Hi,
I used the following VI (attached to the mail) in the past that acquires data from the specified channel, scales the data to engineering units, windows the signal, and performs the requested averaged frequency measurement. Power Spectrum, Power Spectral Density, and FFT are available frequency measurements. The resulting spectrum is displayed on a waveform graph.
You can find the VI on this link :

However, I have now 20 waveforms graphs of 'voltages v/s time' that are the results of a FOR loop (see attachment: Capture.PNG).
I wish to perform the FFT of these waveform graphs together using the same VI.
However, I don't really know what to remove from this existing VI and where I need to connect the output of my waveform graphs to perform the FFT.
Thank you for your help.
Regards,
