数字示波器检定规程中时基检定方法探讨
Discussion on Time-Base Vertification in Digital Oscilloscope Vertification Regulation
Aiming at the problem in the work of limited verification wih the newly issued document GJB7691-2012 Digital Oscilloscope Vertification Regulation,on the basis of in-depth analysis of the theory of signal aliasing,a question is raised in frequency setting and time-base relative error calculation formula.After experimental verification, a suggestion is proposed to privide reference for the regulation revidion and vertification personnel.
