摘要

利用虚拟仪器技术LabVIEW建立了一套可靠、有效的SSRF数字电源中高精密DCCT（DC current transducer）的线性度测试系统

实现了仪器控制和数据采集与记录。软件设计通过GPIB接口进行通讯

友好的人机界面能够方便地进行数字电源DCCT线性度测控

并显示即时的电流值

同时通过RS232控制高精度大电流稳流电源开关与电流输出。Excel格式数据存储通过该软件完成

得出线性度

并为进一步分析DCCT性能提供依据。

Abstract

Based on virtual instrumentation

a reliable and effective test platform

performing instrument control

data acquisition and data recording

has been established to evaluate linearity of high performance DCCT （DC current transducer） for digital power supply at Shanghai Synchrotron Radiation Facility （SSRF）.The software in LabVIEW language was developed to perform computer communication via serial communication （RS232） and GPIB

providing a friendly user interface to the linearity test platform.This makes it easy to test the linearity and control power on or off and current output of high-precision and high-current DC constant current output power supply.The experimental data

stored in an EXCEL file

can be processed to obtain DCCT linearity

and provide basis to further analyze DCCT performance in the future.
