Only a some UI changes. All the necessary logic to support zoom-out is allready there. Go sit behind a DSO and enable zoom-mode. You can scroll left/right / change the timebase of the main window without any problem. Now imagine doing the same with the zoom window hidden. What is functionally different? You keep thinking it is a major overhaul and months of work but it isn't. Most of the work is likely for someone at Siglent to change his/her mind and to realise that zoom-out is a standard feature on every DSO of their competitors. |

Siglent and Lecroy are the outliers who don't have it. --- End quote --- Agilent Infiniivision series DOESN'T have it, the way you like it. While in a run mode, it grabs only screen full of data from trigger to trigger. On some timebases it will grab a bit more but far from whole memory. And when you press Stop, it makes separate Single capture for the last one if there is triggerable event within 200-250ms (or so) from moment you press Stop. If not, you are left with only screen full of data. I already demonstrated that before and documented it into detail. So, no, Keysight doesn't do it. Please everybody stop repeating that, it is not truth. Regards, |

You said it was a sign of quality, and that Chinese manufacturers should test better. I don't know how big overhaul this would be, as I know how software is written. But I do think it is MAJOR change in the core of the system (what is scope of data for measurement? Zoom, gates, full buffer ?) If they do change this ( and I hope they DO ), I would WANT them to do it right and to test the crap out of it... And zoom out doesn't exist. Competition have one memory strategy (that by the way is reason people say Tektronix scopes are slow, because they set it to 10Ms depth and then go: "Boy this thing is slow, cannot make more than few hundred triggers per minute..."). "Zoom out" is artefact that your scope captured more data than you originally set it to show on screen. Rigol, by default, doesn't use that strategy, but uses same one as Keysight and Siglent, and Lecroy.. But Rigol has advantage that you can enable full memory, so user can choose. I hope Siglent will add it too, if for nothing else to end this endless, repetitive dejavu.... |

I claim it is simple to add and now you jump to testing??? It makes no sense at all. 'Zoom out' is simple to add so it is simple to test. You keep grasping straws to justify 'zoom out' is difficult to add. With my software engineering hat on and knowledge about oscilloscope memory management I say it isn't difficult to add because I KNOW it isn't. |
