ABSTRACT
Cables are a major source of radiated emissions and receptors in electromagnetic (EM) coupling. Commercial equipment that is designed for electromagnetic compatibility (EMC) and that includes a well-thought-out grounding scheme and wiring and PCB layout can meet commercial EMC requirements with a number of unshielded cables connected to the equipment. When the equipment enclosure is also unshielded, the sources of emission are likely to be both the enclosure and the cables, although in some cases emissions from cables are higher when the enclosure is shielded.
