【摘要】 5520A多功能校准器,除了对示波器的输入电阻、绝缘性能项目的测量外,该校准器可用作模拟示波器检定的标准器,同时还能满足对数字示波器的一些常用项目的校准。介绍了用多功能校准器校准示波器的方法,并对其测量不确定度进行了评定。更多还原

【Abstract】 Model 5520A Multifunction calibrator, except for tests of input resistance and insulation performance items of oscilloscope, it can also be used as the standard calibrator for analog oscilloscope, and in the mean time it can also meet the calibrations for normal items of digital oscilloscope. Introduction was made to the method to use multifunction calibrator to calibrate oscilloscope and as well as the evaluation to the uncertainty of its measurements.更多还原
