Looking guidance on how to further carrier and to select O-Scope
I am from CS background, after writing embedded firmware and stuff on breadboard for sometime. I have been learning electronics, for now basics and putting together modules and laying out PCBs lately, mostly studying, altering and copying reference schematics. Occasionally reading app notes to grasp concepts. I did 2 Rf Pcb and got them reviewed, but I feel it was more of luck or simplicity that made them work. Now I want to approach things like a professional and do it as a part time gig. I understand that I need to learn a lot more, especially debugging tools and their uses to design good PCBs, especially those that involve say higher power RF, dc converters, some flash and sensitive analogs on the same board. So I put together one PCB for a client which had all these, but before submitting I wanted to know if the quality is good or not. So I got some pointers and test ideas from ChatGPT (as range didn't seem good). I realized I need a good scope, other than those 200khz adc knock offs. At the same time I don't want to invest heavily into equipment until this gig kicks off.
So here I am looking for suggestions, what my course of action should be, to estimate the learning curve and finally what scope is recommended. Especially to see power transients, ground bounce, emi emc issues.
My current project involves 1 watt (vhf) Rf module, pi pico, buck boost converter, and charger ic. But my scope for other projects might vary. I really like learning, sort of hobby, so I try not to limit myself. Any suggestions are most welcome. DMs are open too.
Thank you, have a very good day !
