• 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.
