCM web. The coded experiment of AMI and HDB3 has been obtained in optical fiber communication of PCM using the experiment system of consisting of the digital transmission of PDH/SDH and oscillograph. The improving and cultivating of students with knowledge structure, ability training, scientific idea, and resolving problem are important by the experiment exploitation and design in practice teaching process. The student not only finished the bachelor thesis, but joined experiment actively by themselves. At the same time the confidence of scientific research of the students has been enhanced and a new experiment item for specialized physics experiment of undergraduate was improved.
