Application Note

Extended Resolution Bandwidths For Ultrawideband (UWB) Measurements


Ultrawideband (UWB) technology has a growing number of applications in communication technology, radar sensors, or IoT equipment, among many others, all using an extremely high bandwidth of 500 MHz or more. The ETSI standard requires in-band testing for product certification with a resolution bandwidth of 50 MHz for these UWB products. This application note explains technical reasons for the bandwidth limitation and presents solutions for regulative UWB testing using the R&S®ESW. Download the full paper for more information.
