Correction of time base error for high speed sampling oscilloscope

In order to improve the accuracy of measurement the correction of time base error of oscilloscope is essential. In this paper we studied time base error. There are three kinds of time base error including time base drift, time base jitter and time base distortion. Reason of time base error causes and the influence for measurement and calibration, the method for correction or compensation were studied. We also had good results as we process the experiment data which proofed the method in this paper were right.
