You can copy signal settings to trigger for easy basic setup-
Then go to: Trigger : CAN setting: ConditionCould you explain this a bit more precise? What signal settings?
The manual is not so good about this topic.
Dang, can't get a SDS804X-HD in Canada until early May. One supplier (of the two official outlets) is offering me a price of $389USD if I pay today for a burger I get in May. Do I trust them?? Not my usual source so a little leery.A $50 saving is a $50 saving......unless they have their pricing wrong.
Ask for this price in writing for a May ETA and delivery costs.
Will nearly be May before we get any of the new HD scopes.Yeah $50 is $50 (more so in CAD) and they are a listed vendor. Just that RCC (my usual vendor) have been an excellent "partner". When I had a problem with my DC load they did a cross ship for me. That's above and beyond. And when I had an off-set issue with my SDS1104X-E they offered to forward it the Siglent NA for me saving me a ton on shipping.
I think I'll just wait and deal with RCC. They have been great so far and seem a little bit less desperate.
It would help, if you would use some more words.
I cant filter the for a range of CAN IDs for the trigger... No way!
Its the trigger
I cant filter the for a range of CAN IDs for the trigger...
I find this pretty clear: In the CAN protocol trigger condition, you can either define a single ID to cause a trigger, or you can select all (any) IDs. You cannot define a range of message IDs which cause a trigger -- which may be limiting, depending on your system under test.
What other information were you looking for, Martin?
I don't think it is possible to circumvent this by copying CAN decoder settings to the trigger settings.
What exactly other scope can do and in what form? What is exactly function that sems to be missiing?
Does anybody know what the FFT update rate is like? Especially compared to the SDS1104X-E?
The SDS800X HD is smoother than the SDS1104X-E.
What is the purpose of this question? If you are just deciding which product to choose, you are definitely choosing the SDS800X HD.
If you focus on this performance, my opinion is that functional correctness and stability are much more important than speed.

Well if I'm measuring a signal whose spectral content changes over time, and I want to see how, then the faster the FFT updates, the better.
Ahh, well recently I had a sporadic tone superimposed on some audio being produced by a circuit I was working on, and I wanted to determine at what frequency it was at. I didn't have a way to setup the scope to trigger a single shot capture the waveform when the tone appeared, and it often appeared and disappeared too quickly for me to manually stop the capture so that I could compute the FFT. So if I had a fast free running FFT, I could just monitor the spectrum and watch for where the tone spike appeared. There are probably much better ways of solving this problem, but honestly, if I had to choose between an FFT update rate of 1Hz vs 10Hz, I'd always choose the 10Hz update rate. Maybe not so much of a "need" but more of a "want".
Well the FFT computation speed probably isn't data dependent, so the specific signal doesn't matter, too much, but it would be neat to see visually what the update rate is at 1M points. (When I get one, I'll probably make a video about it and post it here).
As an aside, I think the Rigol DHO800 also has a software based FFT, but it's significantly faster than that of the SDS1104X-E, as can be seen in one of Dave's videos.
I guess the question about "specific test signals and what kind of results you would like to see?" was more meant as "what signal are you looking at where eyeballing a fast-changing FFT is what you need as a readout?"

It seems, that you havent done much with CAN bus. There are many IDs, that fly through the bus. If you want to watch just 2, you cant do this! That bad rigol could filter this as i would expect it in such a price range, but the rest after it is terrrible!

They listen to good input. but it has to be well explained.
If you want help, please explain in detail what exactly Rigol has ( explain how it works and what it does on that scope) and where it is and details how Rigol implemented that feature that you seem to like.
The first point is that the Rigol 800s do not have CAN decoding.

Let me try again...
I have a lot of IDs in the CAN bus. From those i only want to see (trigger on) ID 1776 - 1789. With the Rigol you could write a X, which served as a wildcard. In binary, decimal and hex. So you could not only filter ids, but also the data bytes!
I always wonder why some can create such a feature, but then forget (?) essential things. Try getting a frame that has that one wrong byte...
The first point is that the Rigol 800s do not have CAN decoding.
Are you talking about the DHO800?
If yes, why would you say so?
Because the DHO800 series has no CAN decoding.
The 900 series has it .
Sorry...SORRY, my fault...
For whatever reason I thought the opposite, even though I had an 800.
