Theoretical procedure to convert anechoic radiated emissionmeasurements to OATS equivalent results for arbitrary radiators

摘要

In the last years, there has been certain interest in unifyinginstallations for radiated immunity tests (which require a completelyanechoic environment) and radiated emission tests (OATS). Thepossibility of making radiated emission tests in completely anechoicchambers has been suggested. Such a possibility poses the problem ofobtaining equivalent results with the new system to those obtained withthe standardized one. This paper presents a general approach to thatproblem, including the possibility of extrapolating results fromanechoic measurements at 3 meters to OATS measurements at 10meters
