CISPR 11CISPR 32 等标准规定的工科医(ISM)设备和信息技术(ITE)设备,需要在开阔场或电波暗室进行30MHz以上的辐射发射测试

结构及特点

测试配置布置图:

  主要测试设备:接收机、EMI接收天线、前置放大器、EMC测试软件等

测试环境:电波暗室

使用环境

电源:380V±10%   50/60Hz

环境温度: 5℃+40℃,周围不应有高浓度粉尘、腐蚀性气体和易燃易爆气氛存在

主要性能指标

主要测试设备

EMI接收机、接收天线、前置放大器、测试软件等

测试环境

电波暗室

测量距离

是指EUT*接近天线的一点与天线中心在地面上投影间的距离。优先采用10米法,可选3米法

天线高度

天线距离地面的高度应在规定的范围内变化,以便获得直射波和反射波同相位时会出现的*大读数。对于测量距离≤10米时,天线高度*好在1~4米间变化。

频率范围

30MHz-6GHz
