learning all about de-emphasis has been really eye-opening

@miek Looks like a nice scope :)

@tnt @miek 40 GSa/s. 😳 Equivalent time sampling?
Show threadmiekApr 15
@tom_verbeure @tnt nope 😁

@miek @tnt Which model is it? I really need one, obviously.
Show threadmiekApr 15

@tom_verbeure @tnt of course! It's a DSO81204B.

Gotta be careful with them though, if you were to knock some config bits loose any model in the series might end up with 13 GHz BW accidentally 😇

@miek @tnt It’s a beautiful thing.

@miek @tnt You weren’t kidding: a 2 GHz BW DSO80204B could be upgraded to 13 GHz? That’s insane. What’s your model number?

@tom_verbeure @tnt @miek I mean, that scope doesn't look extremely high-end, but, um Lecroy and keysight both do oscilloscopes >60 GHz input bandwidth in direct sampling, R&S is at 40 GSa/s, too, and sampling rates in COTS optical modulation analyzers are 256 GSa/s…

@funkylab @tnt @miek But those are contemporary scopes. This one has the UI of my 25 year old 54831B.

@tom_verbeure @tnt @miek I mean, yes, these are Agilent-descendant knobs, but if you're going tektronik, wouldn't that put 100 GSa/s direct somewhere in the 2008/9 range (wavemaster 8zi)?
