Content
This paper discusses important considerations for performing meaningful electromagnetic radiated susceptibility tests of automotive electronic components. It is written primarily to aid new EMC engineers who are, or will be, involved in evaluating the susceptibility of electronic components and systems. The objectives are to minimize some of the pitfalls so common in performing measurements and to introduce new improved techniques that have been developed or have been proposed. Factors discussed include: 1) a review of some present susceptibility measurement technique problems; 2) swept versus discrete frequency testing; 3) test-field exposure time; 4) diagnostic testing; 5) implications of conducted versus radiated susceptibility testing; 6) relating testing results to operational “real world” environment; and 7) the need for complete vehicle testing. Recommended testing procedures are then proposed.
