src="https://tyunfile.71360.com/UploadFile/ZRX888/637284365304560547/7895297.png"></div><p style="text-indent:25px">LCR測試儀測試原理：Vx與Vr均是矢量電壓表，Rr是理想電阻。LCR測試儀自平衡電橋的意思是：當DUT(Device Under Test)接入電路時，放大器的負反饋配置自動使得OP輸入端虛地。Vx準確測定DUT兩端電壓（DUT的Low電位是0），Vr與Rr測得DUT電流Ix，由此可計算Zx。LCR測試儀提高精度的方法是: 1,Hp,Lp,Hc,Lc盡量接近DUT; 2,減小測試電流Ix的回路面積&磁通量（關鍵是分析Ix，要配合使用Guard與Cable*小化回路面積);3,使用Gurard與Cable構建地平面中斷信號線間的電場連接，雖然會增加信號線的對地電容（對地電容不影響測試結果），但是會減少信號線的互容。Guard與Cable的對地寄生阻抗（Zhg,Zlg) 不影響測試結果，電橋平衡時Zlg的兩端電壓是0，流向Rr的電流不會被Zlg分流，Zhg的分流作用不影響Hp的電壓測量。LCR數(shù)字電橋選配GPIB接口和電腦相連，編寫相應的軟件，可以實現(xiàn)用電腦控制儀器，進行自動測量。lcr電橋的使用</p><p style="text-indent:25px">通過本文的介紹，相信大家對于LCR數(shù)字電橋有了一定的了解。lcr電橋的使用</p><p style="text-indent:25px">LCR數(shù)字電橋操作面板都有“串聯(lián)”和“并聯(lián)”按鍵供用戶選擇，這串聯(lián)和并聯(lián)不是物理連結，而是內(nèi)在計算模式的改變，以改變計算模式得到理想的測試精度。理論上電感正弦波激勵響應電壓超前電流90度，電容電壓落后電流90度。實際測量中由于銅阻和各種損耗的存在，超前或落后都小于90度，這種損耗在測量中以副參數(shù)出現(xiàn)，電感損失角的正切值的倒數(shù)稱品質(zhì)因素Q值。同樣電容損失角的正切值稱損耗因子DF。LCR數(shù)字電橋進行高精度量化，要建立適當?shù)臄?shù)學模型，經(jīng)過一些數(shù)學運算，得到各種參數(shù)值。在整個過程中，把損耗的影響用電阻等效和電感或電容串并聯(lián)。lcr電橋的使用</p><p
