- 16,5 kV AIR / 10 kV CON discharge
- IEC 61000-4-2 (150 pF / 330 Ohm)
- Predefined tests – Standard and others
- Battery or mains operation
1. Air discharge.
With this method the test generator SESD 216 must be moved to the EUT. The discharge of the high voltage is in the air. The test voltage can be varied from 200V to 16.5000V. The very short rise time of each single pulse generates a wide RF spectrum and interference.
2. Contact discharge.
The discharge electrode with a sharp point is connected to the EUT. The discharge switch is a vacuum relay. This test method reduces the interference of parameters like approach speed, amplitude, humidity and temperature.
The contact discharge is the favourite test method since it is most reproducible. Air discharges are used when contact discharges are not possible – e.g. at plastic housings.
