Extended Resolution Bandwidths for Ultrawideband (UWB) Measurements

The R&S®ESW-B8 and R&S®ESW-B8E extended bandwidth options allow the R&S®ESW EMI test receiver to measure with a resolution bandwidth of up to 80 MHz. The increasing number of wideband applications (e.g. radar sensors) and accompanying standards means there is now a greater interest in wide bandwidth measurements.

This application note describes the following topics for the R&S®ESW EMI test receiver:

► Characteristics and implementation of RF signal paths

► Image responses and how their rejection is handled

► Ultrawideband measurement applications as required e.g. by ETSI standards

► Solutions for efficiently coping with bandwidth limitations in the range above 8 GHz
