So it´s a channel with no input signal ?
So it´s a channel with no input signal ?Vestom shows the channel coupled to GND where Performa01 back on P3 in the following post uses AC coupling and BW limited 50 Ohm.

Who's right IDK but AC coupled to remove any offset and 50 Ohm with BW limiting seems more like a real world measurement.
I'm not sure what the value is in practical terms in identifying the discrete levels, other than for academic purposes? If it's preceded by a noisy front end, all bets are off.

Oh and BTW, Performa01 has a preference for Dot mode also.

I managed only about a 4dB improvement (not even one bit) in resolution by switching to 10 bit on the Siglent under the same criteria I used documented above in the screen shot.
What I'm convinced of is that the Rigol MSO5000's front end is quite a disappointment, and then some.
However, in all modes I have a -150uV offset. Outrageous! But it is also unusual warm weather right now...

That was the main reason why I´ve changed to siglent.
Did a ripple measure with the 5000 and it was terrible, after this my decision was clear to give the new siglent a chance.
And it didn´t disappoint me so far.
Plus the bigger and better screen, plus 50 ohm inputs.
and it would just take too long to ever save up for a $5k scope like the MSO5000 series.
So you basically say that the Rigol Phoenix chipset is a big failure?

I have quite a long list of pros and cons for both scopes, but thus far the MSO5000 has many more cons than the SDS2000X Plus.

Comparing the benefits/missing things of the sds2K+ in the sdk2k+ thread....Why needing a new thread for it ?
Yes, I run with the channel grounded (GND coupling), but that was just to measure the noise level, which BTW was about ~65uV std deviation (in 8 bit mode), slightly better than the specified 80uV (@500MHz BW). But mine being BW limited to 100MHz probably also helps a bit.

I only have experience of the MSO5000 with this chipset, so my evidence is very anecdotal.

There are some weird surprises for both. For example, you can’t do a serial bus search on the Siglent at all, but you can search for analogue things like edges and runt pulses, so you need to rely on your trigger. On the Rigol, you can do serial bus searches, but those searches are only accepted on analogue channels, not LA channels.
I’m tempted to do a full comparison, these are essentially direct competitors to my mind.

Nezbrun ?
SDS2kX Plus probe attenuation settings can be set to a User Default.
The Default Key setting menu is in the Save/Recall menu.
Best to do a factory Default first and a Secure Erase before setting a User Default.
Expansion/Trigger point can be fixed from within the Utilities menu.
