Abstract

A Cable Discharge Event (CDE) is an electrostatic discharge between a cable and a connector. CDEs occur on unshielded Ethernet based communication interfaces and inject currents into the pins directly [1-3]. The charging processes are in general understood; however, the discharge processes are complicated due to the number of pins involved and their connections to a system. Based on an understanding of the factors which determine the severity of a CDE, this article describes how to setup a variety of repeatable CDE tests and how to analyze the measurement results.

以太网电缆放电事件(CDE)测试和测量系统
CDE (Cable Discharge Event)是指线缆与连接器之间发生的静电放电事件。cde发生在基于非屏蔽以太网的通信接口上,并直接向引脚注入电流[1-3]。充电过程一般是可以理解的;然而,由于涉及的引脚数量及其与系统的连接,放电过程是复杂的。基于对决定CDE严重程度的因素的理解,本文描述了如何设置各种可重复的CDE测试以及如何分析测量结果。
