Welcome to IWETHEY!

New Well done.
When I was in college, I was taught that standard RG-58/U 50 ohm coax delay was "2/3 of a foot per nanosecond". It stuck with me.

(The signal speed in a real cable is less than c.)

Cheers,
Scott.

Stage scenery:

A) Tektronix Model 284 TD/tunnel-diode fast-pulser, claimed 70 PICO-second tr aka Rise-time.
B) Tek 7854 nom. 400 MHz scope (first Successful design w/BOTH fast single-shot analogue and with digital storage, analysis etc.)
(Mine specs out at ~500 MHz. Fastest time-base has a "200 Psec/DIV" position.

One Looks: at the display (..and can factor-in the 70 pSec source) displayed at 550 pSec scope tr
One Sees! that Half-a-Nanosec step-change, occurring over a couple cm. of the 10-cm. sweep length.


Por moi then, it's just a lot more stirring of the analytical-Soul on Visual -vs- that piece of wire-in-hand.
'Course the equipment cost is not insignificant, compared with "zero".. .... details, details.

New You made me think of "my" Tektronix 545B with a dual trace module.
Nothing as good like what you're talking about that, but in the early sixties it was the cat's meow! It came with a roll of silver solder.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

New Yeah.. vas dere, Charlie
When I thought to do some Audio flogging (so's to get my Own better gear) I got a demo==call-it-New 503,
a paltry 500 KHz (!) BW, but with the display, triggering etc. of Tek built-in.

Lab rife with 545s (maybe -Bs also, but not in Our bailiwick.) So I arabesqued the vacuum-tube era ..never having seen, turned knobs of the 547, as progress -->Happened (well, at Tek anyway.)
(Even at Lab when first I arrived, the Electron Synchrotron had execrable == pre-Tek scopes) I recall Our first shiny 545 and Oohh ing over a Real "time base" (not yer Gramma's Theremin-with-pots/potentiometers.)

I wonder if you Can become conversant with electronics ... via simulators as so-fit-the Game-mentality now purporting to render obsolescent: EXPERIMENT!
Believe that baby already went out with other shades of bath-water
