A proposed peak power measurement system

Ultra-wideband (UWB) is an emerging radio communication technology [RD Wilson et al] that uses fast rise time pulses to convey information or provide radar-like images. Commercial UWB devices spread the signal over very large bandwidth, have mostly pulsed emission, and operate at very low power. Thus UWB represents new challenges in the way radio frequency measurements are made for conventional radio communication systems. This document describes a method which measures peak power exceeding the resolution bandwidth of conventional spectrum analyzers. First, it pointed out the matters on spectrum analyzer measurements, and then an instrument which combines a spectrum analyzer with an oscilloscope is proposed to measure on wider resolution than conventional method.
