Comparison of Emissions from a Transmission Line on a CISPR 25 Bench Setup and Test Vehicle

Abstract

Compliance with radiated emission requirements is one of the biggest challenges faced by the automotive industry. The CISPR 25 bench test is one of the initial test methods that can help the industry to estimate the emissions in the real vehicle but this is hampered by lack of strong correlation. In this paper, a one tenth scale model approach is used to observe the behavior of emissions from a simple transmission line source placed first on a test bench and later in a vehicle.
