Before passing the waveform to Power Spectral Density VI, it was divided by 1000. I am getting my PSD output in dB.
How could I undo the effect of the division? Is there any factor to scale by?
The PSD used is the standard Labview VI, with all default values (except with dB on).

No I don't....I only have the scaled version now...

Someone else many come along that's a lot more familiar with the underlying math, but I'm pretty sure you're hosed.
The lesson that you need to learn here is: always, Always, ALWAYS save the raw data -- then after the analysis save the results in a different file. And backup everything.
