Frequency analysis of vibrations

[Lauvia]

Hey guys,

I have a "little" problem.

An emetted vibration is captured (with a laservibrometer) and the signal should be analysed so that

the emitting source can be recongnised (Quality contol)

How could I perform a frequency analysis of the signal in order to find out its caracteristics.

See the example of signal below

Thx

There are several FFT VI's.  Probably the best for your case would be a power spectrum.
