--- Quote from: tooki on December 26, 2023, 07:08:19 pm --- 4000G is already out, I had a quote for one back in October. But no news on any true upgrade to that hardware — 4000A->4000G is just like 3000T->3000G: basically no changes other than throwing in most of the software options by default. --- End quote --- I had no idea! And even if I do a google search, nothing comes up for the 4000G I also do not see it on German distributor sites. Is Keysight hiding their marketing for this 4000G scope? |

The lack of UI lag is one of the things I like the most about Keysight oscilloscopes, at least the ones I’ve used (which are all WinCE-based units, including older 1000-series). --- End quote --- The 1200x series (Linux) is based on same hardware as 1100x (WinCE) and FPGA binary is the same. I'd expect similar GUI performance between the two. |

The (half) built-in VNC remote control also runs at laughable frame rates like 1 or 2 fps. --- End quote --- I’m not talking about remote control (admittedly a big downside to the Keysights). Have you used other oscilloscopes? Practically all have user interfaces that are slower everywhere, all the time compared to the Keysights. Many have UIs that I consider to be unusably slow. --- End quote --- I have used many scopes, including owning MSOX3000T. MSOX3000T has very fast reaction on physical buttons and knobs. But there are also things on it that are slow. FFT is slow. Search is slow. Decode from segmented memory first time is slow. But it is definitely optimized to feel responsive on most basic manual operations. OTOH even on DS1000Z that I definitely noticed it was much slower some time than Keysight, i never felt it was unusable or that it was a problem that would prevent me to do my job. So even if you can notice something not being as fast it can still be perfectly usable. That is definitely a topic where individual preferences and usage patterns are very important. If you spend lots of time sifting through deep memory or doing FFT that might be priority for you... So yeah, that is going to be very individual opinion. Some will care very much, some not at all. |

WinCE as much as not getting much love, has that done very well. On Linux, it depends on what toolkit was used and how it was tuned. But, since Keysight has resources and if they took it as priority, I agree with you they might at least make it comparably fast. Even if not exactly the same they would tune it to be "close enough". |

FFT is slow on all 3000x, 4000x, 6000x Keysight scopes The older 7000 series like the MSO7104B is much much faster in the FFT and all other math functions. |
