Hmmm, I have no idea. I have pretty much the same values every time I check them.

Unless there is a physical defect in your scope or connections, I suspect your issue is environmental. Is your scope well grounded?

Hey guys,

I just got my DHO1074, updated the firmware and unlocked all options.

I noticed that sometimes there are white triangles at the top of the waveform view.... anyone knows what that's about?

Hello,

it is a DHO1074 it is grounded
I can't say for sure whether there are environmental problems or problems with the ground. However, the values normally change if I change a setting on the scope that has nothing to do with the measured value. For example, switching on a different channel.
