摘要
在横电磁波室(GTEMCell)内测量辐射干扰,IEC标准61000-4-20中要求EUT(待测设备)翻转到不同的方位。结合GTEMCell内测试转台的结构,本文采用单片机AT89C51设计转台的自动控制系统,使EUT能借助该转台,自动翻转到IEC61000-4-20中规定的测试位置。
The implementation of EMC test requires the position of EUT to be changed to several different orientations according to IEC Standard 61000-4-20. Taking stock of the structure of rotary testing plate in GTEM cell and the required orientation of EUT, the article described the design of the automatic control system, which uses AT89C51 as controller, of rotary testing plate. The system can change the position of EUT to all required orientations automatically in accordance with IEC Standard 61000-4-20.
