吉赫宽带电磁场测量与校准系统

A Wide Band Measuring and Calibrating System for Gigaherz Electromagnetic Field

本文介绍采用吉赫横电磁波传输室建立高频宽带电磁场的测量与校准系统。其工作频率为10kHz～1000MHz,场强范围为1μV/m～100V/m,校准不确定度小于1dB。该系统可按国际电磁兼容标准要求进行测试。

-In this paper, a wide band measuring and calibrating system for gigaherz electromagnetic field by using GTEM cell is presented. The range of field strength is from 1μV/m to 100 V/m, the range of working frequency is up to several GHz and the calibration uncertainty of the field is less than 1 dB. The system can he used for the test required according to the related international electromagnetic compatibility standard.
