I came across this video from Yokogawa. It was apparently a livestream showcasing their new 12 bit DLM5000HD scopes:
There doesn't seem to be much about yokogawa scopes out there, much less of these 12 bit ones. Are they only big in japan? i really like their scope design, and they seem to be pretty high end, like on par with Rohde & Schwarz/Keysight/Tek, but they also seem to be pretty obscure, at least in the english-speaking world, why is that? hmmm!
Anyway, this scope looks really cool, too bad that they streamed from like 2005 and so you can't see too much of the 12 bit-ness in the video
