(...)the programming matters (FPGA, CPLD, DSP), there are billions of way to win or screw up the DSO design.

Probably in CML board the IC footprint right of FPGA is populated.

And I'm with you at the programming thing.

to DSP, so potential hack by replacing the whole firmware could be much easier .. of course if you get somewhere
ATTEN firmware (CML or higher bw CAL models)

About firmwares I can't find them in web, maybe my fault...

One of the things I wanted to know, were the references of ADCs, but no luck, they removed it  >:(

Probably they are using slow rated ADCs...

Richard W.:
Nice pictures, but build quality doesn't impress me really.

What means the symbol on picture 14.jpg between the CE and the crossed recycle bin?

Chinese EFUP label. In this case 30 years of "Environment Friendly Use Period" before hazardous substances are likely to leak out of the equipment.

Mechatrommer:
nice scope. that dodgy fuse can take something at least 10~20A by the look.
