Another marketing dept has lost it

to show 4096 levels you need a vertical resolution of 4096 pixels.... Not even a 4k display has that!

Or simply use the Zoom and Pan touch function.

That works as well... forgot about the ubiquitous zoom function...

Just a little comment:

I don't feel that we can actually tell the difference between 12 bits of vertical resolution

The vertical resolution is important if you go for signal-processing. If you want to FFT your time-domain-signal for example.

Well then spend a little more and go buy a MDO or spectrum analyzer.

I don't know the meaning of MDO (and google doesn't either). But, as for a spekki if you want to watch a single-event in frequency-domain, a classic spectrum-analyzer is not helpful. The combination of scope-trigger-fct. and signal-processing can be important for a couple of applications.

If you don't need it, don't buy it.

I quite like the advert.  At least it's short & gets people talking...

It is the abbreviation for a Mixed Domain Oscilloscope
like the MDO4000 series from TEK

Thanks
I didn't know something like this existed.
But that's basically a 2 in 1 solution like a Scopemeter?!

Here's a Lecroy video about the 12 bit with some examples - not sure who the video is aimed at,  but anyway skip to ~4m for examples of 8 bit vs 12 bit;  But I'd prefer a 12 bit over 8 bit any day if given the option to buy one! (and the cash)   One Lecroy video I saw you can spin the screen 90 degrees into portrait mode, which would probably make your 12 bit waveform look better - other than that you'd have to use zoom and pan.

No it's not a simple 2 in 1 solution like to combine
a scope with an arbitrary waveform generator in one box.
With a MDO you can work with the two domains
time and frequency at a time-correlated base.

There is an good example video on Alans YouTube Channel



and Daves review

I see now. I however, do need help understanding when this is helpful. From what I see, most of what was demonstrated wa not a use of the 12 bits, but mainly a lower noise floor. The clearest advantage I see is the measurement accuracy.

While Tektronix low end scopes are absolute shit nowadays, I still think that they have the nicest marketing videos.. Relatively subtle, not all that pushy and intent on destroying their competitors like Agilent, but still not stupid like Rigol or Lecroy.

When you want to sell obsolete technology, you need good marketing department... BTW that LeCroy guy is adorable.

[Hydrawerk]

You have probably seen these commercials. They are from 2011.

[Bored@Work]

BTW that LeCroy guy adorable.

Either he did ride the short bus to school or he got some bad weed in Colorado.

Probably the short bus. Perhaps he was visiting Agilent's cal lab and they decided to give him some weed for the promotional video they knew was coming up...

Thank you for the Videos.
Now I understand what they mean with "Mixed domain". That's a TEK-only Marketing-Term, isn't it?
I used similar Instruments (especially Analyzer with Spectrogram), but without a scope... RF only. A syncronized scope-channel may come in quite handy.

Btw, I tested some these big LeCroy scopes some time ago, they are quite good despite the rather cheesy spot
But that are not the typical Hobby-Scopes. If you want that, you have an application that demands it.

Meaning: 12 Bit are nice. For several applications with post-processing of the waveform it may be a killer.(*) But most of the application of a scope don't demand them, 8 Bit are OK. In the marketing (as always) they boost the importance as world-moving or whatever

(*)Of course depending on the analog performance of the front-end. Who needs a 24Bit ADC if the first 20 are noise?

[PChi]

Thanks for posting the link to the video. Whoose doing that, Agilent as well.
The increased resolution can be useful for looking at low level signals in the prescence of larger ones assuming that the display can be made to expand just part of vertical range.
The rate of A/D converter development is so fast that I think that in a few years 12 bit Oscilloscopes will become the norm.

[echen1024]

And the pothead shows up again! I love how the oscilloscope is displaying a whole bunch of signals without anything plugged in.

[Kjelt]

Who's buyin' that? 

[Hydrawerk]

I love him.

Of course you do. Danaher starves companies of R&D and gives their managers big bonuses and sales departments big budgets.

This one actually made me laugh. By far not the worst marketing video ever, but goodness, what do they think? Oh yeah, gonna sell more scopes by making ourselves look like complete idiots who can barely put together a video.

That was just dreadful. I will take a dozen stoned LeCroy dudes over this horrible fart.

[echen1024]

This was just pure cringe throughout the video. God, at least they could have showed and actual person playing soccer with a Tek, and gotten rid of the silly finger.

[BeerCannon]

I was waiting for the guy to twerk up against that scope.. after all, who's doin' that?

[echen1024]

Out of all the things you can twerk against... oscilloscopes? I think a Logic Analyzer would be a better choice

[SpectrHz]

Oh wow. That was spectacularly cringe-worthy. Who does lecroy think they are selling these precision measurement devices to anyway?
