Time-domain measurements of radiated and conducted ultrawideband emissions

This paper summarizes results obtained from time-domain full-bandwidth emissions measurements of selected ultrawideband (UWB) transmitting devices. Brief descriptions of two NIST-developed measurement systems are provided. High-fidelity time-domain waveforms are shown, along with associated amplitude spectra for several devices. Results are shown for both conducted and radiated emissions from UWB devices.
