摘要
本文采用基于Labview的虚拟仪器技术,设计完成了一套高温超导体R^T曲线虚拟仪器测试系统,通过IEEE488总线对电流源和纳伏表的控制,利用超导体在超导态时的零电阻特性,测量超导样品的超导电性,测量精度高,速度快,测试界面直观、友好。
A set of virtual instrument system based on Labview for measuring the R^T curve of the high temperature superconductor is designed in this paper. The control for the Current Source and nanovoltage meter is realized by the IEEE488 bus. The superconductivity is measured based on the zero resistance characteristics of the superconductor. The measurement is of high precision and of high speed. The man-machine interface is direct and friendly.
