EMCPartⅦCabling

1.IntroductionAnyone working in a systems electromagnetic compat-ibility environment is usually painfully aware of the fact that,often, the weakest link in the system is the cabling. Whetherthis is the cable or the connectors themselves, or more likelythe interface between the cable and the connectors where theremay be a poor connection of the cable screen, the ability ofcabling to leak or absorb spurious signals is a cause of muchEMC frustration. This section will address the basis of thecabling related EMI phenomenon and the best cabling practice.
