Experiences in Making On-Site EMC Measurements

This paper describes actual problems encountered, signal levels measured, and the solutions devised, in making on-site EMC measurements on a variety of large systems at a variety of sites. The unique problems encountered in making on-site emission measurements on large systems require devising quick practical solutions to a wide range of EMC problems using readily available equipment. A portable measurement kit, kept packed and ready for use in making these field measurements, is also described. The variety of problems encountered require the EMC engineer to be flexible and to adopt an open mind.
