BTW. They suggest me to visit their Munich office :)

Well, that's one reason the Rigol (and Hantek and Owon and Siglent) threads are so numerous (and often large) in this forum - because we (the owners/users of the equipment) are offering support to each other to make up for a deficiency from the manufacturers. If the Chinese companies provided better documentation and software for their devices - as well as a speedy, reasonable level of after-sales support, many of us would probably spend a lot less time here :)

I do agree, Mark. But if so, why not to make a separate topic for FW updates to put there FW files. Because now everybody here need each time to ask his dealer for help.

I noticed the wfm file for the DS2072 isnt the same as the DS1052E. It contains preamble. Either case Ill check with the baudline author.

I'm guessing it's almost certainly #2 - there wouldn't be any logical reason for #1 (except a bug). And yes, the WFM format has been drastically changed - and there is no published documentation about it - typical Rigol/Chinese behavior which pisses me off. And they appear to have changed it even some more in the latest firmware version (01.00.00.03)!
We are currently working on documenting the format - so that conversion routines can be written.
BTW, if you want to know what version of firmware you're running, you need to use a specific sequence of buttons. Read the instructions at the bottom of this post.

Hi,
I have 00.00.01.00.05 Software, Hardware is 1.0.1.0.0, rest I guess isnt important? - The proceedure you give for obtaining the information is part of the calibration routines - I ended up in channel gain menu |O
/not related to the wfm parsing,
The 01.00.05 firmware locksup with RAW reads even in stop mode, currently Im resorting to reading the display data and processing that. Not ideal - Thats already on the forum and theres a test app, not good for me since I dont use windows at all, I used rigolterm and the scope crashed with manual / basic command entry.
The dealer sent me the latest firmware 00.01.00.00.03 together with the DS2000 programming guide dated July 2012. Fine for usb control (if raw worked, need to double check the commands while in the same room as the scope.)
Im also aware the firmware update proceedure is a little more involved, will check that.

The dual channel example is from a TEK TDS1012B scope.
-Anyhow the .wfm file format is rather odd, baudline is able to parse unsigned bytes easily - it will display the spectrum showing e.g radio channels in the right places but only for sample rates set to 1GS/Sec, the file was captured at 2GS/sec, if I load that setting the sample rate accordingly they are in the wrong "spot" suggesting the original data isnt 2GS/sec.
I will make a file with e.g 100 MHz marker (via sig gen) & capture it to investigate the file further.
Regarding other comments: We gain in hardware what we loose in documentation...
Batronix have been fast and friendly but ultimately must also resort to emailing Rigol...

The 2072 is less because its the entry price. Its made to grab attention. The insides should be the same.

Since the DS1052E/DS1102E fiasco started on this site, Rigol has spent some time beefing up their security when it comes to unlocking features of their hardware. True, stopping the clock in their DS2000/DS4000 and possibly some other embedded devices of theirs can prevent some trial options from expiring, but the codes for unlocking said features are encrypted quite strongly and I don't imagine buying a DS2072 hoping a hack will eventually appear is a very safe decision. Always make sure the decice you are buying, AS YOU ARE BUYING IT, is capable of doing what you need. If additional features become available over time, then that is a perk.
