TH2819A LCR数字电桥简要说明
TH2819A LCR数字电桥是TH2819的升级换代产品,继承了TH2819操作简便(操作界面全面兼容)、读数准确稳定的特点,体积较之大为减小、外观令人耳目一新、价格低廉。
TH2819A是一种用于对各种电子元件检验的多功能元件测试仪器。可提供20Hz-200kHz的测试频率,频率分辨率达10mHz, 5mV-2V宽范围的测试信号电平,32ms/次的测试速度,既包括TH2819具有的各种测试参数,另提供了直流电阻DCR的测试能力。TH2819A LCR数字电桥器内部可提供1.5V/2V内偏置电压,还可选配可选10V(100mA)及1 A内部直流偏置源及各种外置电感偏流源,使其尤其适用于对各种电感元件的检测。
TH2819A是一种高速度、测试范围宽、6位测试分辨率的阻抗测量仪,可满足生产线质量保证、进货检验及实验室测量要求。
