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. 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 FSW Signal and Spectrum Analyzer platform in collaboration with an RTO Digital Oscilloscope.
