Timing pulses are used for time and phase synchronization in many applications such as telecommunication networks and timing laboratories. These signals could not perform this task efficiently or accurately if the time delay added by the cables they are passing through were unknown. This article shows that cable delay not only depends on the cable length but also on the specifications of the signal passing through it. The article provides an overview on the international classifications of time measurements and where cable delay measurements are allocated. Then, the problems encountered in a previous international comparison in cable delay measurement is explored. The results of measuring three cables were connected to the results of the international comparison to verify the sources of these deficiencies. The results are discussed and the main parameters that degrade the accuracy of cable delay measurement are determined. Finally, a possible solution is proposed.

通过同轴电缆的定时脉冲

定时脉冲用于许多应用中的时间和相位同步，例如电信网络和定时实验室。如果它们通过的电缆增加的时间延迟未知，这些信号就无法有效或准确地执行此任务。本文表明电缆延迟不仅取决于电缆长度，还取决于通过它的信号的规格。本文概述了时间测量的国际分类以及电缆延迟测量的分配情况。然后，探讨了以前国际比较电缆延迟测量中遇到的问题。将三根电缆的测量结果与国际比较的结果联系起来，以验证这些缺陷的来源。讨论了结果，并确定了降低电缆延迟测量精度的主要参数。最后，提出了一个可能的解决方案。
