Just to be fair. Some years ago, here was Konnor user (AFAIR) who did develop entire framework for user's applications for DS1000z. That models are linux-free. Anyway the framework never gained traction here.

Yes Konnor did decompile the code, mapped modules etc.
But this is something he did by decompiling specific FW version.  In this case you can insert some of your code into memory and change pointers to point there...  He even created sort of framework code to insert code into it.
But this is kind of work that is similar to patching applications when you are circumventing licensing and hacking.
Not something that is easy or common. Also he decompiled entry points but all that doesn't explain what is scope doing and how is data being datapumped from FPGA etc etc...

This resulted with nobody ever used it. Because it is not easy and needs specialized knowledge..

Just arrived safe and sound via UPS, and at least it boots!  :-+

I've bought a £9 wall mount for it, although it is so slim that it doesn't take up much desk space anyway.

It didn't have any plastic smell when I opened the box, which some users have reported.

It came with the Lenovo 65W USB-C mains adaptor that takes a C5/Clover Leaf plug, a US mains cable and a UK-US plug adaptor.

It cost me £316 incl shipping from AliExpress so far, but I'm waiting for the customs invoice from UPS. Don't know what value the seller declared it as.
Update 26/Oct: never did get a customs invoice, so that makes it even more of a bargain  :)

Thanks everyone for the points on this mode - I had assumed that ultraacquire was Rigol's name for segmented memory.  Now I see it clearly spelled out in the manual (p. 200) that it has the record functions I'm looking for.

Now I just need to be patient until my local vendor gets stock.

Are you sure?

Make sure to check what can you DO with record mode. On other scopes that support segmented mode, you can do math, measure, decode etc. from segmented captures. It is not clear yet what can you do on DHO800/900 with recorded waveforms except looking at them.  For instance DS1000Z  had recording mode that did not allow you to do anything except looking at it screen by screen..

It seems that Rigol uses name UltraAcquire for some type of segmented mode. In that mode many of features are not available at capture time. When captured, it has Navigate segments window that allows you to look at captured stuff through some fancy display modes by (EDIT) time, frame number and there is some kind of search that nobody seems to talk about.
Actually read a manual again and in UltraAcquire mode only navigation available is Navigate by Frame Segment.  (EDIT)
On the other hand you have Waveform Recording mode that only allows you to playback captures (trigger events) one by one or animated.
There is no clarification that you can do search or decode or anything in this mode...

Everybody keeps being euphoric about all kinds of stuff but nobody seems to talk about if this scope actually can do any proper analysis with this two modes...

If I were you I would wait until someone gets one and proves it actually can do a job for you.  Maybe it does, but documentation is not helpful at all and nobody actually tested it yet..
