Hi Attila, Many thanks for your quick answer, I was expecting something like a factor 1/2, but with the script it's much more clear Best

Hello, Using ADP3450 in network analyser mode, I made the mistake of using the "Relative to ref" option with "Vmrs" plotting option. Actually, I understand it does not make sense to ask for an amplitude ratio in true units since it's a ratio...and can only be plotted as a linear or dB gain scale. And that the ambiguity come from the need to plot on the same graph, the Channel 1 in true units, whereas the other ones are asked in relative amplitude. The attached file illustrate two measurements made with and without the "Relative to ref" option. My question is : what is plotted when both "Relative to ref" and "Vmrs" are selected ? Is there a simple way to recover the RMS value or the Gain from measurement that have been made and exported with way) Thanks for your help, Xavier testADPnetwork.pdf
