Possibly Bode? todo a Bode plot? Bode plots give the frequency and phase response of a system. If you simply want to measure the frequency of a signal there is a vi that will do that "Harmonic Distortion Analyzer 1 Chan.vi"
Thanks for the advice. It is the correct spelling. It is based on the Bose-Einstein theory. (whatever that is)! I think i remember seeing this name under one of the frequency measurements. It was stating that the vi based its calculations on this theory.
