SVT Spectrum Peak Search test

[chc5e]

Hello,
I'm trying to test out the functionality of the Spectrum Peak Search VI in the Sound and Vibration Toolset. Please see the attached testing VI which has a simulated spectrum.
For some reason, it can detect the presence of peaks but will not list their frequencies/amplitudes in the peaks array. Any ideas on what is going on?
Thanks for any thoughts, Hunter (LabView 6.1 user)

Try filling in the spectrum info cluster, specifically the Window, Window size, and FFT size. FFT and Window size are currently 0.

Hmmm.....thanks for highlighting these. Opening up the cluster to view these on the front panel and then rerunning the VI actually produced results...even leaving the values at there defaults.

I had to change the window to Hanning to get accurate results, though. Interestingly, it worked even with window size set to 0.

Anyway, thanks for the help.
