搜索(EMC)人工電源網(wǎng)絡(luò)計量測試方法
2017-03-24 by:CAE仿真在線 來源:互聯(lián)網(wǎng)
1. 概述
在EMC測試系統(tǒng)中,除了核心測試儀器如接收機(jī)和信號發(fā)生器等,還有許多系統(tǒng)設(shè)備。例如人工電源網(wǎng)絡(luò)、其它EMI和EMS網(wǎng)絡(luò)、電流鉗、放大器、電纜、連接器以及暗室等等。
本方案闡述人工電源網(wǎng)絡(luò)的計量和校準(zhǔn)方法。
在CISPR16中,規(guī)定了人工電源網(wǎng)絡(luò)(AMN/ LISN)的詳細(xì)校準(zhǔn)方法,細(xì)化到每一個測試項目和步驟。考慮到連接的復(fù)雜性和EMC測試人員對矢量網(wǎng)絡(luò)分析儀的了解程度,LISN校準(zhǔn)自動測試系統(tǒng)是最佳選擇。
