I'm using Simulink and i need to watch the magnitude and phase of the FFT of the output signal of my model. I use the Spectrum Analyzer but what i need is the FFT magnitude in a figure (i use Spectrum Scope) and phase of the signal in another figure. How can i do it? Thanks in advance. Néstor

I know your comment is very old. But someone else can use this link. I found a very good way to plot both magnitude and angle of an fft funcion. Please check it out:
