脈(mo)(mo)(mo)沖群(qun)(qun)發(fa)生(sheng)(sheng)器抗擾(rao)度(du)試驗，是模擬電(dian)(dian)網(wang)中(zhong)眾多機械(xie)開關(guan)在切換感性負載(zai)時所產生(sheng)(sheng)的干(gan)擾(rao)。這類干(gan)擾(rao)的特點是：成群(qun)(qun)出(chu)現的窄脈(mo)(mo)(mo)沖、脈(mo)(mo)(mo)沖的重(zhong)復頻(pin)率較高（kHz-MHz 級(ji)(ji)）、上升沿陡峭（ns 級(ji)(ji)）單個脈(mo)(mo)(mo)沖的持續時間(jian)短暫（10-100ns 級(ji)(ji)）、幅度(du)達到 kV 級(ji)(ji)。成群(qun)(qun)出(chu)現的窄脈(mo)(mo)(mo)沖可(ke)對半導體器件的結電(dian)(dian)容充電(dian)(dian)，當能量積累(lei)到一定程度(du)后可(ke)引起線路或(huo)設備(bei)出(chu)錯。
電(dian)(dian)(dian)(dian)路(lu)中，諸(zhu)如來自(zi)切換瞬態(tai)過程（切斷感性負(fu)載、繼(ji)電(dian)(dian)(dian)(dian)器觸點彈跳等），通(tong)常會對(dui)(dui)同一電(dian)(dian)(dian)(dian)路(lu)中的(de)(de)其他電(dian)(dian)(dian)(dian)氣和(he)電(dian)(dian)(dian)(dian)子(zi)設備產生(sheng)干(gan)擾(rao)。這(zhe)類干(gan)擾(rao)的(de)(de)特點是(shi)：高幅值、上升時(shi)(shi)間短(duan)、高重復率(lv)和(he)低能量。成群出(chu)現的(de)(de)窄脈沖可(ke)對(dui)(dui)半導體器件的(de)(de)結電(dian)(dian)(dian)(dian)容充電(dian)(dian)(dian)(dian)，當累積到一定程度后可(ke)能引起(qi)電(dian)(dian)(dian)(dian)路(lu)或設備出(chu)錯(cuo)。我(wo)司自(zi)主研發的(de)(de)脈沖群發生(sheng)器為評(ping)估電(dian)(dian)(dian)(dian)氣和(he)電(dian)(dian)(dian)(dian)子(zi)設備的(de)(de)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源端口、信號、控制(zhi)和(he)接地端口在受(shou)到電(dian)(dian)(dian)(dian)快速瞬變脈沖群干(gan)擾(rao)時(shi)(shi)的(de)(de)性能確定一個共(gong)同的(de)(de)能再現的(de)(de)評(ping)定依(yi)據
觸(chu)摸式脈沖(chong)磁場(chang)發(fa)生器(qi)PFM61009TG是針對脈沖(chong)磁場(chang)抗擾度(du)試驗的(de)(de)特點和(he)要(yao)求(qiu)而專門設計的(de)(de)高(gao)可靠性(xing)測試儀器(qi)，產(chan)品(pin)*符(fu)合IEC61000-4-9和(he)GB/T17626.9標準(zhun)的(de)(de)要(yao)求(qiu)，具(ju)有(you)智(zhi)能(neng)化、性(xing)能(neng)穩定、操(cao)作便(bian)捷等(deng)特點。
群脈(mo)沖發生(sheng)器電(dian)容(rong)耦合(he)夾能(neng)與主(zhu)機配合(he)使用，在設備的輸入、輸出、控制線、數據線上疊加干擾，進行系統抗(kang)干擾試驗。
