摘　　要：针对示波器校准仪校准项目多、速度慢、效率低的突出问题,基于C#编程语言开展了示波器校准仪高效校准技术研究,采用visual studio为开发工具集,以3458A数字多用表和DSOS604A数字示波器等为标准器,通过GPIB与USB等通讯接口实现对各仪器之间的程控功能。按照JJG 278-2002《示波器校准仪检定规程》的要求完成直流校准电压、方波校准电压、时标、稳幅正弦信号和瞬态参数等项目的自动校准开发。实验结果表明,采用自动校准方法校准示波器校准仪的总耗时仅为23min,仅为手动校准的1/8,校准效率明显提升。Aiming at the problems of many calibration items,slow speed and low efficiency of calibrating oscilloscope calibrator,the research on efficient calibration technology of oscilloscope calibrator is carried out based on C#programming language.Visual studio is used as the development tool set,3458 A digital multimeter and DSOS604 A digital oscilloscope are used as calibrators,and the program-controlled functions between instruments are realized through GPIB,USB and other communication interfaces.According to the requirements of JJG 278-2002"Verification Regulation of Oscilloscope Calibrator",the automatic calibration of DC calibration voltage,square wave calibration voltage,time scale,amplitude stabilized and transient parameters is completed.The experimental results show that the total time of using automatic calibration method to calibrate oscilloscope calibrator is only 23 minutes,which is only 1/8 of manual calibration,and the calibration efficiency is significantly improved.
