Hi,

You need to pass your aquired waveform through LabVIEW's 'Extract Single Tone Information' VI, which finds the frequency of the componant of your signal with the highest amplitude.

It's in Signal Processing> Waveform Measurements

Or, if your signal is more complex (it doens't look like it from your attachment) you'll need to do proper freqeuncy analysis with the LabVIEW octave analysis objects or FFT objects.

Christian.
