Total GRMS value

[blue_eng]

I was wondering if there is an easy method for calculating the total GRMS from a PSD. I have been using the spectral measurements express VI to calculate the PSD, and have found it less than straightforward to use the numerical integration block to solve for the total power.

You can consider using the new LabVIEW Analysis Express VIs to do some of the programming. LabVIEW 7 introduced the concept of Express VIs, and the Spectral Measurements Express VI in particular would help you out in this situation.
