A piece of beautiful sh*t.
Small memory, deep in thickness, non touch, high price, outdated design and gold plated connectors (yes, they suck if you plug them often).
2M is fine only with segmented memory. With continuous memory, 2M=1ms at 2Gsps. Besides, at 2Gsps throughput, the capability of Cyclone 4 can easily dump it into larger DRAM, instead of SRAM.
It is really thick in size, compared to ultra thin designs which are becoming popular, like the owon ones (I own an original 2010 SDS7102, and I really appreciate its size).
The design uses expensive and outdated NS ADC, while new designs use Hittite converters that consume a fraction of power and cost a fraction of the cost, plus come with native 12bit mode.
The fact is, no one cares about performance of the ADC, since in such high bandwidth applications, most noise comes from front end, not ADC.
The application system is old too. A new design using Zynq can be cheaper while providing more on die SRAM and 10x CPU-FPGA bandwidth with DDR3 hard IP, and the effort is acceptable -- all HDL can be reused.
Compared to mid range Rigol scopes at the same price, I do not know how can it compete, besides better building quality. In addition, Rigol scopes can be hacked.
Finally, I really hate the gold plated connectors. When mated and unmated often, the gold layer will wear out, revealing half gold half nickel finishing. I'd rather get a scope with high quality thick nickel plating instead of soft gold plating.
For 1/3 of the price, DS2072 can be hacked to have 300MHz BW, 140M (?, not sure) memory and AWG.
For the same price, MSO4000 series offers tons of new features and much better hardware specs.
At 2x the price, MSOX2022A offers 100x capture rate with segmented memory and a bunch of other options that could be free if you are lucky.
