MOST EMI PROBLEMS ARE CABLE-RELATED!
Because most electrical cables are long compared to printed circuit board traces they are more efficient at radiating electromagnetic fields and picking up electromagnetic energy from the environment. As a result, most EMI problems occur because of the cables that are necessarily connected to the circuit. Even very small levels of radio frequency energy on the cable conductors can cause interference with other electronics. Similarly, radio frequency energy induced on the cables can cause circuitry to malfunction or have degraded performance.
EMI Analyst™ gives engineers a tool that both calculates energy emitted by circuits and interference to which circuits are subjected.
