How use FFT function?

[Festter]

Hello,

I've got USB-6008 acquisition device. This device, for my program, is giving 100 of reports per second. I need to analyze the signal whit FFT function. The device is giving 1D array of scalars. I transform this array to dynamic data and now put it into the function but the function doesn’t give any signal. How can I analyze the signal whit the function?

Thank you

Search the Labview examples for FFT.  You will find several examples on how to use the FFT vi's.  I'm sure one of them will suit your needs.
