Oscilloscope utilizing external ultra wide screen

<< < (4/4)

5U4GB:
For people saying "use the zoom on your scope", the very best zoom in the world on a poky little 7" screen is still worse than any kind of larger screen.

Why do multi-thousand-dollar scopes still use displays that would have been marginal in the 1990s?  It's like they spent tens of thousands of dollars and years of engineering time designing the best front-end they could and then when they got to the display said "get the intern to grab a $20 panel off Aliexpress and slap it in a case, that'll be good enough".

It is the other end of the market from todays cheap/disposal junk: "can you supply this exact panel (in relatively small quantities) for at least the next 10 years"

The "small" screens are usually fine for people without glasses, if you can see the pixels and a larger screen does not increase the resolution (which is true for many/most scopes) then there is no advantage to anything larger.

Another option is to buy an USB scope and use it with a normal PC. Then you can also make a little box with switches and rotary encoders, that looks and works just like the user interface of a regular scope. I find it quite weird that people who sell USB scopes do not have boxes like that as a standard option for use with their for their scope.

You can even make something like that yourself relatively easy. Just have your box emulate keystrokes to control the scope software.

Maybe its the USB interfaces fault, as there isn't something like a web browser with javascipt for USB.
With ethernet it would likely be a standard browser for the GUI, not a proprietary app. In 2009 we made a Win32 app for a Lecroy scope with a user interfaced based on a picture of the real scope, combined with digital video of the physical screen. It did not support flexible diagram size but can serve as another example of what doctorandus proposed.

So today I checked again with Tek, and I was wrong.
You can stretch app sideways a lot. Here you can see it streched between 2 screens.
Then, if that is possible it's big shame that you can't deattach one chart to separater window, or arrange views like in R&S MXO5.
