I have now exported the list of 115 decoded frames(csv), if that is what you meant, it was no big deal.
I have to laugh about myself. That task i gave you was too easy.
Working a bit to much, i guess.
My problem is, that when i use 500k CAN speed, with 1s/div (max timebase to capture for that rate), i can only export 2000 entries, which are also corrupted (the shown data only), if you set the timebase above 100ms/div. Only 2000 frames is quite poor in my opinion, since we are talking here about ~ 20kb. And it should decode properly, what ever the zoom is, because one might think that this data is corrupted in reallity! That sends you far on the wrong track. A device for over 500 bucks should not show complete wrong data.
In other words:
I need to be able to capture and export 20.000 CAN frames (in 10s) with a range of IDs (they can be filtered out on export in this case, additionally to the trigger mask).
Another thing:
After a crash, i was was trying (thinking) to reload a waveform, thinking "ah no problem, i can just reload the waveform and decode it again". I was dissapointed.
This would be a really nice feature, since sometimes you also hit the wrong button, and loose that waveform.
I went and took a look at your post history.
Now it is clear to me that you are complete beginner in this whole oscilloscope thing.
I'm not going to spend time explaining why your expectations are unrealistic, just simply state that they are.
Let just put it simply: your expectations are unrealistic. Even on many scopes costing 50x more.
And 500€ scope is very inexpensive. Until 10 years ago scopes that could to 10% of what it does used to start at 5000 USD price.
To put things in perspective, one (1, single) Keysight N2873A passive probe that came with my MSOX3104T has a retail price of 558 €. A single probe.
And no, MSOX3104T (a 12000€ MSRP scope when was new) can do maybe 1000 CAN packets at your specification.
And if you asked here what tool to buy for this CAN task you do, we would tell you to get some kind of CAN analyzer (something like Vector or Kvaser).
Or Picoscope, but not the cheapest one. I can do what you ask on a Pico 3406D that has 512Mpt memory, and cost €2405..
But that Picoscope is USB scope that is also missing other stuff, like any type of triggering on serial protocols etc.
But for this job of yours it would work.
