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!
Mads from EcProjects found the 5us jitter problem:

Done.
Curious. Now in 2020 did Rigol fix that bug yet?
There is a 2014 firmware patch that vaguely needs Mentions a trigger bug but not what the bug is.
v00.04.00.00.00 2014/03/18
– Fixed bugs in triggering function
v00.04.02.04.07 2014/12/31
– Fixed triggering function
– Fixed storage function
– Fixed bugs of jitter in the signal under
the AC or low-frequency coupling
Its Jan 2020… did these problems ever get fixed?
is problem fixed
You can never have too many toys.
Didn't the firmware updates fix these problems?
Soo.. what have been the answer from Rigol about this?
A new update that will render the hackabilkity to zero?
I Just Got a Rigol 1054Z I appears that Rigol Fixed the jitter problem
I know this is couple years old, However, was the jitter issue ever fixed at a factory lvl with the 2000 model with AC coupling.
Bummer. I just bought a Rigol 1054Z to replace my old broken Tektronix 2430.
My DS1054Z works perfectly. AC and DC triggering with no difference. Software 00.04.03. SP2 and Board 0.1.1.
my oscilloscpe can't read transient activity from RC, RL, RLC circuit. Can you help me solve it? is there something wrong with my oscilloscope or I just need to make a few changes in setting
Thanks 🙂
Lol. Its a Jitter-Bug
My DS1054Z works perfectly fine from 100Hz to 300KHz. AC and DC triggering woth no difference. Software 00.04.03. Board 0.1.1.
did the 00.04.03 firmware fix the issues?
sir you must get to the point stop all the talking it make all of vid boring
"Gonesky!" I love it.
As i can see in your blog, Rigol has fixed the problem by issuing a new firmware. Dou you confirm that? Is These models steel a good option?Thks
I'm seeing the same problem on a scope I received today. S/W revision: 00.04.02.SP3
For DS1054Z, with official firmware 00.04.02.SP3,all works fine. No jitter.
the jitter on the sqare wave looks awesome, it's like a river
I have just put my Siglent SDS 1052DL through the same test and it is fine even when I have it AC coupled. No jitter, What is going on with Rigol?
Haha, the "couple of more scopes" part had me in tears of laughter. Good stuff.
WTF…
