Arrived at this point,i wish to ask the people of EEVBlog if this scope did really worth the effort to be made in home conditions.
I haven't too much cash in my own pocket for an "high end-mid range scope" but this project looks to be very delicious and so on.....
However tell me please what do you think about,thanks to all.

I wonder if, by changing the firmware and adding some RF front end circuits, it could double as a SDR platform?

I'm just an beginner,however your statements sounds like sarcasm?
Do you mean that this dso is bullshit?right?
lol sorry for my ignorance :(

No, IMO this statement doesn't mean your DSO is bullshit. Indeed, it looks quite nice, way better than many other USB scopes.

To double as an SDR platform means, NiHaoMike thinks this hardware is powerful enough to sustain high data transfer rates, is able to do pre- and postprocessing (like up- and down- mixing) within the FPGA, or maybe the complete signal processing for SDR can be done within the FPGA. So basically by adding some RF inputs and pre-amps, your DSO could be also used as a powerful platform for SDR development.

SDR requires high BW and very high dynamic range. If someone says your scope is an SDR (or SNA/VNA), that's probably the highest compliment.

So basically,someone of you would be ready to reapeat it by posting the final result on this thread ?
It would be very,very nice  ::)
