ONYX Electrostatic Discharge Simulator
2 Description
2.1 Overview
Any electrical equipment can be subject to electrostatic discharges from human operators or from adjacent objects.
The electrostatic discharge simulator ONYX, reproduces this phenomenon to evaluate the performance of electrical
and electronic equipment.
There are specific test requirements that must be satisfied when conducting ESD testing. These are noted in some
detail in IEC/EN 61000-4-2, ISO 10605 and other standards.
Because of its modular design, ONYX can be adapted quickly and easily to perform testing to any ESD standard.
All ESD testing should ideally be conducted in a Faraday cage or other suitable enclosure.
For small EUT's, a test table constructed only of wood must be used, This is covered with a metallic horizontal
coupling plane which in turn is connected to a ground reference plane by 2 x 470 kOhm resistors.
The EUT should be mounted above the horizontal coupling plane on an isolation plate of 0.5mm thickness.
Vertical coupling planes are to be used to inject an ESD field into all four faces of an EUT.
Larger floor standing equipment must be treated in a similar way but have an isolation plate of 0.1 m.
