;D No - you mean he "advertises" the DS2302A. He'll take your money for one, to be sure! But when will he deliver it? Since none of Rigol's BIG distributors (Tequipment in the US or Batronix here in the EU) - or even Rigol's OWN North American website - are offering them for sale yet, I somehow doubt your Swedish distributor has them in stock. I could be wrong - but if not, you're unlikely to find anyone who has bought one on this board.

I have written an email to the distributor to confirm availability =) Will keep you updated!

Batronix has already sold DS2000A models, even though they still only list DS2000 models at their website. I wonder when they will get it updated to say DS2000A.
There's also one in this topic who has already bought a DS2000A-S at a Norwegian distributor, even though this is not listed at Batronix website, let alone the DS2000A models.
So I wouldn't count on Batronix website for info on what available and not available from them, they seem very slow to update their website.
And the Rigol North America website is alo very slow to update info, they don't list andy DS2000A models yet either: http://www.rigolna.com/products/digital-oscilloscopes/ds2000/
So I wouldn't trust that website for what's available and what's not available either.
And from what I can tell Tequipment is already offering DS2302A even tough they just write "call us" for price. But their website say they have 3 in stock: http://www.tequipment.net/Rigol/DS2302A/

A dump will help.

Im waiting now for my JTAG dongle. Says it has shipped today.
Any other things to do meanwhile?
We´ll have to collect as much keys from mem dumps as we can. Thats the only chance to find out what scheme is behind the different keys. Uh and we have to give a hell of a lot BRAIN to it. (courageous hero cybernet pronounced many times)

But you ignored the rest of my point: as mentioned over and over again on these boards, the 2GSa/s rate does not necessarily support 300MHz well - unless Rigol has created a very good Gaussian filter - and there's no evidence that Rigol can do (or has done) this.
People just see "FREE" bandwidth and they think, "Shit, it's free so it has to be good!" But that's not the case - the extra BW can actually cause problems for the fidelity of your instrument. You have to believe that the representation of the waveform that the DSO is presenting is fairly accurate, otherwise what good is it? If the added BW is actually causing interpolation errors at smaller time bases, it's not a help - it's a hindrance.
