You will find the VI "NI_MAPro.lvlib:Averaged DC-RMS.vi" by right clicking in the block diagramm "Signalverlauf -> Analoger Signalverlauf -> Signalverlaufsmessungen -> Mittelwert und RMS".
But I think my statement above is wrong. Inside the "NI_MAPro.lvlib:Averaged DC-RMS.vi" for RMS values the VI "RMS.vi" is used. The helpfile tells, the following formula:
Because it uses sampled data it calculates an approximation of RMS which should work for periodic and non periodic signals. Am I rigth?
