      Hi Feras,

      In order to be able to set the spectrum analyzer to show the plot in the frequency you have chosen, you are going to need to increase the samples per bit parameter to be able to see it properly (according to Nyquist theory). I increased your samples per bit from 8 to 128 and now I have the right plot.

      Regards
