GPIB通信在电容测试仪表校准中的应用

GPIB Communication Application for C-V Meter Calibration

安捷伦电容测试仪表(E4980A,4279A)每年需要做年度校准,人工手动校准操作非常复杂且耗时过长。但是运用电容仪表通信协议,年度校准完全可以实现自动化。通过VB编程加GPIB通信的方法编写测控软件,可以实现软件自动发送所有的校准指令,自动判断仪表返回校准数值正确与否,自动保存校准数据为Excel文件同时录入数据库,实现了快速高效的电容测试仪表的校准。

Agilent C-V Meter （E4980A, 4279A） needs yearly calibration. Manual calibration is complex andtime-consuming. However the calibration procedure can be done automatically via Agilent C-V meter protocolcommand. The communication software developed using VB and GP1B is capable of sending calibrationcommand to C-V meter, making automatically judgments, and saving calibration data into database in .xlsxformat. The auto C-V calibration software significantly improves speed and calibration efficiency.
