Automotive

The automotive industry has a long and well-documented history of electromagnetic compatibility (EMC) testing, driven by the early introduction of electronic fuel injection (EFI) systems where electromagnetic interference (EMI) issues were first identified. These early challenges established the foundation for today’s stringent automotive EMC standards, ensuring vehicle safety, functional reliability, and regulatory compliance.

As vehicle electronics expanded to include advanced driver assistance systems (ADAS), infotainment, and networked control units, the importance of automotive EMI/EMC compliance testing increased significantly. The rapid growth of electric vehicles (EVs) and hybrid electric vehicles (HEVs) has raised the bar further, introducing high-voltage power electronics, fast switching inverters, traction motors, and high-current cabling—each a major source of conducted and radiated emissions.

This evolution has driven continuous updates to automotive EMC test requirements, often pushing standards to adapt to emerging technologies. International and regional standards bodies such as ISO, CISPR, SAE, and JASO define baseline EMC test methods, while individual OEMs and Tier-1 suppliers build upon these frameworks with their own manufacturer-specific EMC specifications. As a result, the automotive EMC landscape includes a wide variety of test levels, setups, and performance criteria.

Commonly referenced automotive EMC standards include:

• ISO 7637 – Transient conducted disturbances on vehicle power lines

• ISO 11452 – Radiated immunity and bulk current injection (BCI) testing

• CISPR 25 – Radiated and conducted emissions for onboard receivers

• Ford EMC-CS-2009.1 – OEM-specific EMC requirements

• GMW 3097 – General Motors EMC validation standard

To support compliance with these demanding requirements, we provide a comprehensive portfolio of automotive EMC test equipment, including high-voltage LISNs, EMC test antennas, BCI probes, hardened fiber-optic transponders, and hardened camera systems designed for use in high-EMI and high-voltage automotive test environments. These solutions enable reliable pre-compliance and full compliance EMC testing for conventional vehicles, EVs, and next-generation automotive platforms.
