University professor here: showing and decoding wire signals has become a staple in my teaching - very effective, eye-opening even for students that find the OSI layers too abstract to grasp on paper. Btw, I’m using this nice demo board (I’m not affiliated with the brand): https://www.batronix.com/shop/demoboards/Batronix-MSO-Demo-B...

…typically we decode I2C.

Oh, I‘ve equipped the lab with all kinds of oscilloscopes. I find a lower mid-tier product (like Rigol DHO 900/1000 series) most suitable: good enough resolution and nice quality-of-life features (many physical buttons / dials and input channels go a long way!), yet not too feature-packed and physically compact to still be approachable.

Interesting.

Do you happen to know if that batronix board useful to have even if you have a Rigol DHO 924S without the logic probe (PLA2216)?

Yes, it’s absolutely useful. You need the logic probe (which I do have, but never use in „standard“ teaching) only if you plan (or need) to monitor more input signals than the analog ones on the scope.

In fact, to demonstrate the very physical foundation of digital computing, it is very useful to use the analog inputs and zoom all the way in to see the slight imperfections in signal transmission.

Thank you!
