  When i adjust minimum vertical division，it has a large ripple at 55KHz and large noice....
  I guess it may come from power supply.

• The AFG for DHO9x4S is a pluggin module.The LA port is directly connect to the main fpga.
  The other component looks all populated,
  so DHO800 uphack to DHO900 may need to solder up two drams and LA port only and flash the system?

• I really hope external power supplies don't become a thing. Who cares if your product is small if you still have to carry random stuff around.

• Is this power supply some kind of joke? But after replacing it with a decent one, it seems to be okay. Unfortunately, I can only see a thumbnail on the forum, and when I enlarge the image, it shows a different one.
  However, I wouldn't worry too much about it. It's cheap, so the first step would be to replace the power supply. Anyway it's a surprising move, it reminds me that cheap usb "thing" from FNIRSI

• It would be though gray marked for sure. Officially - it would be strange, but if some retailers can make a deal, it would be nice.

• If the power supply has a type-C connector, then its likely non-compliant as its constantly outputting 12V and will blow up your equipment? 
  Either way probably some junk thrown in by the seller or a temporary solution for a PSU. No way the real scope would ship with that. Still, indicates lack of filtering within the scope itself.

  Nope. Type-C can output many different voltages. You can negotiate with the supply and tell it how many volts you want.
