Is this product a BS didn't it?

vaualbus:
I watched last week this video
and I was already convinced that the device was a scam. How you test an USB3 cable and produce "eye diagram" without at least a fast FPGA and fast ADC/DAC on which I would assume you need a pretty big heatsink?
I recall I went to a keysight meeting a while ago where they show their at the time top of the line scopes (63Ghz @80 Gbs/s or what was) doing automatically validation and compliance test on USB3 buses, that is what you need  :-DD
So I guess that machine is trying to do a frequency analyzes of the cable and match the results against a know database? And produce "fake" eye diagram?
Your opinion is appreciate because I got already angry on the "wrong" eye diagram definition that was given on the vide.

wraper:
You don't need some super fast ADC for something like that. Working as sampling scope is more that enough for such application.

vaualbus:
Still you do sampling ok, but can you characterize 10gbs lines? You have to at least generate such PRBS sequence?

you can probably do that with just the phy for the various standards

As clever as Linus is, he is NOT an electronics or test eqt channel, and were I him, I'd surely delegate that kind of approval to someone live Dave, or countless members here.
