How to correctly plot FFT

[purvangg]

I am using LabVIEW with IMI 682B03 Acceleration module.

I am taking the data Via. PLC into LabVIEW using RS485.

I am unable to get the FFT from the data.

Please Help Me With The Same

Hi Purvangg,

Your code kept becoming unresponsive on my PC. But I was just about able to open the Spectral Measurements express VI for long enough to see how you set it up (then it froze again!).

Assuming you are able to get data through from your FFT - I would recommend changing the settings to 'Power Spectrum' and 'Logarithmic' to see a more traditional FFT.
