METHODOLOGY FOR ELECTROMAGNETIC-INTERFERENCE MEASUREMENTS

Although electromagnetic analysis tools can provide good numerical dat a about the effects of electromagnetic interference, measurements are the method of choice for obtaining quantitative, accurate data on elec tromagnetic noise problems. Furthermore, since electromagnetic interfe rence measurements often provide the only data accepted by most regula tory agencies, the measurements and their accuracies have recently bec ome a very important issue in order to regulate and harmonize various electromagnetic compatibility emission and immunity standards. The mea surement techniques and instrumentations of most use for making accura te electromagnetic interference measurements are presented in this pap er.
