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 :D

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.)

A candidate for “lowest price” (~$150 scope with AWG).
50MHz from the built-in AWG of the DSO2000.
AWF with coax and 50Ω LR.
