And I'd like to do a power spectral graph(voltage amplitude over frequency). Is there anyway I can extract that information without running the experiment again? for example use FFT first then...? or must I use a spectrum analyzer? thank you for clarifying. ck [/quote]   Check here to include your profile signature.
