1、RE:辐射发射(RE)(100k~2.7G)Radiated Emission :辐射骚扰测试
2、CE:传导干扰CE(conduction emission)(150kHz~108MHz):传导骚扰测试
3、RS:辐射抗扰:射频电磁场辐射抗扰度测试
4、CS:传导抗干扰:射频场感应的传导骚扰抗扰度测试
5、EFT:瞬态脉冲干扰:电快速瞬变脉冲群抗扰度测试
6、DIP:电压跌落:电压暂降,短时中断和电压变化抗扰度测试
7、ESD:静电:静电抗扰度测试
8、Surge:浪涌:抗扰度浪涌(冲击)抗扰度测试
关于RE和RSE的区别:
辐射杂散(简称RSE)是指当移动台与非辐射性纯阻负载相连接或者在接收机状态时,由移动台产生或放大的通过移动台机壳、电源、控制设备、音频各电缆辐射的工作频率外上的发射。
在目前的国际标准中“辐射杂散”基本都将其划分在了射频项目(RF)里面,而国内标准(以YD1032为典型)则将其划分在电磁兼容(EMC)的测试内容内。
从RSE的定义可以看出,RSE测量的不仅仅是发信机发出来的噪声,它覆盖的是整个杂散域,既包含有意发射,也包含EUT中与发信机无关的其它电路的无意发射。3GPP标准颁布以后,RSE测试成为衡量无线产品EMI性能的重要测试。与此同时,不难发现,RE和RSE测试的考察范围存在着重叠。
