Electrostatic test method for simulating practical service environment of product and neighboring equipment simulator

Abstract

The invention discloses an electrostatic test method for simulating a practical service environment of a product and a neighboring equipment simulator. The method comprises the following steps of: connecting tested equipment with the neighboring equipment simulator through a connecting cable; applying static electricity to the neighboring equipment simulator; and performing electrostatic test on the tested equipment, wherein the neighboring equipment simulator comprises an analog power supply, a jumper module and a PCB (Printed Circuit Board), wherein the analog power supply is connected witha protective ground (PGND) and a ground (GND), the jumper module is connected with the GND and the PGND, and the PCB is connected with the PGND. The neighboring equipment simulator is connected with the tested equipment through the cable, the jumper module in the neighboring equipment simulator is reasonably set, and the power supply and the PCB are connected with the GND and the PGND, so that the electrostatic problem of communication products in practical service during cable connection can be simulated; and the scheme is simple to design, does not consume much equipment, meanwhile, can be used for conveniently and effectively testing the electrostatic problem of the neighboring equipment and the tested equipment, and improves the electrostatic test effect.

Description

technical field [0001] The invention relates to static electricity testing technology of communication products, in particular to a static electricity testing method and an adjacent device simulator for simulating the actual use environment of the product. Background technique [0002] In the operating environment of communication products, the human body or some equipment are easily charged with static electricity. When an object charged with static electricity discharges the equipment, it may cause equipment damage and system disorder. The electrostatic test of the equipment can evaluate the anti-static ability of the equipment and find out the problems of the equipment in the case of electrostatic discharge. Electrostatic testing of communication products refers to the use of electrostatic generators to conduct electrostatic discharge on the equipment under test in accordance with the environment and equipment specified in the standard to evaluate the performance of elec...

AI Technical Summary

Problems solved by technology

The above electrostatic test method cannot test the impact on the device under test when the adjacent device is connected with the device under test

[0005] If a real neighboring device is used for electrostatic testing, there are the following disadvantages: 1. In most cases, multiple neighboring devices of different types are required to fully list the connection relationship of the device under test, and the test will consume a lot of time and energy. and device resources

2. Although the connectors of some devices are the same, the connection of the internal signal lines is different, so it is easy to miss the test

[0006] Therefore, the electrostatic test method in the prior art cannot effectively test the static electricity when the adjacent equipment is connected to the device under test by a cable, or there is a problem that it consumes a lot of equipment resources and time and energy, and cannot easily and effectively conduct electrostatic testing.
