get frequency and amplitude from fft module

[Bill El Sayed]

Hi,

I am trying to save the frequencies and the corresponding amplitudes of a certain signal in an array.

But I couldn't find a way to get the components of the output of the FFT Spectrum(Mag-Phase).VI

Please could you help me get the output components of the mentioned FFT VI

Thank you,

Bill

It's a cluster so you would use the unbundle by name to get the f0, df, and magnitude array. If you really need a frequency array, use a for loop with a shift register. Initialize the shift register to the f0 value, increment the shift register value by df, and run the for loop to a count equal to the magnitude array.

p.s. This has nothing to do with instrument control. If you have a NEW question, you should post to the LabVIEW board.
