ADRV9361 Increasing MATLAB Spectrum Analyzer Passband to View Multiple Data Transmissions

Currently, we have two ADI RF SOMs set up at different transmit frequencies (utilizing the zynqRadioQPSKTransmitRepeatAD9361AD9364ML) being hard-lined with a combiner to one of the SDR receivers (using example, zynqRadioQPSKRxAD9361AD9364SL).  We have verified both signals are being received at their respective frequencies but we are interested in seeing both passbands on a MATLAB spectrum analyzer.  Unfortunately, Simulink won’t allow us to increase the spectrum analyzer passband and we aren’t sure how to configure our setup to achieve our goal.

 

Ideally, we want to widen the receive passband to capture both transmitted signals and then frequency shift them to be de-modded independently so we can have multiple data streams from several sources; similar to the FM example from class.
