First, cudos to Tek for finally coming up with a scope that is not just a rehash of their old lacklustre DPO/MDO platform. It's nice to see quite a bit of innovation in the new scope, and we have a (niche) task where the new MDO5 could serve well.
However, I also have to agree with Dave and others that Marketing went overboard, unfortunately as usual with Tek (not that Keysight and R&S don't suffer from the same illness, they're both similarly bad). I know there's a widespread believe that scopes like these are bought by MBA'd office monkeys who have no clue about how to use it, but reality is that it's generally engineers who specify and request a specific instrument. Exaggerations like "game changing" or "this changes everything" make a manufacturer look pretty silly, even more so when wrongly claiming firsts, and frankly if a manufacturer spends so much time talking (usually through their asses) about its competition's scopes instead of its own product then it makes this manufacturer look desperate as well, all which take away from a product which, if it's any good, should be able to stand on its own. If it doesn't then, well, it may be that the product isn't as good as you thought it is.
Now to the "game changer" scope:
I like the format, I like the design, and the large high resultion screen is nice (I don't think it makes a huge difference but there's certainly the argument why a $15k+ scope needs to come with low res panel in this day and age). Also the choice of Windows or some embedded OS is interesting and probably helps in areas where classification of test data is an issue. The 12bit vertical resolution is nice, too, despite the ENOB (which is pretty meaningless anyways without knowing how it was derived).
Connecting the digital channels to the main ADCs is an interesting concept which gives more flexibility although it might create 'either/or' situations where analog and digital channels fight for an ADC.
However, based on what I saw from the videos I watched, I do have to say the UI is really poor. It might have been designed for touch as claimed, but considering that Tek is late in this regard I think the result isn't exactly stellar. It looks like it has been designed by someone who has very little idea about human factors interaction. Some of the actions seem unnecessary convoluted and illogical (i.e. switching off a channel by dragging it to the recycle bin???). Considering that LeCroy had it's touch-designed MAUI for roughly 15 years, and by now even Keysight has turned the original mouse-driven UI of its Infiniium scopes into a proper touch UI, I would have expected something more, even though it's already a big step up from the horrible UI of the MDOxxxx Series.
I'm also not sure how useful an AWG is in a scope of this class, especially when it comes with limited BW (50Mhz) and tiny sample memory.
Also, it seems Tek hasn't really clearly thought about the markets at which to aim the new scope:
Why someone should buy an 8 channel scope? The main applications are power and motor control (3 phase).
Who would use a 2Ghz scope for these apps???
This. The main application for 8 channel scopes are power/motor control application, which generally are fine with BW of 500Mhz to 1GHz. Pretty much all 8 ch scopes are aimed for that market segment, which is why they all come with some kind of power analysis tools. Something that doesn't even seem to be available for the Tek MSO5x.
In fact, the overall list of options for the MDO5x is pretty sparse: some jitter analysis package, and serial decode package supporting a few standards (I2C/I2S, SPI, UART, USB2 (but no HS mode), Ethernet, CAN, LIN, FlexRay, TDM) seems to be all that's available. The LeCroy HDO8kA's option list offers a long list of serial decode standards as well as packages for power analysis, compliance, EMC, Serial Data Analysis and even Vector Signal Analysis. As to four channel scopes, Keysight's DSO-S comes with an option list that has even more serial decode standards plus several analysis packages. Which is no surprise, because in this scope class application-specific options are crucial and make or break a scope.
So where does this leave Tek? The MSO58 is an 8 channel scope that doesn't support the main application for which 8 channel scopes even exist. The four channel MSO54 still lacks most of the capabilities of its competitors. Up to 64 digital channels are nice, and an 8ch MSO58 can have 4 analog and 32 digital channels which is more than other scopes, however applications requiring a 32bit wide MSO are certainly a tiny niche, and again the lack of options will leave the Tek MDO5x exposed.
The AWG, not only because of it's low specs, seems to be more like a gimmick. The same is true for the DVM, and considering the UI I'm inclined to say the same about the high res display. AWG and DVM may be useful in entry-level scopes but I can see little purpose for them in a lower high-end scope.
I also wish Tek had put some of the effort they used for exaggerating into making its datasheets better, or why is basic performance data like max FFT sample size, the AWGs sample memory size or the AWG resolution absent?
If the waveform update rate of the Lecroy and Keysight is low then you may not capture glitches for a long time.
I'm not sure how Tek did its "tests" (or how competent the tester was with a non-Tek scope), and of course Tek doesn't state the test parameters or even the software versions of the involved scopes, but we get a lot more than the claimed 700 wfms/s from our HDO8000 (non-A) scopes, and even our Keysight scopes fare better than the 1000(?) or so wfms/s stated by Tek.
I'll certainly get a demo unit in at some point for our engineers to look at but aside from one niche case where the high number of digital channels might be useful I can't see how the MDO5x could even replace our Keysight and LeCroy scopes, forget about "changing everything". However if Tek works on expanding the options (maybe start with power analysis) then it could become a viable alternative to Yokogawa, LeCroy and Keysight, though.
