Remove the time base drift of sampling oscilloscope

The time base drift is a key factor that influences the sampling oscilloscope to measure the high speed pulse signal precisely, so time base drift must be removed as far as possible. Cross-correlation algorithm is an alternative method to remove time base drift effectively. First, this paper does computer simulation, then use the algorithm to do research on the original data that is collected when establishing national pulse parameters primary standard. Both the results of simulation and the research show that the cross-correlation algorithm can remove the time drift effectively.
