Mastering high end Xilinx/AMD chips clones is not so easy for China, imho.
The chip there could easily be a clone of an older type, like 15y old tech (virtex-6 40nm, or virtex-7 28nm).
Or simply a home made ASIC..

It should be easier to copy this part of the DT instead of making new entries. But I don't have MHO to test it - unless somebody will wan't to help with that (with testing).
Once mine arrives (late this month) and I'm sure it's working right then I might be able to have a go at messing with the DT. Need to make sure I can reflash the stock SD card image if there's any hardware faults that require return to Rigol though - I'll have a look at Dave's teardown to see how hard it is to open up without leaving evidence.

Apart from the warranty sticker, trivial to open, 4 screws back lifts off, access to everything.

Actually they have a cooperation with China about development chips for their market and they hold shares in those enterprises so they might not need to even steal anything but they most probably can use older tech on agreements basis which would explain using 3 years old chips.

For some reason Im very interested with a image of this SD card :)
LOL I thought someone posted a pic of the SD card, that you're so interested in.

I'm interested in these 500-1,000Mhz scopes, I haven't checked the prices yet, but it's good to know 1GHz scopes can be had by mere mortals with little money I guess, compared to the big names.

If it does the business just for that part, I wouldn't mind not having all the other options.
