Test Set for the Measurement of Automotive Transient Emissions as per ISO 7637
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 300 ns semiconductor switch, which is used in most applications, both fast and slow. While, the BS 200N100.1 can be used up to 1300 V, the standard recommends a mechanical switch for transient emissions over 400 V.
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.
