Abstract: This report describes a recent measurement effort conducted by the Institute for Telecommunication Sciences at a chamber located at the NASA Space Power Facility (SPF) in Sandusky, Ohio. The report describes the chamber and the measurement system, and provides some selected time– and frequency-domain results. A detailed description of the measurement procedures and post-processing is provided. The results obtained indicate that the SPF chamber exhibits robust reverberant behavior. The flexibility and efficiency of time–domain measurements is also demonstrated.

Keywords: antenna; impulse; biconical; chamber; decay time; direct pulse; discone; electromagnetic; finite-difference time-domain; fast Fourier transform; joint time-frequency analysis; log-periodic; oscilloscope; reverberation; ultra wideband
