摘要

本文构建了基于光脉冲源的示波器校准系统，用标准脉冲法实现了对宽带取样示波器Agilent 86100C的70GHz取样模块86118A的校准.在校准实现过程中，首次综合研究了三种时基误差对校准结果的影响，并采用互相关算法去除时基漂移，最小二乘法修正时基失真，利用反卷积去除时基抖动.实验结果表明，本文方法实现了对70GHz宽带取样示波器的校准，有效地去除了时基误差，满足校准精度的要求.

Abstract

This paper constructed a calibration system of oscilloscope based on the optical pulse source. The 70GHz sampling module 86118A of Agilent 86100C was calibrated based on optical pulse source using the standard pulse method. In the calibration process

the influences on calibration results of three kinds of time base errors were researched for the first time

e. g.

time base drift was removed using a cross-correlation algorithm

time base distortion was corrected using the least squares method

and jitter was removed by using PDF deconvolution. Experiment results showed that calibration of 70GHz broadband oscilloscope was realized

the time base errors could be effectively removed by this method

and the accuracy of the calibration was satisfied.
