Measurements using a Spectrum Analyser


I want to use a spectrum analyser as a Receiver to a transmitting DW1000 node in an experiment. I am looking at extracting the PSD. I think it is better to perform this experiment when the DW1000 node is in a continuous frame mode. Anyone have an idea of how to do this or is it possible to perform this experiment without having to configure to continuous frame mode by using the DIP switch configuration?
