Sorry for going off subject, but I couldn't help the Members Only reference.I used to use an old CRT scope as a monitor for grins for a long time.
Battlezone.... yes, in my arcade days.
I still have a members only jacket, too
DSOs have the ability to record a waveform and display it later. That's something an old CRT scope (unless it's one of the old CRT based DSOs) does not have.
You can also extract that data and analyse it later.
That's fairly important if you want to analyse the minutiae of a signal.
There are things you can see on a DSO (depending on memory depth) that you can't on a old scope. Triggering and advanced measurement as well.
Beware those using a video by a prominent engineer to advance a sales pitch, which is quite sad and desperate.
Fiddling with XY mode can be a lot of fun.
I still do it.
Back when I was in my mid-to-late twenties (late 80s and early 90s) I was spending lots of time around Goodfellas that actually worked for for Al Capone when they were kids.
It was unacceptable to dress like I would've wanted too while hanging out with these fellas. I was into bands like Nirvana, Pearl Jam, Alice in Chains excetera excetera excetera, and would have preferred to dress as I would've liked to.
Unfortunately it was unacceptable to do so while hanging out with what we referred to as the mustache Pete's. A mustache Pete was and still is used to refer to a old time mafioso. Although most of those guys are long gone the frase is still used (rarely.)
We spent so much time around them we'd inevitably go clothes shopping with them. We couldn't help but pick up the style of the mustache Pete's. Unfortunately for me and many of my friends Members Only was almost a clothing prerequisite. Heres the proof. Members only jacket, and shirt. Lol.... P.s. having to wear members only at such a young age has left me traumatized. At the ripe old age of 54 I now wear Ralph Lauren skinny jeans/ sweats, Enemy of the State, mafioso, and some throwback Hilfiger t-shirts. I own and wear nothing but Timberlands (not the kind one where's while doing construction work.) That's the type of clothing I should have worn then.
