Choosing between entry-level 12-bit DSOs

Yeah well you'd be surprised how many instruments are in our 200kg shipments these days @~1.25m3 I can comfortably get all in a 5 door SUV.

A small portion of a dozen or so are going to EMEX for next week's show, along with tables, big screen and a mini PC and assorted other bits and bobs.

Won't include a 10.6kg SDS7000A DSO unfortunately.  :(

Precisely. Not a difficult concept, really!

Let's take as an example excellent Tek 485. It has 8mm/div graticule 8x10 grid.
Which makes for an whooping 64x80 mm of active screen size.

In attachment (roughly) sized overlay of 485 screen over SDS800xHD (a tiny 2.5kg scope with 7" screen), and over SDS1000/2000/3000xHD with 10" screen.

Not to mention that on a digital scope you NEED to have data on screen. What is your V/div for CH1? Probe att? Timebase and time delay ?...
On CRT scope you had HUGE front panel with MINISCULE screen and for settings you could look at physical buttons/knobs.
On digital scope you need to have that data on screen.
And since the screen is so much bigger you lose nothing compared to old analog scope.

Some people think feel smart for being able to do the things the hard way.
Some people kinda like to have lots of additional information right there on the screen in the plain sight.
Everybody have their own definition of fun. Or what is a waste of time.

CRT scopes do still have some advantages in certain niches (like scope art) but claiming that they are better because they have small stupid screens with no data whatsoever (except unexplained squigle and a graticule) and claiming that is advantage is very questionable statement......

You do understand the distinction between size and resolution - don't you?

Apple understood the distinction, and ensured the original Macintosh embodied the distinction quite clearly: smaller than a contemporary IBM PC screen, but looked better.

Then, of course, there are the more nebulous concepts of clarity, readability, and usability.

I do understand the difference.

I also understand when someone violently changes the subject because they are proven wrong, and God forbid they admit it..
