Where is the Keysight Megazoom V ASIC?

jc101:
My biggest issue with Keysight is the move to renting the hardware features.

For example, the E36731A Battery Emulator and Profiler is a PSU and electronic load you can drive perfectly from the front panel. However, to use the Battery Emulation side, you need to obtain a licence for BenchVue, as it can only be driven from the PC. The licence is rented annually. You can also now get a node-locked permanent licence for an additional 30% on top of the instrument price to use a feature screen printed onto the front panel of the device.  You buy the hardware but can only use 2/3 of it until you pay them again for the remaining 1/3.  They would have sold one if it weren't for the ridiculous cost of the licence to be able to actually use it.

I love my Keysight 3000T.  It responds instantaneously to input and can decode almost anything I need to decode.

a few days ago Daniel shared on twitter a very zoomed in picture of an instrument's footy thing, https://twitter.com/DanielBogdanoff/status/1793780675319103801

my hypothesis is that it being all zoomed in might be a hint of Megazoom V

However ASICs can not use the high end processes as FPGAs due to the very high mask costs. So the advantage is getting smaller and smaller - if there is any left at all.

Nowadays using a GPU for doing all the heavy lifting is a good choice for building a DSO. Performance, power consumption, production cost, software development cost and flexibility wise there is no match.

GPU is in a wrong place in a data graph to replace FPGA. Megazoom is ADC/trigger/sample memory part. GPU can handle screen rendering, phosphorus emulation, math and measurements acceleration etc. So it just makes application processor really fast, basically bringing processing power of PC scope into realm of embedded scopes.
But ADC-FPGA in front of it stays.

And even Keysights with Megazooms have FPGA too.. For accelerating and implementation of other stuff Megazoom cannot do.
So you just put bigger modern FPGA and you don't need Megazoom anymore.

GPU is pretty much useless for what Megazoom ASIC does. The problem is not CPU or graphical processing power.
