Maybe they are concentrating more on the high end UXR scopes. --- End quote --- No I do not see anything wrong with Keysight. They just recently sent me an invite to their webinar "How to protect your satellite network". Very useful. :-DD |

The advantage of an ASIC over an FPGA is possibly lower power consumption at the same performance. --- End quote --- And lower cost, though only after the NRE is revovered. --- End quote --- 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: https://www.rigolna.com/UltraVisionII/ But in any case they invested in ASIC's which allows them to reverage the price advantage into lower market segments. |

One possible innovation here would be to actually scale the waveform data if you connect an external monitor. No other scope has that. --- 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. |

Do you mean you can get more information? Like more measurement positions? More horizontal divisions? |
