應(yīng)用特點Application Characteristics:
用來測量被試設(shè)備(EUT)在正常工作狀態(tài)下通過電源線、信號/控制線對周圍環(huán)境所產(chǎn)生的傳導干擾是否符合要求。如果干擾信號過大,就會影響整個電網(wǎng)的用電質(zhì)量,從而干擾到其他電器的正常運行。
在實際測試時,受試物在上電期間可能會產(chǎn)生很強的瞬態(tài)信號,可能會沖擊并損壞測試接收機的 RF 輸入端口,因此一般需要在 AMN 和接收機之間串一個能抑制瞬態(tài)信號的脈沖限幅器。如果受試物電流過大(例如大于 400A)或者無法使用 AMN 進行測量時,可以使用 CISPR 16-1-2 規(guī)定的高阻抗電壓探頭進行測量。
