EUT Equipment Under Test. Equipment to be tested by test equipment.
Electrostatic
discharge (ESD)
immunity test
A category of immunity test which simulates electrostatic discharge
phenomnon that a charged human body or object discherges to an electronic
product.
Contact discharge
A method of the ESD immunity testing in which the discharge tip of the
discharge gun is kept in contact with the EUT or coupling plane and the
discharge is actuated by the discharge switch of the simulator. It is an
unrealistic phenomenon in nature, but enables the test more reproducible.
Air discharge
A method of the ESD immunity testing in which the discharge tip of the
discharge gun is moved towards the EUT until the tip touches the EUT. It is
closer to natural phenomenon but has an unstable elements since it is
dependet on test enviroment due to discharge in the air.
