There are many hazardous electrical events in the environment that can have adverse effects on the systems of a vehicle, causing potentially unsafe situations. To protect against these events, automobile manufacturers have developed electromagnetic compatibility (EMC) standards to test electronic components and whole vehicles. This application note delves into the test specifications (from General Motors and Ford) for testing automobiles that may be exposed to an L-band or S-band radar pulse, and introduces testing instrumentation to help address those testing requirements.
