Gave us:


It's a hell of a lot easier to have a scope that puts out jpegs with
a single button press.

For someone that brags about having so many millions trickling
through your company, one would think you could afford a modern scope.

Bwuahahahaha!

It's a Tektronix 11801A 20 GHz sampling scope. I got this one on ebay.
The current version, with a couple of sampling heads, would cost about
$70K. The 11801A has a magnetic-deflection, vertical raster scan color
CRT, which is very difficult to photograph. The Cybershot, even on a
2-second exposure, has all sorts of goofy scan artifacts. The
distortion is real, namely on the screen itself, not a result of the
photography.

The snap I posted is the rising edge of an output pulse from our first
all-CMOS digital delay generator...

We had the formal release party for rev C this afternoon. The
trigger-to-output path passes through 10 distinct CMOS stages and
we've managed to get the prop delay down to 20 ns and the jitter below
20 ps.

Congratulations. It sounds like another winner, John.
