style="text-indent:25px">直流偏置源和市場(chǎng)上的直流電源一樣嗎？(1)直流偏流源是一個(gè)恒流源，輸出時(shí)呈現(xiàn)的分布電容電感應(yīng)該很小，其大小決定偏流源與LCR測(cè)試的帶寬，而普通市場(chǎng)上的直流電源沒有這些指標(biāo)。(2)若要將市售的直流電源做成偏流源要加很大的電感器，來提高電源本身交流輸出阻抗，該方法在電橋頻率大于10KHZ時(shí)基本不能實(shí)現(xiàn)。直流偏置電流源可以疊加到幾安培？直流偏置電流源TH1772B可以疊加到30安培,TH1773和TH1775不能疊加,TH1776可以疊加到40安培。直流偏置電流源在有些頻率下為何無法清零?交流輸出阻抗頻響不一致，在某些頻率點(diǎn)可能產(chǎn)生諧振。湖北電橋lcr選擇精度高、量程寬、速度快、穩(wěn)定性好是LCR電橋的特點(diǎn)。</p><div

style="text-indent:25px">LCR測(cè)試儀測(cè)試原理：Vx與Vr均是矢量電壓表，Rr是理想電阻。LCR測(cè)試儀自平衡電橋的意思是：當(dāng)DUT(Device Under Test)接入電路時(shí)，放大器的負(fù)反饋配置自動(dòng)使得OP輸入端虛地。Vx準(zhǔn)確測(cè)定DUT兩端電壓（DUT的Low電位是0），Vr與Rr測(cè)得DUT電流Ix，由此可計(jì)算Zx。LCR測(cè)試儀提高精度的方法是: 1,Hp,Lp,Hc,Lc盡量接近DUT; 2,減小測(cè)試電流Ix的回路面積&磁通量（關(guān)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(gòu)建地平面中斷信號(hào)線間的電場(chǎng)連接，雖然會(huì)增加信號(hào)線的對(duì)地電容（對(duì)地電容不影響測(cè)試結(jié)果），但是會(huì)減少信號(hào)線的互容。Guard與Cable的對(duì)地寄生阻抗（Zhg,Zlg) 不影響測(cè)試結(jié)果，電橋平衡時(shí)Zlg的兩端電壓是0，流向Rr的電流不會(huì)被Zlg分流，Zhg的分流作用不影響Hp的電壓測(cè)量。</p><p style="text-indent:25px">對(duì)于LCR數(shù)字電橋的使用來說，正確的選擇所需要的電阻頻率很重要。我們需要知道幾個(gè)選擇的規(guī)則。電容小于2nF，選擇，選擇串聯(lián)1KHz，選用高的測(cè)試信號(hào)可提高測(cè)試精度，同樣能量測(cè)大于1000μF以上電容。電感小于2mH，用串聯(lián)1KHz，選擇高測(cè)試頻率可提高測(cè)試精度。電感大于200H，并聯(lián)，120Hz，選擇低測(cè)試頻率可提高測(cè)試精度。電阻大于等于 1K Ω，選擇并聯(lián)120Hz(100Hz)，選擇低頻減少交流影響，選擇“并聯(lián)”，是因?yàn)榱繙y(cè)過程中出現(xiàn)電抗部份，等效為被測(cè)件并聯(lián)一個(gè)電容呈現(xiàn)的高電抗，用并聯(lián)模式減小這種影響，如果Q＜0.1，已存在小電容影響。經(jīng)濟(jì)實(shí)用型LCR數(shù)字電橋，可以滿足一般的測(cè)試要求。</p><div
