Hello,
I am capturing GSM signals over USRP via MATLAB simulink and I got the necessary toolboxes and auxiliary packages for this. I don't have a problem with signal capture. But there's something I can't do. If my signal strength is over 70 dBm, I want my simulation to stop. And I want the image I get at that moment to remain on the spectrum analyzer. And I want to copy the data of the current image to the workspace. But I don't know how to do this.
Thank you.

Hi Nazli,
You can use the "Stop Simulation" block in combination with "Relational Operator" block to stop the simulation when signal strength is over 70 dBm.
Refer to the following MathWorks documentation for more information on:
To capture the content of the Spectrum Analyzer visually (as an image) requires the below two steps:
  1. Use the "To Workspace" block to export the signal data continuously to the MATLAB workspace.
  2. After the simulation stops, use MATLAB's plotting functions (e.g., plot, spectrogram) to recreate the spectrum analyzer's visualization.
Refer to the below MathWorks documentation for more information on "To Workspace" block:
