试样范围、用途、原理、结构及使用环境 |
|
试样及限制 |
工科医(ISM)设备和信息技术(ITE)设备 |
试验用途 |
用于测试EUT辐射发射 |
测试原理 |
CISPR 11、CISPR 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米~4米间变化。 |
频率范围 |
30MHz-6GHz |
