Overview
Application
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 generates slow transients while the mechanical switch, a typical relay used in the vehicle, generates the fast transients. 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.
Standards
- ISO 7637-2:2004
- ISO 7637-2:2011
Benefits
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.
Three-in-one
CISPR 16-1-2). A second switch is used to switch in the internal 50ohm termination resistor as required.
The AN 200N100 is fully adapted to the various test requirements and shows the typical impedance characteristics according to the different standards.
