示波器标准装置的稳定性考核

Stability testing of oscilloscope standard calibrating apparatus

无论是示波器标准装置的建标还是已建示波器标准装置的复查,稳定性考核是必须完成的一项重要工作,针对示波器标准装置的高频参数和低频参数多、测量范围大、且操作较复杂等现状,从理解计量标准的稳定性概念入手,通过测试实例详细说明示波器标准装置稳定性考核的几种方法、判定准则和注意事项。

Stability testing is a necessary and important process for the standard setting and reviewing testing of oscilloscope standard calibrating apparatus. The oscilloscope standard calibrating apparatus has many high-frequency and low-frequency parameters and large measuring range. It's complex to operate correctly. By understanding the concept of measurement standard stability, it illustrated that several methods, evaluation criteria and precautions of the stability testing of oscilloscope standard calibrating apparatus,in detail.
