Instead of focusing on how much better the current generation cheap scopes are or how expensive some other options are, why not accept that things are not perfect just yet? The decoding options are lacking. Simple as that.
The ability to do a fast trigger on the data values of a decoded stream might require some decoding in hardware. However even so the trigger options are quite limited. Everything else could be done in software using free open source decoding libraries. We could even have software triggers, that would maybe not catch every single event, but be good enough for many purposes. There is so much that could be done here.
When it comes to slow ass protocols such as 5 Mbps CAN - any CPU even a MCU can do that in software and catch everything. The "can only be done in hardware" is simply not true in these cases.
I hear people are playing with making Android apps for the Rigol scopes. Maybe we will get open source apps that can do this stuff in a serious way.
That explains things.
You live in virtual world where everything is possible. If your software needs 128TB of RAM and 256 core processor, you deadly seriously coldly "order" customer to buy better computer. ...
But if and when I need to do more serious digital data analysis, I don't plan to buy the logic analyser probe for the SDS800, but a separate USB logic analyser.
I went back late in the evening and made the little video, and the only thing you say about it is that "my task" was too easy.
Thanks for nothing.
I think this discussion will work better if we can leave the judgement of personal background and qualification out of it.
The maximum frame limit for decoding should be written in the data sheet.

I agree with what you said about the imperfect product, but I don't quite agree with the rest.
Because it is closely related to the product price and positioning.
If the price is high, the hardware will be better used, which provides the possibility for future feature expansion.
The software support for decoding and searching you mentioned is the "SignalScan" function provided by Lecroy, which is very expensive to buy alone. Even if the siglent is implemented, based on product positioning, it is likely that it will not be supported on SDS800X HD, but only on their high-end products. So whether the FPGA resources are sufficient determines the CAN ID “filtering” function, and the FPGA resources are closely related to the price.

However, I don't want to rule out the possibility that the 15000 can also be reached by the 800X HD at SPI, as I only have this one demo signal which is subject to corresponding limitations.

You may want to dismount that horse you are riding there! If you cant find good arguments about or against technical details, and just throw prices at others, then please do not consider ever answering my post again!
I showed you those files, that i cant extract with scrolling and saving. And this scrolling and saving is EASY to realize in software.
If even those expensive pieces cant do this job, then i am happy to not have bought one of those...
None of them can do that.
It seems to me, that you probably own an expensive scope, and you dont want others to do the same with their 600€ scope, that you can do with your big bucks scope.

Yes, because no one implemented that feature properly, or has just limited it big time.

Exactly 14 years ago I bought my first private DSO, finally they were affordable for hobbyists.
You can't expect a €500 scope to do everything that a €20000 scope can do and just as well.
Are you sure you would have to actually pay in advance, because in my case, although they have my order and credit card information, they do not charge the card until the order ships.

The hardware is good enough as it is. You can already decode in software, but they have just not made it convenient to do so. You can catch a large number of frames and then download this to your computer. Then use open source Sigrok https://sigrok.org/ to decode more than 130 protocols.
Yes I understand that Siglent might be avoiding this solution because the product might become "too good". But what if Rigol did it? Or it became possible on the Rigol through third part open source apps? They might be forced to reconsider. The hardware is ready. It is just an artificial limitation.
Not 100% sure but that's what the guy on the phone said, but RCC do not charge for shipping and Electro-Meters do. So it ends up being a wash on the cost.
Is there a way to access the files in the scope through LAN or USB? I havent find a way. The manual does say usb can used for connectivity, but thats about it...

I am not sure if it is also in 800X-HD.
