It's also has the highest waveform capture rate (>500,000 wfms/sec) scope on the market with vertical resolution higher than an 8-bit ADC. (other 10-bit or 12-bit scopes don't specify capture rate and are under 1,000 wfms/sec)
This is a pretty big deal, if it's true that brand-K and brand-L scopes don't offer fast updates at all in scopes of this class. I wasn't aware of that little tidbit when I complained about the separate FastAcq mode earlier.
Very impressed with the UI as seen on Shahriar's preview video. It appears responsive, well-thought-out, and innovative without being
too innovative. The multiple-OS strategy seems smart as well. It lessens Tek's dependence on a platform run by people who don't have their users' interests at heart.
Finally, I disagree with Dave's criticism of the MSO implementation; it seems pretty elegant to me. I use an MSO that can display 16 digital and 4 analog channels concurrently, but historically I've never needed to use them all at once like that. I do agree with Dave that it was lame not to include at least a couple of 8-channel MSO probes, given the instrument's pricing. And I think he's right in that this decision will eventually be revisited.
Overall, the new scope lineup is enough of a departure from Tektronix's previous midrange models that I don't think it's unreasonable to call it "game changing." It's a game-changer for them, and by dint of their influence on the industry as a whole, that makes it a game-changer for everybody else. It's the first Tek scope that I've drooled over in a very long time.
