REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Jason:
I bought one from rigolna.com a couple weeks ago when I saw they were back in stock; it shipped out the next day. I suspect "4 to 6 weeks" is their general lead time and it's not really tracking their incoming shipments.
Yeah, I also considered the DS2102 to avoid the wait but the price jump was a bit too much. The DS2072 was already more than I wanted to spend (this is just for hobby use).

Very interesting! Thanks for the info and link in the previous post. That actually seals the deal for me. One of the reasons I didn't want to splurge on the DS2102 was because I had planned to get the Rigol function generator as well... don't really need it, just like it :D and it would replace my aging fluke and give me a few more features I don't use too much. But if the -S model will have function generation capability built in, I will stick with my old Owon for the time being.

I am afraid that it will not be a option that can be added to an older DS2000 series scope.

Nobody knows anything for sure. And there are already plans made by some people to look into a retrofit if it's not something offered by Rigol.
marmad:
I worked again on testing the Rigol FW sample-memory reading bug - and I've finally figured out the exact parameters of the bug - which should help Rigol engineers track it down. This bug has persisted through all of the last 3 official firmware versions, so I'm really happy to finally nail it down. :)
A detailed bug report and a special version of the sample-read software has been sent to Drieg - which will be passed on to Rigol Monday for processing into the next official release. From what I know, the 'measurement bug' first spotted by EV in the latest FW (01.00.00.03) has been fixed - so if they can just get rid of these (plus Teneye's 500uV trigger offset and any lingering Cursor issues) we might be approaching the mythical 'zero bug' territory.
Anyway, for those of you with any interest, the precise specifications are as follows:
When both channels are on, any memory read that requires more than one packet of data will ALWAYS fail. The maximum packet size is around 2MB - so any memory depth >2MB for byte mode or >~200kB for ASCII mode can not be read correctly.
I was mistaken about this - more info here.
