In Siglent's defense: the more recent models do support setting the memory length regardless it is more than needed to fill the display. Siglent finally woke up after Dave's video. So you'd have to check the model and firmware version.

Why are you claiming things that are not true?
Where did you get this information?

Yes, exactly, because a forum operator had made a video and a handful of forum users blew the same horn, saying that it was really important to be able to do that, so Siglent woke up and gave the few people what they wanted.
I would think about that again.
Perhaps look into when and with which models this is possible and what these models have in common.
A little hint, this has something to do with a (math) function that did not previously exist in Siglent scopes.

You may say it caters to a few people but then explain me this: All DSOs from many different brands I have owned and many which I used, supported capturing beyond what is needed to fill the screen (including the Siglent SDS2000 with the initial firmware but except Lecroy). Even my Tektronix 2230 from the 1980's had capturing beyond the screen. You can not convince me that oscilloscope manufacters from all over the world have been putting a feature in their equipment for about 40 years which only very few users find important. It just doesn't make sense.

Also keep in mind that EEVblog only has a very small number of EEs taking part. EEVblog is nowhere near representative where it comes to test equipment users or EEs in general. 9 out of 10 EEs I talk to never heard about EEVblog. Then again, Siglent seems to be quite interested in Dave's videos and sends him their equipment to test regulary. So it is reasonable to assume Siglent takes note of Dave's findings. OTOH test equipment manufacturers which have been around for a couple of decades already have a much better view on what is important to their customers and implement (=spend money on) features accordingly. Take a modern DSO from R&S or Tektronix for example, they all allow to set & use the maximum memory length even though these are new designs. That is no accident for sure!

As was previously said, SOME scope models from SOME brands do that, including Siglent. I don't see the point in this discussion at all.
