If the current DSO manufacturers are not taking up and adopting the Xilinq-7000 series in their scopes,
there is another solution!
Here is another option that I see:
Use everything from an existing oscilloscope, including the analog front-end, the controls and knobs, the display, the power supply, but bypass the main processor and insert a Xilinx Zynq-7000 instead. This could in fact be the Zybo board from Digilent.
Would it be easy to redirect the output of the analog front-end? Or would it be possible to tri-state the main FPGA and take over control through a Xilinx Zynq-7000? Would there be space inside to add an extra Zybo board without replacing an existing board?
Using this modification, you could retro-fit an existing oscilloscope and convert it into a powerful oscilloscope with super powers that beats the GW-Instek GDS-2000E
Hereby some examples of new model numbers that I propose, where Z stands for Zynq-7000 option, or R stands for Retro-fit option =)
Rigol DS1052E-Z
Rigol DS1054Z-Z
Siglent SDS1052DL-Z
Siglent SDS1102X-Z
Owon SDS7102-Z
Rigol DS1052E-R
Rigol DS1054Z-R
Siglent SDS1052DL-R
Siglent SDS1102X-R
Owon SDS7102-R
It should be possible, to open up the scope just once for the retro-fit, mount the Zybo board, a JTAG cable and other debugging cables into the scope, and after close it again.
The external design of the scope stays fully intact, while at the same time you would have full access to the scope, to control and monitor it from the JTAG interface and the other debugging cables.
Special labels or decals could be made, with a nice big "Zynq-7000" or the wording "Retro-fit", to proudly show the transformation
Maybe a small batch of these scopes can be produced, for an FPGA and DSP class room
