Once you have basic understanding of how the scope works and is set up, it's limitations, then you need some experience using it along with the understanding of what and how you are measuring the circuit. Without the electronics knowledge background the instrument can quickly become nothing more than a boat anchor.
Trying to find missing steps cans really be a challenge, for instance, relative to software one would need to ask......
What am i measuring?
Is the software at fault, motherboard, port, something in between or along the way........
How do i isolate the circuit for sampling
Is my scope adequate to do the job......
So echoing what was said........... beyond the scope of this forum.
