Advances in GTEM to OATS correlation models

The addition of an OATS (open area test site) radiated emissions correlation algorithm to a GTEM (GHz transverse electromagnetic) cell allows performance of radiated emissions testing, equivalent to that conducted at an OATS in the GTEM. The original correlation model and the computational algorithm based on this model accurately addressed the measurement of radiated emissions to commercial standards, over the frequency range of 30 MHz to 1 GHz. In the present work, the authors examine new additions and expansions to the original model and algorithm. New additions include measurements to telecommunications specifications, measurements from 9 kHz to 30 MHz for electric and magnetic field measurements, and measurements to MIL-STD requirements and measurements above 1 GHz
