cadence transient spectrum

I can use calculator to do fft.But I also wonder how to use Fourier and Fourier2ch to do that.I tried to find answer in the online help of Cadence.But I couldn't find help about how to use these two cmponents.Could you tell me where I can find that? I used that in my circuit to do transient analysis.But i don't know how to converter that into frequency domain.

Thanks for help.
