Signal input with the function : harmonic distortion

Hello everyone
I'm measuring some variables like acceleration, speed. among others and I want to analyze the harmonic waves. I am using the harmonic distortion function, but I came across a problem. The function as we can see in the image asks for an input signal and I want it to be the graphics that I am doing in real time, such as acceleration. The problem is that I have waveform chart output (in red) and I need to have an input to put in the harmonic distortion function (in blue).

I await answers, thank you very much.

Best Regards 

Ricardo Rebelo

Hi Ricardo,

 

that function expects a waveform, but you are creating just a cluster of 3 elements for those charts.

You need to create a waveform instead!

Hi Ricardo,

 

a waveform consists of t0, dt and an Y array. There is a whole functions palette dedicated to waveforms.

And there is the LabVIEW help explaining all those functions in that palette…

Best regards,
GerdW
