SDS3000X HD max speed is stated as up to 28000/s and it is true least at current FW 1.0.3.3.

I also wonder where from come suspect or claim that it is not true.
Later when/if I have idle free time to take SDS2kXHD on board (if need) I can also check it.

With this test I measured ~28300 fail pulses/s from Aux BNC when test was continuously running as in image below.

My bad (even though it was posed as a question). 😉

Still though, it's crazy to me that a hardware based feature would have the best performance in the worst model. Hopefully it's a temporary firmware limitation, but even that is odd since at least the 2KXHD model has had plenty of time to mature.

According to the datasheets:
SDS2000Xplus, SDS800X HD, SDS1000X HD, SDS7000A: 80.000
SDS3000X HD: 28.000
SDS5000Xplus, SDS6000A: 18.000
SDS2000X HD: 14.000

So the 2000X HD is the best model of all. ;)
However, I had never used the mask test to be able to judge whether the rate is really important in "real life" or only for data sheet fans.

This is still kinda confusing.

Not sure why these specs indicate the 2000X is ”the best model of all” (maybe it’s just humor?).
More importantly, while any one feature spec is just one feature spec - which may or may not be of interest to some users - this feature spec indicates that (unless it’s a documentation error) something is different about the architecture of the 2000X HD vs the product family siblings.  Maybe hardware or firmware or support or some other aspect of product development?

KungFuJosh:
It was humor. Truth be told, it probably doesn't matter for most people whether it's 10k or 100k per second on a mask test; it's just the idea that they made more expensive models with a lower spec that I can't reconcile in my head.

roger on the humor

and yes this feature spec is not a big deal

just trying to understand the “why” and if there is any notable implication for the product (especially with respect to the support road map) beyond this one feature spec

it would be nice if someone from Siglent could explain it
