Overcome UWB test challenges, Part 2

Posted: 14 Nov 2008     Print Version  Bookmark and Share

Keywords:UWB  signal generation  arbitrary waveform generators 

There are distinct advantages to Ultra wideband (UWB) technologies, but they are not without their test complexities. The various UWB signals and approaches create many challenging test and measurement issues that demand special test instrument capabilities. Generating and analysing ultra broadband test signals for UWB requires high performance arbitrary waveform generators (AWGs) and very broadband digital real-time oscilloscopes that can support the enormous bandwidth requirements of the UWB signal. In addition, UWB signal requirements present broadband amplitude and phase flatness challenges. Transient UWB pulses can be distorted by the spectral amplitude and phase flatness from both the test signal generator and measurement instruments. Pulse distortion affects, in turn, alter the spectral properties of UWB signals. This article by Chrisptopher Skach from Tetronix focuses on UWB test challenges, signal generation, interference testing and spectral mask measurements.
