| - | The electrostatic discharge (ESD) immunity test emulates the discharges of tens of nanoseconds duration directly on the electronic components. Two discharge methods are used: Contact Discharge and Air Discharge. Contact discharge includes discharge to the conductive surfaces of the EUT. (An ESD test generator is used with a “sharp point” to make direct connection to the EUT (pin) for Contact ESD testing. A “round tip” is added to the generator and is brought close to the EUT (pin) to trigger a spark for Air-Gap ESD testing. | + | The electrostatic discharge (ESD) immunity test emulates the discharges of tens of nanoseconds duration directly on the electronic components.

| - | There are two methods of applying the discharges, direct and indirect. Direct application involves direct contact to the conductive surfaces and coupling planes. Indirect application involves air discharge at insulating surfaces. The EUT is exposed to at least 20 discharges at each rating for each type of discharge, 10 each at negative and positive polarity. The discharges are repeated at a rate of one discharge per second. | + | There are two methods of applying the discharges, direct and indirect.

| - | The test setup consists of a nonconductive table with a height of 0.8 m, standing on the ground reference plane. A 1.6 m × 0.8 m horizontal coupling plane (HCP) is placed on the table. The EUT and its cable are isolated from the coupling plane by an insulating mat that is 0.5 mm thick. | + | The test setup consists of a nonconductive table with a height of 0.8 m, standing on the ground reference plane.

| The contact discharges are applied to the IO_P and IO_N terminal screws of the AD74115H output terminal block P21.
