簡(jian)要介(jie)紹

 ■ TH2828/TH2828A/TH2828S是(shi)采用(yong)當前(qian)zui先進的(de)(de)(de)(de)自動平(ping)衡電橋原理(li)研制(zhi)成功的(de)(de)(de)(de)新一(yi)代阻(zu)抗(kang)測(ce)(ce)試(shi)(shi)(shi)(shi)儀(yi)(yi)器，其0.05%的(de)(de)(de)(de)基本精度、20Hz—1MHz的(de)(de)(de)(de)頻率范圍及高達100MΩ的(de)(de)(de)(de)阻(zu)抗(kang)測(ce)(ce)試(shi)(shi)(shi)(shi)范圍可以滿足元件(jian)與材料的(de)(de)(de)(de)一(yi)切(qie)測(ce)(ce)量(liang)要(yao)求，特別有利于測(ce)(ce)量(liang)低(di)D電容器和高Q電感器的(de)(de)(de)(de)測(ce)(ce)量(liang)。其支持20V交流(liu)測(ce)(ce)試(shi)(shi)(shi)(shi)信號和40V直流(liu)偏置(zhi)的(de)(de)(de)(de)高功率測(ce)(ce)試(shi)(shi)(shi)(shi)條件(jian)及列表掃描能(neng)力(li)將有利于用(yong)戶擴展元件(jian)評價的(de)(de)(de)(de)能(neng)力(li)。四(si)端(duan)對的(de)(de)(de)(de)端(duan)口(kou)配置(zhi)方(fang)式可有效消除測(ce)(ce)試(shi)(shi)(shi)(shi)線電磁(ci)耦合的(de)(de)(de)(de)影響，將低(di)阻(zu)抗(kang)測(ce)(ce)試(shi)(shi)(shi)(shi)能(neng)力(li)的(de)(de)(de)(de)下限比常規五端(duan)配置(zhi)的(de)(de)(de)(de)儀(yi)(yi)器向下擴展了十倍。
