Re: DIY TD Pulser
Not sure what exactly you have two of... 😊
I've posted some test results from two samples of the build I did following the notes from Sergey Kubushyn. The test was conducted over the noon hour on an 8 GHz digital Tektronix scope at work - didn't catch the exact model number.
I posted captures of the rise time photos under "DIY TD Pulser" in the Photos section. Got 159 pS on the first build. Was a little more careful with the output construction on the second and got down to 119 pS with it.

I have two of them. One has a bad TD, the other works, but
is easily 10 times slower than the spec's say it should be.
I had heard that when tektronix made them they had no real
way of measuring the pulse risetime, so they guessed.
