First picture on EEVblog of the new R&S MXO4 series oscilloscope :)

He uploaded the video two days ago.

Cool. The Rigol is (slightly) lower noise than the MXO4 though. No surprise given the MXO4 has a 1.5GHz front end. Even if you bandwidth limit, the inherent design noise is higher.

Agreed. Segmented mode on most scopes is rather fiddly and annoying in comparison.
bozidarms:
Noise values for one "Industry-leading system architecture: 18-bit vertical resolution/12-bit ADC" are not so exceptional low as R&S would like them to be.
For MXO4 is stated - RMS noise floor ( HD mode ??? active for bandwidth ≤ 500 MHz)
sensitivity:
HDO4: analog bandwidth 1 GHz LeCroy HDO 1 GHz
0.5 mV/ 98 µV
1 mV/ 104 µV 145 μVrms
2 mV/ 116 µV 145 μVrms
5 mV/ 152 µV 150 μVrms
10 mV/ 238 µV 155 μVrms
20 mV/ 436 µV 185 μVrms
50 mV/ 1.01 mV 275 μVrms
100 mV/ 2.47 mV 500 μVrms
200 mV/ 4.43 mV 1.75 mVrms
500 mV/ 10.13 mV 2.75 mVrms
1 V/div 19.96 mV 4.90 mVrms
For example, every LeCroy HD Oscilloscope has in sensitivity over 2mV significantly better values, partly 4x better!
That is not bashing, only pure facts.
BUT, real bashing can one find on R&S official pages:

If you read something like that, you will be speechless - it's amazing that a company with such a reputation uses such lousy and dirty tricks. - just sad.

Every manufacturer does those comparisons. Lie by omission is the marketing modus operandi.

Except when the manual is wrong. You have to go into the Segmented menu to find the option to change it.

They must have moved it around.
Still, the clue is there...
