I’m trying to read AC ripple on a DC signal but the graph always show the combined signal DC+AC and not the AC ripple around zero value (so without the DC component). In the software I can choose between AC coupling or DC but choosing one or the other does not have any effect on the graph, it always give the combined value.
Actually, it did once gave the AC ripple around zero volts for both channels, but after switching back to DC I cannot get the AC ripple graph back anymore. It looks like a software issue, but as im new with scopes I can’t exclude the possibility of me doing something stupid
I’m using Win 10 64 bits. Downloaded the software from the Velleman site, version 1.02.
Anyone got ideas? Thanks for your time.
