基于MET/CAL的数字示波器自动校准系统

Auto-Calibration System base on MET/CAL for Digital Oscilloscope

摘要:

福禄克公司旗下自动测试软件平台MET/CAL是一款集资产管理、编辑校准程序及运行校准程序于一体的功能强大的自动化测试平台,为了充分应用该平台、编制符合实验室要求及操作步骤的示波器自动测试程序,开发了基于MET/CAL的数字示波器的自动校准系统。主要介绍了MET/CAL平台以及功能选择代码(Functional Select Code, FSC),阐述了系统硬件的搭建与构成以及系统软件的开发要点,软件部分重点介绍了仪器识别模块、系统设置模块、测试项目选择模块、校准过程模块的编制和实现方法。最终通过自动测试结果与手动测试结果的比对验证了系统的准确性和可靠性,证明该系统完全满足预期使用要求。

Abstract:

The MET/CAL platform, produced by Fluke, is a powerful auto calibration platform, which is consist of asset management, program editor and runtime. To make the best of MET/CAL and to complete the auto-calibration for digital oscilloscope, the auto-calibration for digital oscilloscope base on MET/CAL platform was developed. This Article gave a introduction of the MET/CAL environment and Functional Select Code (FSC), details the hardware of the system and the development process of the software, especially focus on the models such as instrument identity, system setup, selection of calibration items, calibration process. In the end, the system’s accuracy and reliability can be verified by compare between auto-calibration and manual operation in results and uncertainty.
