Problem with you is that, unlike Wuerstchenhund and Someone, you don't seem to know much about other scopes but keep on trumpeting how great Tektronix is.
You stated previously that 15 years old Agilent scope is still being sold. And you did so many such gafes, never admitting you were wrong.
To be able to compare two things you need to know both well..
And Wuerstchenhund arguments with Someone are not really connected with you or your posts, but are continuance of history between them, that originally resulted in Wuerstchenhund being banned here.
Let's summarise facts that are certain:
- Tektronix made some of the greatest analog scopes. They are legend because of that. As kids we all dreamed about them..
- When scopes started going digital, things got fuzzy. Ever manufacturer had their vision how digital scope should look like and all of them made them different and all of them did some things worng and some things right
- With digital scopes being different animals, users and manufacturers started making different workflows for old analog ways of doing things. Some new practices deliberately wanted to keep old analog workflow on digital scope, some deliberately used completely new way of doing things, taking advantage of fact that digital scope could (and sometimes couldn't) do things old analog couldn't (or could).
- With years, because of all that difference in opinions, and user requirements, practice and experience, in some points manufacturers largely diverged in a way how they make scopes, and in some points they all started to do things same way as others because it works and user wants it. Which lead to fact that, sometimes, some functions that were supposed to be the same, worked differently on different platforms, with all the consequences of that to the user.
- In meantime, lots of new players came to arena, and now low cost market is ruled by B brands (with all the good and bad coming with it)
- A brands (and especially Tektronix, because of owner structure) are not what they used to be. Sort of. Stuff is still pretty good quality, some of the standard support for some of the product clases is not as it used to be. Generally, to get great support you have to pay extra. In the olden days it wasn't so, but then stuff was really expensive and manufacturers could afford it. Keysight seems to be best in that regard.
- Of all the A-brands, Tektronix has worst price/performance/feature/benefit ratio. That doesn't mean their stuff is crap. It means it's overpriced for what it is .
- TBS2000B seems like a nice entry level scope. It defintely is not crap quality stuff. But as Wuerstchenhund nicely said "Outside education, there is little reason to buy a TBS2000 scope over anything else. The quality isn't better (and even Rigol and Siglent make pretty robust kit these days), Tek support is somewhere between poor and horrible, and the warranty is mostly the same around the various manufacturers.".
That scope has literaly
nothing on it. It has functionality of TDS200 series with more memory, larger sample rate, few more measurements and nice big colour screen. There is no even basic decoding, nothing. Literally any cheapest scope from Rigol, Siglent, Keysight, R&S, GW-Instek, even OWON, would allow you to do more things and be more useful to user. It is a "digitally emulated analog scope" in concept. That ship has sailed years ago. If you really want analog scope get real one. It's great fun.
