I picked up my Rigol DHO804 from UPS a few hours ago. This is from the Aliexpress seller.
I had to play for about 1h so this is the first impression with me mostly testing the 12bit ADC resolution.
Did not even connected anything to the input it still has the plastic caps.
Bad part is the nasty plastic smell hopefully that will go away but is very strong.
Here is what I got in the box (seems it has the Lenovo power supply). And the plug looks like Australian version with a US/Canada adapter.
The hardware and software version
Settings I done to save the waveform in .csv format and from memory not screen.
First I set the channel 1 to 50mV/div and 20ms/div stop the acquisition and then zoomed on screen 100x to 0.5mV/div
As it can be seen 12bit data was captured thus still some points at 100x zoom as many as expected
Then I reduced the vertical resolution to 500uV and reacquired the signal to see if is a true 500uV at 12bit and yes it is as you can see from the csv if you want to download the step is about 1.1uV as expected with 4mV per screen (8div * 500uV) and 4mV / 4096 = 1uV step.

https://electrodacus.com/RIGOL/RigolDS2.csvI have a DS1054z if anyone wants any sort of comparison. But there is no discussion that DHO804 is superior on any aspect. The user interface is super responsive no comparison with DS1054z. I think the fan is not as noisy as some made it look and not sure but I think DS1054z is noisier by quite some margin.
Form factor is excellent also. Touchscreen is useful and responsive but buttons are also good.
