The Rhode & Schwarz CRTU-RU is a Network Protocol Analyzer that was purchased to be used as a cheap Spectrum Analyzer. If you are using this for its Spectrum Analyzer functionality you will be better served to pretend that the model is CMU200 since there are manuals for that device and the Software and Hardware are essentially the same.
