-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.
Why would this be your conclusion? That equipment programmed to write it's own invented file format isn't doing it correctly? But that the third party software IS reading the file correctly?
As I mentioned already, the format described in wfm_view and other online sources for the DS1000 series is not valid anymore. The locations in the header of pertinent information (sample rate, sample size, etc) - and the manner in which the DSO stores sample data has been altered quite substantially. It's likely that with 2GSa/s the Rigol is storing the data in a different fashion than with 1GSa/s - since the 2GSa/s setting was not available in the DS1000 series. No one has published specs on the new format yet - or written any readers. My Rigol doesn't have any problems writing - and then later reading - a 2GSa/s WFM file - so clearly the fault is in the software. So, instead of claiming, as you did first, that the Rigol wasn't sampling at 2GSa/s - or secondly, that the Rigol isn't writing the 2GSa/s to the file (both of which are easy to prove otherwise) - you should be studying the new format and discovering the changes so that you can get Baudline to work correctly.
I haven't "claimed" anything here just stated my ongoing observations.
It "seems" to be sampling at 2GS/sec.
...suggesting the original data isnt 2GS/sec.
Which stands currently that the 2GS/s wfm file when loaded into baudline only seems to be at 1GS/Sec

Both of those 'observation' were implying that the Rigol was doing something wrong - when it was ridiculously easy to prove that it was doing those things correctly with simple experiments - and thus Baudline was at fault .QuoteWhich stands currently that the 2GS/s wfm file when loaded into baudline only seems to be at 1GS/Sec
Yes, because Baudline is obviously reading the file incorrectly.
Well not really, my understanding was incorrect. Baudline was reading the file correctly it was just in the wrong order / format.
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.
Does anyone know why these DS2072 scopes are completely unavailable from any US sellers? It seems they have been out for more than a year, and although I can find dozens and dozens of shops selling the DS1052, I can't find a single one who has any DS2072's.

Is there a problem with them? Is it being discontinued or replaced? Can't figure how they could be as scarce as hens teeth after more than a year on the market.
Many of the owners here bought it from Tequipment or other places in the US until very recently. So I would imagine there's just a backlog at the moment.
Tequipement had a 6 week wait but not any more. and often w/discount.
PM Tequipment on EEVBLOG, he is VP.

I just got off the phone with TEquipment and they have none and have a waiting list of people - their website says 4-6 weeks, as does Rigol's website.
There are also none for sale on any US site, or even on eBay. There are 2 on eBay, all being shipped from China suppliers, and being sold for 40% above MSRP.
I ordered mine from tequipment in early March, and at the time was told the 2072 was on a 2 month back order. I opted for the 2102 because I could.
Now that we know a SigGen option is in the works, I wonder if production hasn't been paused for awhile waiting for the new boards?
What is a "sig gen option"? I haven't heard about that... is there going to be a waveform generator option for a newer revision of these scopes?
From Tequipment catalog:
Model
DS2072(70MHz,2-Ch Scope)
DS2072-S(70MHz,2-Ch Scope + 2-Ch 25MHz Waveform generator)
DS2102(100MHz,2-Ch Scope)
DS2102-S(100MHz,2-Ch Scope + 2-Ch 25MHz Waveform generator)
DS2202(200MHz,2-Ch Scope)
DS2202-S(200MHz,2-Ch Scope + 2-Ch 25MHz Waveform generator)
It's not clear if it's going to be an option - or just another set of models (DS2000-S series). There is info in this thread.

Im happily reading 1400,14000,14K, and 14M Points via LAN and USB interfaces with firmware FW (01.00.00.03) not at the same time obviously. - Using Linux USBTMC and via the LAN.
Or does turning on the 2nd channel cause all hell to break loose? which was the point of the bug report...
Please report back findings here for compilation and delivery to Rigol.
My result
Love this scope.
Glad that i stopped a Owen order and go for this DS2.
http://www.silcon.cz/ is a Verry good place to buy from.
