4TP模拟电感标准器的设计与实现

Design and Performance of 4TP Quasi Inductance Standard

四端对定义在阻抗测量中可以获得很高的测量准确度,商用高准确度4TP阻抗测量仪的应用越来越广泛,文中介绍的4TP模拟电感标准器可用于上述仪器的校准。本文重点介绍了利用RC网络模拟电感值的基本原理,4TP模拟电感标准器的设计计算和实现方法,并用实验数据说明4TP模拟电感标准器的性能稳定可靠。

Four terminal pair （4TP） definition can achieves the highest accuracy in impedance measurement. 4TP commercial LCR meters are available on the market. The application of them is more and more. The quasi inductance standard can be used to calibrate the instruments a- bove. The paper introduce the principle that inductance standard have been design in form of RC network, the method of calculation and perform- ance. The measured data confirm that 4TP quasi inductance standard is stable and dependable
