Capability and Complexity Growing in Modern Vehicles
Modern vehicles rely on dozens of microprocessor based electronic modules to perform control, monitoring, and convenience functions. These modules are connected by un-shielded wiring harnesses that span the length of the vehicle to support high speed digital communications, carry vehicle power, and interface other signals. The challenge for manufacturers is to ensure they are immune to radio-frequency (RF) signals that permeate the vehicle environment.
To reduce risk, vehicle OEMs require module-level EMC testing to validate performance and immunity. Whole vehicle EMC testing becomes an important final verification step to confirm system level performance, assure vehicle safety, and provide regulatory compliance results for markets that specify testing.
Whole Vehicle EMC Testing Benefits
- Confirm component unintended RF emissions do not interfere with on-board or off-board receivers
- Verify no un-commanded movements, state-changes, or responses to applied RF immunity testing
- Comply with government regulatory EMC requirements
