You're very welcome to come here and share your conclusions.

I'm wondering does DHO900 really has a higher sensitivity.

From MSO5000 datasheet:
Vertical Sensitivity Range[3] 500 μV/div~10 V/div
[3]: 1 mV/div and 2 mV/div is a magnification of 4 mV/div setting.

From DHO900 datasheet:
Vertical Sensitivity Range[4] 200 μV/div to 10 V/div
[4]: 200 μV/div and 500 μV/div is a magnification of 1 mV/div setting.

Yes. One is 4mV/div and one is 1mV/div.  :-//

(And one of those two is using a 12-bit ADC to measure the signal, the other one isn't)

I saw in comments higher that MSO5000 can show 12-bit in High Res mode, I know that's just an oversample, but I can't find the same High Res option for the DHO series... does it even exist?

There's also a thread somewhere that tested that claim and found it to be more like 9 bits in reality.

The DHO is real 12-bit, so... who needs a hires mode? :-//
