How to see the GMSK/MSK signals in simulink scope?

I am following https://in.mathworks.com/help/comm/ug/cpm-modulation-examples.html#SoftDecisionGMSKDemodulatorExample-5, but this example does not connect the MSK/GMSK outputs to the scope. I tried to connect the output of the MSK block to scope but scope is unable to show any waveform. So how can I see the modulatedwaveform in scope.

I understand you are not getting any waveform while trying to display a MSK modulated signal in a Simulink scope block. Here are some steps to resolve this issue.

1. Check the scope settings: Make sure the scope is set up correctly to display the MSK waveform.
2. Double-click on the scope block to open the Scope Parameters dialog and ensure that the signal you want to display is selected and its settings (e.g., time range, sample rate) are appropriate. The value of sample time should be -1 (inherited).
3. Change the limits of the y-axis in the scope block in order to see the whole signal.
4. Reduce the stop time of the simulation to 10 or 20 seconds.
