摘　　要：为了解决全日制大学本科电子信息类专业学生知识与专业脱节的问题,设计一个高频数控移相器及其检测实验系统。该实验系统是从接收机中多通道相位自动均衡这样一个实际工程应用中提炼而出,以数控移相器为核心,围绕它展开静态、动态检测系统设计。该实验设计合理有效,能够激发学生的兴趣,并且对培养学生电路设计和构建系统的能力、打牢专业基础有一定帮助。Aiming at the problem that the knowledge of students in electronic information profession in full-time university is out of line with their specialties,an experimental system for high-frequency digital phase shifter and its detection is designed.This experimental system is refined from multi-channel phase automatic equalization in receivers,which is an engineering application.The digital phase shifter is taken as the core of the system to carry out the static and dynamic detection system design.This experimental design is reasonable and effective.It can stimulate students′interest,cultivate students′ability of circuit design and system construction,and help the students to lay a solid professional foundation.
