摘　　要：本文设计了一种利用Python编程语言实现的多总线示波器智能检定系统,通过识别品牌型号,智能计算最大带宽、通道数,并通过自动化校准过程,将原本耗时2h的单通道校准时间缩短至12min。同时,为了增加设备的可扩展性,采用了配置文件,使用户可轻松添加新的示波器,且无需编程。此外,对一种新的示波器校准信号的自动校准方法进行探讨,并与检定规程中的方法进行比对。结果表明:该方法无需人工调整设备,且结果更快速、准确、客观。In this paper,an intelligent verification system for multi-bus ascilloscope is designed using Python pro-gramming langunge.By identifying brand models,the maxinum bandwidth and number of channels are calculated intelligently,and the single-channel calibration tine,which originally takes 2h,is shortened to 12min through auto-matic calibration process.At the same time,in order to increase the scalability of the device,a configuration file is used to make it casy for users to add rew oscilloscopes without programming.In adklition,a Tew antomatic calibra-tion method of oscilloscope calibration signal is discussed and compared with the method in the verification regula-tion.The results show that this methodoes not eed o adgusthe sinment mnaly,nd the resuts ae more rapid,accurate and objective.
