RE: FNIRSI's "proof" video (I was bored and watched the BS again)--it also strikes me that a "HANMA
TEK" DSO1102 could also be a less than precision instrument--just sayin', ya' know...
But that aside, their driving both 'scopes to 25 Mhz, connected in parallel via alligator clip terminated "test" leads, invalidates in numerous ways, the entire supposed "comparison". It would be interesting (but hardly worth it) to send the blasted thing off to
Trescal or some other lab and have it tested. Maybe they'd volunteer to do it as a lark...
