It amazes me that I can see the the delay in a short piece of wire.
All of the sudden I see a value in my new 300 Mhz scope. Lower time base.

OFF TOPIC, SLIGHTLY:

With a wideband scope, you see many interesting things, including some that
might surprise you. Years ago, while looking at some short pulses (to
evaluate the response of a new amplifier), I saw unexpected "steps" in the
traces. I was using BNC T-connectors and my test setup had accidentally
duplicated a TDR function. The impedance change reflections were plainly
evident in a few feet of 50-ohm coax. (I've since seen plans for a
home-brew TDR similar to my accident. :-)

I enjoy amazement, too.
