Window Functions at the Spectrum mode

Post by ultrasonic » Wed Dec 07, 2016 4:09 pm

Hello,

can somebody provide me please with additional Infos about the FFT Window Functions? I know that there is a short description of these Functions at the docu, but to decide which Function to choose I need more Infos. I am a new user.
I try to distinguish different machines (gearboxes) just by the FFT as our gearboxes sometimes sound bad.

Kind regards

The choice of Window Function to apply to an FFT, will depend upon the application. The user guide gives a brief description of applications and looking at this I would suggest Blackman, or Hann, may be appropriate for you.
