Verification of the spectrum allocation and in depth analysis of the transmitted signals is very important in many domains. For example, the IEEE 802.11ad standard makes use of approximately 2 GHz bandwidth in the 60 GHz frequency domain. Researchers and developers of Automotive radar discuss the 79 GHz frequency band with an available bandwidth of up to 4 GHz. Finally the upcoming 5G technology for cellular networks discusses the use of up to 2GHz signals in the cm and mm-wave frequency bands.This technical evolution already indicates the need of signal measurement and analysis in the mm-wave domain with high bandwidth.Therefore, this application note presents a method to measure and analyze signals with an instantaneous bandwidth of up to 2 GHz using new tools on the R&S®FSW Signal and Spectrum Analyzer platform in collaboration with an R&S®RTO Digital Oscilloscope.
