The beauty of dso is, you can change nearly everything in firmware.
So, in case of siglent, why don´t change the memory management, letting the user allow to choose for himself always the maximum memory - or choosing it to auto.
They do.. from their own workflow its fine as it is and even with my own now that i know how it works, its just that everyone else whom dont understand how to use the zoom control to control it.. and thats a great deal of people
Nonsense. Zoom mode just wastes precious space when you need to set it to the full memory depth in order to force an oscilloscope to use all the memory. There is nu useful information in there to have it on screen. Search and (when decoding) the list with decoded packages are way more useful navigation tools. And using the decoded list view in turn requires to do full memory decoding and not just what is on screen.
Again you use wording that makes it look like you insist that people are stupid if they don't think like you.
Zoom is useful, and navigational clues and buffer position are crucial piece of it. You just dislike it. On your R&S with large screen and freely configurable zoom size, it well worth the screen space it uses. On Picoscope with excellent zoom implementation it doesn't even use additional screen space at all. It is very easy and intuitive to use.
Try using your web browser on pc without scroll bars... You think people invented dozens of navigation tools in GUIs because they are stupid?
You keep applying fact that "zoom out" is useful for a special case (long, slow triggering captures where you need to get long sequence but need to look at on short packet to know when to stop) and apply it as a general principle.
Get a grip. Zoom out
can be useful.
We all agree to that by now.
Is it necessary ?
No it is not. Very few people use it in isolated situations, and you can as well accomplish same results using zoom mode and/or propper timebase settings.
Comfort of any work procedure
is highly individual thing.
Should Siglent add full manual control of acquisition memory like R&S has?
Yes by all means, if they can. It is
ALWAYS better to have
more options. I still would like if they would make
zoom mode more configurable to be able to use less screen space
as I would rather use that. It is more logical and straightforward to me. And any user of Picoscope and LeCroy.
Would I refuse to buy LeCroy or Siglent scope because of that? No, not by a long shot. I bought Picoscopes despite that, because it is unimportant to me. I just use zoom mode when I need to capture long and look at short time. Period.
What bothers me a bit are these overblown overtones in how this, frankly, non issue, is presented here.
I have an urgent message to Siglent: Please issue urgent firmware update in which in all menus and user manuals you rename memory depth options so it is clear memory management is Auto with max length.
Because that is only mistake they made. Unclear terminology. Everything else is one man on a crusade, and a bit of clickbait titles on some videos.
If you guys want to give Siglent (or any other manufacturers) a grief, then please apply energy to get them to fix real problems, real bugs or add real, useful, features.
For instance Nico says his prefered method to navigate through capture when decoding is to use list or search.
So why he didn't write an write up how
R&S RTM3000 (that is very expensive)
doesn't have search on most basic I2C, SPI or UART protocols. After few years since it is released, still doesn't and
not a peep from R&S
they even have intention to do so.
NOW,
that is a serious problem, and a
reason I
didn't buy RTM 3000 at the time . It was
otherwise my
first choice.
Try finding one packet in 10000 manually.
GW Instek has it, Keysight has it on 3000T series and up, Lecroy has it...
That is an example of real reason not to buy that scope, not some buffer management strategy that you might need in obscure workflow that is applicable only now and then.
And my reason why I didn't buy SDS5000X so far is the same. No search on decoded data. You want to give grief to Siglent, bug them about that.
And to make decoding to decode full buffer length, not only what is shown, with and without zoom mode. That is useful. I agree with you Nico on that. That is something Picoscope does right..
Best regards to all..
