And lower cost, though only after the NRE is revovered.

The other are still doing ASIC. R&S did it. Rigol did it.
It does allow absurdly powerful specs to flow down into lower market segments.

--- End quote ---
Rigol didn't, they have analog and ADC ASICs, but the waveform rendering is FPGA.

--- End quote ---

It does a bit more than that:

But in any case they invested in ASIC's which allows them to reverage the price advantage into lower market segments.

Their ASIC is only 2 chips: AFE (analog front end) and OSP chip.  OSP chip has ADC and some DSP (probably equalization and linearization of data from massive parallel ADCs).

Rest of UltraVision platform resides in normal FPGA and application processor.
What they call SPU (sampling processing unit) is actually their IP running in commercial FPGA.

WPU and CCU (Waveform plotting and central control unit) are running in application space on general purpose CPU with DSP extensions. GPU would be here and be able to contribute here.

As for Keysight, they developed loads of new ASICs for UXR series that are also used on MXR series.
It is just that it remains to be seen if they care about "low cost segment" anymore.

Like I said before, with Megazoom range, they are in the same spot as Fluke with F87V. As long as people are buying it, why invest. They might even have (actually I'm sure they do) some architecture thought out, even if no physical prototypes.
But market game is tit for tat game. You reveal your next step only when forced. In meantime you milk it...

It also allows them to flow up :) -- we released the MXO4 more than a year before the MXO5 and MXO5C.

Someone posted in another thread that we're adopting a Star Wars strategy - start with MXO4, MXO5, and MXO6, then go back and do MXO1, MXO2, and MXO3.   Can neither confirm nor deny :-DD

Correct. The point is though that most of the big companies are doing ASIC's for scopes, so it obviosuly pays them to do so.
I'd be stunned if new Keysight scopes don't have a new ASIC(s). Whether or not it's called the Megazoom V remains to be seen.

Depends on how you define the "low cost segment".
Most manufacturers seem the bring down ASIC/tech from higher end platforms down to lower end segments. Keysigh have done that before and I don't doubt they'll do it again.
Might not be right off the bat, but it will happen.

more than 13 years a long time to milk.
IIRC the interval between previous Megazoom ASIC was 8 years. So well overdue.
I doubt you'll have to wait much longer.

--- End quote ---
If I'm interpreting posts on this forum correctly, I think the Rigol DHO800/DHO900 actually do scaling of the display data to some extend when connected to an external monitor. I highly suspect Rigol is using a GPU to render the screens on these scopes instead of an FPGA. When using a GPU you get scaling (almost) for free.

I believe that just a standard android O/S scaling, it's not the actual waveform data in any way.

--- End quote ---
In that case I don't quite get what you are after. Do you mean you can get more information? Like more measurement positions? More horizontal divisions?

--- End quote ---

Yes, more division and/or more data physically plotted because you have more pixels.
Even if you keep the same number of divisions, if you have a higher resolution screen you have more pixels per division with which to plot data.
jusaca:
I actually get the impression Keysight is not really interested in the mid range market anymore so they concentrate on the high-margin, high-end products. Rigol and Siglent delivering quite a decent performance in the mid-range for a comparatively low price is probably destroying the margin for the production prices Keysight can achieve.

You can see this in a lot of areas. Established companies leaving the entry market to newcomers because margin just isn't interesting anymore, compared to devices being sold for a complete magnitude higher up the price range.
