Automotive EMC

Automotive electromagnetic compatibility (EMC) and full-vehicle antenna testing

The entire range of automotive EMC measurements from a single source

Today's vehicles integrate an increasing number of wireless technologies, radar and high-speed data buses. Thus, verifying that unintended electromagnetic interference (EMI) is within specified limits and that cars are immune to disturbances from external electromagnetic sources (EMS) is becoming an ever-growing challenge for the automotive industry. A new field is the infrastructure for e-mobility such as charging stations that need to comply with applicable EMC limits.

As a world market and technology leader with decades of experience in EMC testing, Rohde & Schwarz offers test and measurement equipment and customizable, turnkey test systems for performing EMI and EMS measurements on vehicles and components in line with all major automotive EMC standards, such as IEC, CISPR, ISO, UN/ECE and EC directives as well as with OEM and country-specific test specifications.

To ensure optimal antenna positioning and performance of complete vehicles, Rohde & Schwarz also offers full-vehicle antenna test systems. These systems are able to characterize the complete radiation pattern in 3D across all relevant frequencies. Additional test capabilities for wireless communications functionality, broadcast technologies, real-world modulated interferer signals and radar target simulation can be added to the system if required.

If you have any questions, please contact us.

Poster: Design with EMI in mind. Test early. Test often

Solving EMI problems early in the design cycle is more cost-effective than solving them later. This is an iterative process of employing best practices and checking. Of course, it is a trade-off – and needs to be balanced against functionality and scheduling. But solving problems and verifying early helps reduce costs. This poster helps you to design with EMI in mind.
