Abstract:

A difficulty found in some electromagnetic compatibility EMC measurements is illustrated by showing that a particular measurement yields significantly different results when performed in a certain shielded enclosure compared with those yielded when performed in the open air. It is also shown that when performed in a large aircraft hangar the results are tolerably the same as those yielded in the open air. On these facts it is suggested that a worthwhile use for an aircraft hangar no longer devoted to its original use would be to assign it wholly or in part as a location for EMC measurement work. Further, a large shielded enclosure is likely to provide results more in agreement with open air measurements than would a small enclosure similarly used. Author
