Automotive electronics EMC (electromagnetic compatibility) testing capability refers to the ability to evaluate the performance of automotive electronic equipment in the electromagnetic environment. This includes ensuring that automotive electronics do not cause excessive electromagnetic interference (EMI) to other devices during normal operation and are also resistant to external electromagnetic interference (EMS). Automotive electronics EMC testing capabilities are an important part of automotive safety and reliability. Especially under the current trend of intelligence, networking, and electrification in the automotive industry, EMC testing has become even more important.
Key components of automotive electronics EMC testing
1.EMI test
Evaluate the level of electromagnetic interference generated by automotive electronic equipment to ensure that it does not cause interference to other devices or systems. This includes radiated emission testing and conducted emission testing.
2.EMS test
Evaluate the performance and stability of automotive electronic equipment when subjected to external electromagnetic interference. This includes radiated immunity testing, conducted immunity testing, electrostatic discharge immunity testing, etc.
