PSD Function isn't correct

[Garett]

I'm using the evaluation version of Labview 7.0 right now, and I don't think that the PSD function is correct.  It looks exactly the same as the FFT function.  I am evaluating random vibration profiles and I'm trying to get a PSD curve out of this.  I wanted to use Labview, but if it doesn't work in the eval version, then I have no hope for the version I'm going to pay for.

Garett,

All of our Analysis functions are pretty thoroughly tested and it would be quite an oversight if the PSD function was flat-out wrong. Perhaps you've found a particular singularity? Could you give a particular instance or circumstance of when the PSD function is returning erroneous results? An example VI would be even better!

Kind Regards,
