On measurements for EIRP compliance of UWB devices

Abstract

This paper discusses issues, methods, and limitations of using scalar near field measurements for determining radiator EIRP. Standard measurement methods and extrapolations used in compliance testing of UWB devices are reviewed. Next, measurements are performed which examine field attenuation rates in the near field of different radiating sources. Finally, these field attenuation rates are reviewed in relation to demonstrating DUT compliance.
