The ADALM2000 activity https://www.analog.com/en/resources/analog-dialogue/studentzone/studentzone-april-2022.html is missing the Appendix part list for the third section, in particular for matched optocouplers.

Hi mzaffalon , thanks for pointing this out.
It looks like the appendix from the original lab writeup got omitted:

You can buy dual PD optocouplers that have guaranteed matching specs, but they're not very common:
