EMC/EMI Testing on a Modest Budget

When considering the addition of radio frequency reception and transmission equipment to the suite of electronics already installed on a modern motor vehicle, numerous issues must be considered and tested to ensure reliable and safe operation not only of the additional equipment but the vehicle itself. This paper addresses some of the major issues and suggests modest design and testing practices that will accomplish the desired reliability and safety.

The modest design and testing proposed addresses good engineering practices of electrically bonding metallic surfaces of the vehicle, grounding equipment, shielding signal cables, introducing filters, and appropriately separating cables into bundles.
