Really you have no idea what features are in the modern DSO, none at all !
Minus is a very common Math function and Invert is a channel menu feature both of which are top level menu items in their respective places.........NOT front panel buttons or switches !
Further these 2 functions (Minus Math and Invert) appear in channel tabs plain as day so not to divert the eye away from where the action is really happening......on the display !

Is it because of EASL or are datasheets and manuals difficult for you to understand ?

Like I mentioned before you could really benefit from getting a modern DSO to learn what they really can do instead of some decades old blinkered incorrect opinion.

(EASL)?

English as second language......what other excuse is there for such grossly wrong thinking ?

We each have a responsibility to those that come after to provide the best correct and latest information not some ramblings from last century.

This is our responsibility ^^^ to provide accurate and correct facts.

Take the topic of this thread and ask whom manufacturers a CRT TV or monitor today and then ask who in these energy challenged times would want to use one ?

At one time walked then we used horses to pull carts then made cars and then planes....it's called progress and difficult for some to fathom or accept.  ::)

if EASL is a problem, we have TESL very well accepted in academic level. ;) the usual reasons imho is lack of googling, or hard to get rid old habit (i also have this syndrome in computer programming and CAD notions)

but people can still argue horses dont need gas, not poluting environment, no need dedicated parking lot or lane and other sane reasons. at least i saw in movie, some police dept or enforcement still use horses in 1st world.. so people can use the analogy to stick with CRO, but for the above said unreasonable reason (fallacy). ymmv.

--- Quote from: tggzzz on December 15, 2022, 06:39:05 pm ---Unfortunately I have heard too many people saying they want a digitial scope solely because of the auto-setup button. On further questioning, they actively don't want to learn what's in a scope, nor its pitfalls and traps, nor how to get the best from it.

Micsigs have a mode where they continuously adjust the horizontal/vertical scale to track the input signal - no need to press a button!  :)

It is hard to think of a more annoying feature!

Depends on the implementation. Watch this video at the 12:40 mark before deciding:



He leaves it on for most of the video. Just watch...

some people make fun of Auto feature in DSO, but at the same time the same person wants everythings "managed" automatically from behind when discussing in Programming Language section...  On further questioning, they actively don't want to learn what's in a programming language, nor its pitfalls and traps, nor how to get the best from it... ;D btw, i'm "manual car" type of guy, so i dont use Auto feature very much, the same in (C/C++) programming language. cheers.

Unfortunately this won't work. The presence of a CRT monitor does not guarantee that the oscilloscope is analog. HP/Agilent produced digital oscilloscopes with CRT monitors.
