摘要
介绍了数据采集系统通道间延迟时间差的一种简单实用的评价方法,即正弦波拟合法。讨论了评价过程的误差来源,以及减小其评价误差的几种对策;同时,给出了评价过程的几个典型实验结果。
One simple and useful calibration method to evaluate the delay of channels of data acquisition system is introduced. The sources of errors are described, and some methods for decreasing the uncertainty of calibration results are discussed.
