Mine arrived today. Alas, it uses a USB B connector instead of a more
common USB mini or micro; I gotta get a cable.
Mine has the comparator IC marked only, "AJK BAA." Yes, this is an
Analog Devices ADCMP572 or ADCMP573 Ultrafast SiGe comparator. I'm not
sure which output configuration is use

I built one, and later saw a simpler one. Very fast, very simple. I think my
total cost was a few cents.
Google TDR DIY pulser. One from an old magazine (Jim Williams) looks pretty
good, using collector breakdown of a 2N2369. The one I made used one IC and a
few resistors.

I looked at the picture and I can see now that the sma is the pulse and the
BNC is the output trigger. Pretty interesting for the cost.
I then did a search on google for fast pulse generation and a analog
devices solution came up that delivers 50ps and actually shorter. I doubt
its one and the same

When I was working with microwave semis it was either a tunnel diode or
a Step Recovery Diode.

I expected it to be a variant of the Jim Williams avalanche pulse
generator, but one of the photos shows a part marked AJK AAA that appears
to be the active component.

There has been discussion recently about generating fast rise/fall time
pulses by various means. Here is a link to a Leo Bodnar device that will
provide <40 ps rise/fall time, 50% duty cycle, 10 MHz pulses:
