UWB EMISSION MEASUREMENTS WITH SPECTRUM ANALYZERS

The verification of emissions according to EN or FCC standards is mandatory to avoid any interference with existing users. Besides the common emission tests with measurement bandwidth up to 1 MHz and mean power measurements, most regulations also require to test peak transmission power within a 50 MHz bandwidth to avoid interference with any existing wideband applications, for example radar receivers. This application note provides information how to perform spectral emission measurements on UWB signals with spectrum analyzers using wide bandwidth RBW filters, and explains the capabilities and the limiting factors of the Rohde & Schwarz FSW signal and spectrum analyzer to perform this measurement. The next sections will give further details.
