To extract data from the Spectrum Analyzer in Simulink to MATLAB you can use a "To Workspace" block in simulink and to capture the signal data and log it into MATLAB workspace.
You can connect the signal that is provided as input to the Spectrum Analyzer block to the "To Workspace" block and then run the simulation.
After the simulation, the data will be stored in MATLAB workspace under the variable name specified in the "To Workspace" block.
To learn more about "To Workspace" block, kindly go through the following documentation:
