Hello there,
I have a problem with my Rigol DS1054Z.
When I measure DC signal with CH2 I found problem with offset.
You can see it in print-screen and photos.
I tried to change probes, re-calibration in setup menu.. everything else.. and phenomenon still persist. :-\
Without any signal there is without any offset.
Do you have some solution for it?

You may get a clue from Part 4 of my thread here once I post it:

But you have to wait a bit for it.

Have you tried re-calibrating with the channel inputs shorted to ground? Also, don't forget to let the oscilloscope warm-up for 30-minutes before re-calibrating.

overdriven input..
