So is it available then? :)
Or do I miss something here...

Siglent, like GW-Instek before them (and every other Chinese manufacturer), is late to produce a < $1000 DPO - since Rigol beat everyone to the punch and took over the market share. So they, like Instek before them, are rushing to do anything they can to try to reduce Rigol's share. In GW-Instek's case, it was hurrying out a product which just wasn't competitive enough - in Siglent's case, they are dashing out publicity statements, "for sale" internet ads, and demo models of a product which (although perhaps as nice/nicer than the DS2000) is not ready for market yet. You can read all about it in other threads here.

Is there a way to take apart the gel files, or are you decompiling from the jtag dumps?

I decompiled memory dump provided by tirulerbach (the one after entering 'AAAAAAABBBB...' license code) and after I understood how original decoder worked, I wrote my own version of it.

--- End quote ---
Yes, Rigol uses blackfin in DS2K scopes.

what about the gel files?, what format is that?, not this I guess: http://processors.wiki.ti.com/index.php/GEL
