Electrostatic discharge testing device and electrostatic discharge testing method

Abstract

The invention discloses an electrostatic discharge testing device and an electrostatic discharge testing method. The electrostatic discharge testing device comprises an oscilloscope and a coaxial line, wherein the coaxial line is used for realizing connection between the oscilloscope and equipment to be tested, and the oscilloscope is used for acquiring electric signals generated by the equipment to be tested in the electrostatic discharge testing process and performing graphical identification on the electric signals. On the basis, the energy of electrostatic discharge in the testing process can be quantified, so that the testing personnel are facilitated to select an ESD device purposefully.

Description

technical field [0001] The invention relates to the field of electrostatic discharge (Electro-Static discharge, ESD) testing, in particular to an electrostatic discharge testing device and an electrostatic discharge testing method. Background technique [0002] In order to achieve better convenience and expandability, most of the existing electronic devices are equipped with multiple external ports, such as USB Port (Universal Serial Bus Interface). Because such electronic devices support the hot-swappable function, the electronic devices may be attacked by electrostatic discharge generated by users plugging and unplugging external devices during system operation, resulting in system downtime or data loss. Therefore, today's electronic equipment must pass the electrostatic discharge test. [0003] In the existing electrostatic discharge test process, ESD devices of different standards are generally selected to perform electrostatic discharge on the equipment under test (EUT...
