Hello.
To start testing the various devices and superguns I have, I purchased an oscilloscope (entirely the fault of everyone on this thread https://www.arcade-projects.com/threads/testing-bnc-and-vga-cable-voltage-and-resistance.16850/)!
I read, however, that a 75ohm BNC input from the supergun/consoles is not good for the scope, as it has a 1 Mohm connection and could reflect back to the source, which is not good for that either. I have seen the RetroRGB videos and other information online but nothing specific (or understandable) in answering the question of: what is the best way to connect and terminate BNC cables from arcade/console equipment that are typically 75ohm?
Does anyone have a clear answer or link to an answer (assume I know nothing about oscilloscopes/testing of this nature...which would be an entirely accurate assumption).
For reference, the scope is this one (but i understand this question applies to most/all others). I noticed this scope does not have the option to change input from 1M ohm to 50 ohm...it is 1M ohm only: https://www.iti.iwatsu.co.jp/en/products/ds/ds5500a/ds5500a_ds5400_top_e.html
Thanks
