Cabling and Grounding
This one-day seminar covers EMC systems considerations as
well as the basic EMC subjects of cabling and grounding. Emphasis
is on applying the systems approach to EMC early in the design. Cable
types, cable coupling mechanisms, and the importance of cable shield terminations
are covered. The purpose of grounding is discussed and a new EMC
grounding philosophy is presented.
