style="text-indent:25px">隨著現(xiàn)代模擬和數(shù)字技術(shù)的發(fā)展，特別是高速運(yùn)放，微處理器技術(shù)的發(fā)展，現(xiàn)代阻抗測量大都使用自動平衡電橋法。首先由信號源發(fā)生一個一定頻率和幅度的正弦交流信號，這個信號加到被測件DUT上產(chǎn)生電流流到虛地“0V”，由于運(yùn)放輸入電流為零，所以流過DUT的電流完全流過Rr，根據(jù)歐姆定律DUT的阻抗：Z = V1*Rr/V2。因?yàn)檫\(yùn)算放大器虛地功能的引入，使這種測量方法的精度和抗干擾能力產(chǎn)生了質(zhì)的飛躍。當(dāng)然，以上只是一個比較抽象化的原理模型，真正的產(chǎn)品要復(fù)雜的多。貴州lcr電橋價格一般地，lcr儀器定價是根據(jù)頻率準(zhǔn)確度、性能等要素綜合確定的。</p><div

style="text-indent:25px">LCR數(shù)字電橋測試速度100Hz(約4次/秒)與120Hz(約5次/秒)快中慢速度都一樣,*當(dāng)測試頻率為1kHz以上時:快速約16次/秒;中速約9次/秒;慢速約5次/秒.為得到實(shí)際的測量速度,應(yīng)該規(guī)定具體的測量條件,因?yàn)闇y試頻率、速度、元件值的大小、分選方式、顯示方式、測試方式、量程方式等均會影響測量速度.長期不用,請用原始包裝或先包密封塑料袋再用紙箱包裝,儲存在溫度為-10℃~40℃、濕度:≤85%RH的通風(fēng)室內(nèi).若被測件為電容器時,盡管儀器具有專門的抗沖擊電路,通過將被測電容與信號源測試部分相隔離和吸收回路,使得由于電容器的破壞性大幅降低.但從LCR數(shù)字電橋的可靠性和安全性角度來講,應(yīng)先將被測電容器的余電放干凈,再進(jìn)行測試.</p><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(dāng)DUT(Device Under Test)接入電路時，放大器的負(fù)反饋配置自動使得OP輸入端虛地。Vx準(zhǔn)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(jì)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(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(jié)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(jié)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。有了LCR數(shù)字電橋，還需要選擇一款合適的測試夾具才能滿足您的測試需求。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
