Hello,
I recently got my hands on a Siglent SDS2104X Plus. Now I tried whether
it would be supported by Sigrok. It doesn't work right out of the box
but with some small modifications (see attached patch), I was able to
get some responses from the scope and at least a partial wave form. But
it stopped after maybe half of the screen.
Before I analyze whether that is some protocol problem, I want to start
with the basics: The configuration structures changed in my hacked
together patch. Currently I just copied the values from the SDS2000
series (without "Plus"). Most likely that's not correct.
Is there some guide or some hints (like notes for porting an older
Siglent model) that I could use as a starting point to find out what the
values mean and determine the right values for my scope?
Best regards
Christian
