针对新颁布的《GJB 7691-2012数字示波器检定规程》中的时基检定方法二在实际检定中受限的问题，在深入分析研究信号混叠理论基础上，对该方法中的频率设置及相应的时基相对误差的计算公式提出不同看法，并通过实验对比验证提出修订建议，供规程修订人员和检定人员参考。

One problem exists in the newly issued document GJB7691-2012 Digital Oscilloscope Verification Regula-tion that the second time-based verification method has its limitations in the actual verification work. To solve this problem,the paper put forward a different opinion on the frequency setting and corresponding time-base relative er-ror calculation formula in the method on the basis of the in-depth analysis of the signal aliasing theory. After experi-mental comparison and verification,proposed amendments were madeto provide reference for the regulation revision and verification personnel.
