Automotive EMI/EMC Pre-compliance Tests

application note image for Automotive EMI/EMC Pre-compliance Tests

Electromagnetic interference (EMI) regulations are in place throughout the world to provide improved reliability and safety for users of electrical and electronic equipment. The automotive industry and individual automobile manufacturers are required to meet EMI standards specifically for automotive systems.

With the introduction of USB-based real-time spectrum analyzers, pre-compliance EMI testing has become significantly easier and more cost-effective for designers. This application note provides an overview of measurement regulations and EMI pre-compliance procedures. Test setups for both radiated and conducted emissions are shown using the Tektronix RSA306B with EMCVu software.
