Most interesting reading.  When the founder/owner of Pico Secod Puls Labs retired,
he sold the farm to Tek.
First thing that TEK did was to axe the app notes from the PSPL web site.
Probably too many independent comparisons.

My pulse generator from Leo Bodnar arrived yesterday, so I would like to contribute with my slow-but-I-am-loving-it EDUX1052A. (...)

I wonder where that aberration came from; it is much greater than I would expect considering the much faster settling time of the pulse generator compared to a 60 MHz oscilloscope. My guess is that the oscilloscope does *not* have a Gaussian or single pole response.

Yes, I did not expect to see this kind of overshoot on a scope with 50MHz bandwidth. For reference, this is the same pulser on the EXR104 I am using at work. This time without inline terminator in native 50R mode.

Now you get to ask yourself why there is preshoot.

Nice, what I would like to see the real time behavior, as 20..80% or 10..90% rise time changes over time

On a LeCroy easy to graph over time as rise f(t).

Thanks for the suggestion  We'll add the ability to graph any measurement vs. time to the software. (Fastest update rate would be 1 datapoint per sweep.)
