More information

EM Test Transient Emission Set

The measurement of automotive transient emissions as per ISO 7637-2 requires an electronic switch, a mechancical switch and an artificial network.
The electronic switch is a repeatable, calibrated 300ns semiconductor switch, which is used in most applications, both fast and slow.

While, the BS 200N100.1 can be used up to 1300V, the standard recommends a mechanical switch for transient emissions over 400V.

The artifical network represents the typical impedance of the wiring harness. The AN 200N100 is designed to meet the requirements of ISO 7637-2, CISPR 25 / ISO 11452-4 and CISPR 16-1-2 and can be switched accordingly.
