I working on a Simulink Signal Spectrum Analyzing on my own, and I'm stuck

Hi, I am working on my own to understand Simulink Spectrum Analyzing Fundamentals.

My curiosity is about the multiplication of the Rectangular and Sine wave in Simulink.

Note: I've added my .slx simulink file too.

So, I was trying to measure:

1-bandwidth,

2-repetition frequency,

3-pulse width,

4-sample rate

of my scope and spectrum analyzer.

Also do the values match with the signal in time and frequency domain?

My Configuration:
