The transversal electromagnetic mode which can developed 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.
The SL 50 consists of two parallel metal plates. The EUT is arranged in the middle between these plates. The largest outer dimension of the EUT should not be more than 1/3 of the plate distance. The ground is on the lower plate and the isolated upper plate is supplied with RF energy. Between the plates, an electromagnetic field will be established. A typical test configuration consists of signal generator, power amplifiers, power meters and SL 50. To avoid interactions with the environment, the test should be run in an anechoic test chamber.
