The transversal electromagnetic mode which can be developped in the SL 50 strip line, provides the opportunity for doing EMC testing inside the strip line. The geometrical dimensions having a line impedance of Z = 50 Ω. At the end is required a 50 Ω termination.
Typical for this strip line is the low power request for high field strength values. The strip line is specified in ISO 11452-5 ‘Road Vehicles electrical disturbances through radiated narrow-band electromagnetic energy: Measurement procedure for components part 5: Strip Line’. The SL 50 allows testing electrical/electronic sub modules (EUB) and their associated cables.
