SNR in frequency domain

Hello everybody, I need some help into the realization of a VI in which, starting from a periodic signal with some added noise, I could calculate SNR through measurements in frequency domain using the informations provided by a Spectrum Analyzer.
I have the two waveform (the signal and the noise) separately, and I added the two to get the noisy signal. I have calculated the spectrum for both signals, but now, I don't know why, but I can't proceed. I want to calculate the power spectrum but I'm a bit confused. I hope someone could clarify my ideas.
Thank you.

Does this help you in some way?
