As an example the specs on this look adequate for troubleshooting I2C
waveforms.

I find the test equipment available nowadays truly amazing and
especially at that price... However my old stuff from ~30 years ago
still works (some pots and switches could use cleaning) and I wonder
how long these new items will last. Of course if they were to work for
another 20 years I'll not likely be around to complain about it?

 I picked up a cheap portable storage scome (single chanel only) for
that kind of work then stumpled across a primo   Tektronics 465 with
the DM44 add-on for $50. I had been scopeless for a couple decades
since my old Heathkit blew a couple capacitors (with a big bang and
lots of smoke)
 Picker it up to do some automotive electronic troubleshooting - and
made a pressure pulse sensor for it as well.
