Sounds like a perfect example of where the Siglent way is going to be a pain in the ass. You'll be forever zooming in to look at detail then forgetting to zoom out again to prepare the 'scope for the next capture.

How many times do you want to post this crap? You're factually incorrect.

So why keep pushing a beginner, who asked for some clarity on the best way to use their scope, away from the way that scope is designed to be used?

Actually the question was:

I confess that i was assuming it would work more like the Keysight, which is part of why I was having trouble understanding - I hit "stop," but there was no data past the end of the screen. I think I am now understanding that, for the Siglent and a few others, what is captured is only what fits on the screen at a given moment - thus, one must zoom out, capture, then zoom in to see detail. Right? Maybe?

So there you have the proof you are so friggin' wrong in your thinking it isn't even funny, right in your face: people expect a DSO to capture beyond the screen because they find it useful. It is simple as that, like it or not. And yet you keep on going trying to push your limited view onto everyone. FFS  :palm:

The best way is what gets people to results in a way which suits them best. Imagine somebody coming along insisting you stand behind your desk while you prefer to sit on a chair behind your desk.

Here is where you are not fully conversant with Siglent DSO development, much different to how Zoom mode and memory management was implemented in the past.

Now when your fingers are on the timebase encoder Zoom mode is engaged with just a press, < not new, but toggling between windows in Zoom mode is just another press of the timebase encoder and in those models that offer memory management the main timbase can be zoomed out an order of magnitude more than most DSO's available.....while in Stop mode.

12bit SDS2000X HD, 8bit SDS5000X and all higher BW models have this capability which can negate the need for Zoom mode yet in Zoom mode the trigger point is always visible so to have a reference point when panning through a capture.

- is there a link to a video showing this? Thx

--- End quote ---
Not that I'm aware of.

Which particular features interest you ?
Will a series of detailed screenshots suffice ?

I have SDS6204A that has the memory management features which can also be used like SDS800X HD with Auto memory management. Zoom mode for both of these works the in same way.

Some people expect that...
It is not without reason that the default setting for all scopes that I know across brands is “auto” as far as memory management is concerned.
And in this setting you can't look “behind” the screen and I bet 99% of the time you don't need to, otherwise it wouldn't be a default setting.

The features you mentioned/indicated that are “much different to how Zoom mode and memory management was implemented in the past.”

I think the reason the default is auto is because that will ensure the highest waveform update rate as this is something many people find very important. Otherwise the support department will be swamped with questions. OTOH, there is no such setting on Keysight DSOs. You always get full memory for the last acquisition.

Edit: also think about why all (except for 1 or 2) major manufacturers of DSOs have been implementing capturing more than what is necessary to fill the screen for 40 years already (since the dawn of the DSO in the 1980's). If it where such an outlandisch or bad idea as some pretend it to be, then why are all the manufacturers still implementing it? Even the early Siglent scopes had capturing beyond the screen (the first firmware versions for the SDS2000 for example). It makes no sense for the oscilloscope manufacturers to implement/retain a feature without any significant demand for it.
