Generation of wideband digital modulated signals in V-band and above is a challenging task and typically requires a set of multiple instruments. This application note aims at simplifying the task and looks into the analysis part as well. Latest signal and spectrum analyzers like the R&S®FSW67 are first to allow use in Vband up to 67 GHz without external frequency conversion. Up to 2 GHz of modulation bandwidth can be covered using the option R&S®FSW-B2000. Former application note 1MA217 describes V-band signal generation and analysis up to 500 MHz modulation bandwidth. This application note expands modulation bandwidth to 2 GHz but also an alternative setup is used to cover the necessary bandwidth and to obtain enhanced purity in signal generation.
