摘　　要：时基失真是高速取样示波器取样操作时容易出现的一种误差,在这个误差的影响下会使得取样数值出现坡检查,特别是对于精密仪器的测量来说,在时基失真的情况下会影响到最终的测量结果。为此,文章在阐述时基失真出现原理和时基失真修正算法的基础上,通过开展失真数据的仿真实验分析来对宽带取样示波器时基误差补偿问题进行探究,旨在能够提升国家脉冲参数基准的精准度。Time-based distortion is an error prone to high-speed sampling oscilloscope sampling operation.Under the influence of this error,the sampling value appears in slope inspection,especially for the measurement of precision instruments,and the final measurement results will be affected by the time-base distortion.Therefore,on the basis of the principle of temporal distortion and the temporal distortion correction algorithm,the base error compensation of distortion data,aiming to improve the accuracy of the national pulse parameter benchmark.
