EMC Tests of Electronic Devices and Equipment

Our Testing Possibilities in Detail
Measurement of Emissions

according to the relevant regulations, EN (VDE), VG 95370/373, MIL-STD 461/462

Interfering currents20 Hz up to 400 MHz
Interfering voltages20 Hz up to 100 MHz
Interfering fields 1)0 Hz up to 30 MHz (magn. fields)
10 KHz up to 7 GHz (el.-magn. fields)
Susceptibility Testing

according to the relevant regulations, EN (VDE), VG 95370/373, MIL-STD 461/462

Interference immunity against:

Interfering currents/ Interfering voltages20 Hz up to 400 MHz
Impulsive disturbancesdifferent forms of impulses
(high-energy impulses, bursts)
Interfering currents / Interfering voltages(ESD) Air / Contact discharge
Interfering fields 1)0 Hz up to  3 MHz (magn. fields)
10 KHz up to 1 GHz (el.-magn. fields)

1) Due to the cabin dimensions, field strength tests conforming to standards are only possible according to military standards (VG, MIL-STD). Tests according to EN can be carried out as pre-compliance tests with reduced test distances.
