EEVblog #683 - Rigol DS1000Z DS2000 Oscilloscope Jitter Problems

Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z Some sort of modulated sampling/trigger jitter problem at 5 microsecond intervals (the "5us jitter problem"). And severe jitter with the AC coupled trigger mode, a problem which is also present on the DS2000 series scopes as well. NOTE: So many people have been confusing AC trigger coupling with AC input coupling people will be more familiar with. This issue has *nothing* to do with AC input coupling, it is AC trigger coupling!
