Simulink - How to scale the amplitude of an FFT magnitude block?

Hi all!

Is there a way to scale the amplitude components of the output of an FFT magnitude block in Simulink?

I have a simulink model where I would like to scale the amplitude components. I tried a 'divide' block to do the scaling. But using it will also alter the frequency scale (as can be seen in the vector scopes).

Anyone know of a way to scale the amplitude components only without altering the frequency scale?

I've included my simulink model here.

Thanks for any help in advance!
