Hello,
The scope is connected by ethernet in a local managed network but i have tried a direct connection using a crossover ethernet cable and it still froze. (I havnt tried serial because the whole point is to not use libraries.)
I mainly code and run the script on a windows computer but we do use Ubuntu to run the code overnight and it still hangs on those computers. (Havnt tried Mac but would expect the same results.)
Im interested too if its my code or something wrong with the scope (At this point i think both, but leaning more towards it being a problem with the scope because im missing something in my code they dont have listed.)
I have used their basic python code as a test and just replaced it with the waveform command instead of *IDN? and it still hangs. (
https://siglentna.com/application-note/open-socket-lan-python/). This code collects the waveform of the first channel 100 times.

If you know Julia i can also send a Pluto notebook but i think python is much more universal.
