Teseq Strip Line 90 Ω

The transversal electromagnetic mode which can be developed in the SL 90 strip line, provides the opportunity for doing EMC testing inside the strip line. The geometrical dimensions having a line impedance of Z = 90 Ω. At the end, the line is matched by a 90 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 narrowband electromagnetic energy: Measurement procedure for components part 5: Strip Line’. The SL 90 allows testing electrical/electronic sub-modules (EUB) and their associated cables. Standards like BMW GS 95002 allow both emission and immunity testing with the strip line. Although emission testing is derived from ISO 11452-5 where the strip line is exclusively used for immunity tests. BMW GS 95002 provides additional hints. The limit line is given as interference voltage level in dμBV.
