Those offset calibration shots at 24 hours are not bad at all considering the input frontend is discrete. You can hardly complain about what looks like maybe half or three-quarters of a millivolt...

Does this zero them exactly?
You can push the Position knob to move the trace to the center graticule. It does not solve the problem because it is using the cal as a zero reference an it is off by a bit. Basically the cal is the issue.

As it seems it's not only the cal, it seems to get confused what cal values to use for a given channel when using or having used other channels.

- Be able to display a message from software on a PC. Ideally it would also have a Yes / No / Close button attached. I have a background in production testing and was often asked "Why can't I have a message on the scope screen to let me know?".
I've added these.
Seriously? I have no doubt this would be useful for pickle, and probably others as well. But you're talking about something that no other scope I am aware of has ever had. And you're thinking that asking Rigol for this will have some benefit?
Some pre-SCPI HP gear also supports similar functionality, so it could just be something HP like to throw in. Don't think I've seen a version with support for response buttons, though...
send ("D2HELLO WORLD\r\n");
send ("D2SOME QUESTION\r\n");
send ("D2ANSWR:PRES SRQ\r\n");
send ("D2IN 5 SECONDS\r\n");
pause (5);
if (had_srq ()) ...
send ("D1\r\n");
Channel 4 is the only one that looks close to normal on yours.
I don't have a major issue with this, I have other gear. That said will voltage measurements match between channels? My guess would be no not exactly. Could be out by a couple mV.
I'd say it more than meets its spec -- on my scope -- other units might not meet the spec, which is why I noted this in the BUGs section at the top of this thread.
I haven't noticed that but will keep an eye on it, I may have missed it. The position of the zero marker does change when a cal is done. Even if it comes out wrong, you'd expect it to be the same wrong every time. I've run the cal about 12 times on a well warmed up unit and the variations seem random.
I would qualify extremely slow CSV export of full memory as a bug. It takes around half an hour! It's not that complex operation to take so long. It should be up to a few times longer than storing to WFM file to account for additional processing, not more.
(...)extremely slow CSV export (...)It is slow to a stick, does work though.

IMO, there's no point muddying the waters with things that have basically 0 chance of ever being considered. I mean, there are 'wishes', and there are 'blue sky fantasies'. And I can tell you an 'ancient Chinese secret' that the longer your laundry list is, the greater the chance that the whole thing will get thrown away, and never looked at.
(...)extremely slow CSV export (...)It is slow to a stick, does work though.
It sure does, though it's not very useful if you can save two-three files (of 24MSa) per hour.

I've never tried that before, but just did, it's horribly slow. Something around 45 minutes to write a 350MB file. That's around 1/10 of USB 1.1 speed, let alone about USB 2.0. I've added this to the "bugs" section.
Most, if not all, HP/Agilent/Keysight DSOs seem to support displaying a message to the user via the :SYST:DSP command (it's listed in the programming manuals for the 54100A and DSOX2000 and also works on my old 1650B logic analyser); not sure how common this is with other manufacturers, as it isn't one of the commands required by SCPI as far as I can tell.
... Of course this can be done in software on a pc and force the operator to look at the pc.
Flatten trigger menu.
Remove "Setting" option and bring items under that sub-menu to the front. They are all important and frequently used. Lack of any indication of trigger coupling requires unnecessary key press to verify that setting. Bring coupling and holdoff to the front, noise reject can occupy second page.
Scope has nice system of long menus with indicators of currently visible page, use that. This will make it more consistent with channel options that have "two pages" and the rest of the menus.
I had asked Rigol about the Decode working on screen only and was informed the DS1000Z series has very little FPGA space left.
I would assume if that is true they are keeping their Limited resources for bug fixes not features and I would assume they are looking across the whole product line which includes the MS01000Z as well. So while implementing the decode may work on a base DS1000Z the MSO1000Z would run out of space so that makes the feature something that can not be implemented.
From a support POV if this is true it would be a nightmare. If they implemented the better decode on the DS1000Z but did not on the MSO1000Z I know I would be upset because I paid more for scope with LA capabilities so to have the support in the DS but not MSO would upset users so Rigol would be in a bad position. Best stance as a company is to fix bugs but not add features that can not be supported across the whole line of the supported boards.
Thats mine opinion FWIW based on a simple reply from Rigol, take it for what it's worth.
I do say that the decode function is not worth buying if this is the case.
