应用特点:
用来测量被试设备(eut)在正常工作状态下通过电源线、信号/控制线对周围环境所产生的传导干扰是否符合要求。如果干扰信号过大,就会影响整个电网的用电质量,从而干扰到其他电器的正常运行。在实际测试时,受试物在上电期间可能会产生很强的瞬态信号,可能会冲击并损坏测试接收机的 rf 输入端口,因此一般需要在 amn 和接收机之间串一个能抑制瞬态信号的脉冲限幅器。如果受试物电流过大(例如大于 400a)或者无法使用 amn 进行测量时,可以使用 cispr 16-1-2 规定的高阻抗电压探头进行测量。
测试配置布置图:
主要测试设备:接收机、人工电源网络、电压探头、emc测试软件等
测试环境:屏蔽室
