It depends on the display mode, dot or vector.
First let you see only the single dots, last "connects" the dots together to a line.
The rigol got only vector mode.

Rigol releases new firmware v00.02.07 for DHO1000 and DHO4000 ~ 2023.05.17

[Model Supported] All the DHO1000 and DHO4000 series oscilloscopes
[Latest Revision Date] 2023/04/29


[Updated Contents]

00.02.07  2023/04/29

     - Custom external attenuation ratio
     - Add the merge display function of MATH window and simulation window
     - Add the window shrink function through Pass-Fail
     - Cursor module zero stagnation function, to solve the problem that the cursor is difficult to capture 0V first
     - Add a toggle switch for merging screens, which can display cursors in each split screen and synchronize the cursors
     - The measurement function adds [cursor area] measurement function requirements
     - Fixed crash issue in German mode
     - Pause to keep the afterglow display after turning on the waveform hold
     - Fixed the truncation problem of enlarged waveform after stoping
     - Fixed the problem that the adjustment trigger point could not be adjusted back to the middle of the screen after moving to the right for more than -50S under a large time base
     - Fixed Crash problem when restarting with probe


00.02.04  2022/12/14

something new came out  :)

Due to the name changing batronix sells it´s HDO stock for 10% less:

too bad they don't have the HDO1000... 8)

Hello,

I was wondering which device (Rigol HDO4000 or Siglent SDS2000X HD) is better in terms of noise. In the video "EEVblog 1501 - Rigol HDO4000 Low Noise 12bit Oscilloscope Unboxing & First Impression" Dave shows different measurements regarding noise.

He uses different memory sizes. With 1 MSample, the noise is significantly smaller than with 250 MSamples. This is because the HDO4000 then averages samples and therefore looks better.

I then used samples that Dave and Martin72 kindly provided and modified a program from Peter (PeDre) to determine histogram and RMS and peak peak.
Since I am not familiar with Matlab, my changes are certainly quite bumbling.

All in all, I think that the Siglent has the edge in terms of noise.

Best Regards
egonotto

Addendum: Rigol's data is true 16 bit. The data of Siglent is 12 bit. The 4 least significant bits are there 0.  This means that the data from the Rigol has already been processed. One problem with the comparison is the dynamic range, which is unknown to me.
