EM Test test set for the Measurement of Automotive Transient Emissions as per ISO 7637-2
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.

ISO 7637-2:2011
The EM TEST Transient Emission Set consisting of the BS 200N100 electronic switch, the artificial network AN 200N100 and the BSM 200N40 mechanical switch is an easy-to-use, economic and compact solution, fully compliant to ISO 7637-2. Small size of the equipment and short interconnections allow to meet the distances specified by the standard. An optional resistor box RS-Box with shunt resistor is available for transient emission measurements as per ISO 7637-2:2004 and ISO 7637-2:2011. The RS-Box offers the required 40ohm shunt resistor and other demanding shunt resistors values of e.g. 10ohm, 20ohm and 120ohm.
