Simulink - Finding the FFT values.

I have obtained the abs(FFT) plot (showing peaks at 1kHz, 2kHz and 3 kHz) of an output signal using FFT spectrum scope(hann window type) in Simulink. Now how can i get the precise values of the magnitudes of FFT at 1kHz,2kHz and 3kHz?
Should I have to take the signal to workspace and then find FFT and thereby P=abs(FFT) and then find precise values of P from P(1k), P(2k) and P(3k)?
