The image is from an engineering version of the product, not released yet.
Having spent a fair amount of time recently learning some FPGA programming I'm going to have a go at building a homebrew version of this DSO for my own learning purposes. The product they call DSO-203 which is a quad channel portable DSO.
You can find some of the information here http://www.seeedstudio.com/forum/viewforum.php?f=22 Hint: try chrome or google translate :-)
They have used an FPGA that is not readily available through my 'normal vendors' but it is available and it is a low power portable device and as the FPGA source is available it sort of makes sense.
The reason why I looked is I am in Cambridge and so are ARM and just over a mile away and I picked up a flyer recently about ARM chips and thought I would have a bash at something bit more complex.
