Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z<br />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.<br /><br />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!<br /><br />Mads from EcProjects found the 5us jitter problem:<br />https://www.youtube.com/watch?v=dHQ4MsMFJTk#t=172<br />https://www.youtube.com/user/EcProjects<br /><br />Forum: http://www.eevblog.com/forum/blog/eevblog-683-rigol-ds1000z-ds2000-oscilloscope-jitter-problems/<br /><br /><br />EEVblog Main Web Site: http://www.eevblog.com<br />The 2nd EEVblog Channel: http://www.youtube.com/EEVblog2<br /><br />Support the EEVblog through Patreon!<br />http://www.patreon.com/eevblog<br /><br />EEVblog Amazon Store (Dave gets a cut):<br />http://astore.amazon.com/eevblogstore-20<br />Donations:<br />http://www.eevblog.com/donations/<br />Projects:<br />http://www.eevblog.com/projects/<br />Electronics Info Wiki:<br />http://www.eevblog.com/wiki/
