Why? Risetime is stated in the datasheet

It's not like you don't trust the datasheet. The journey is the destination - you just need to have measured it yourself once (and understand what you are doing, and why you do it the way you do it) ;) Consider it an exercise.

Precisely!

It is about testing the person's understanding of the dcooe, how to use it, measurement techniques and pitfalls.

I applaud the OP for doing it, think they will learn a lot, and will emerge a better engineer :)

Not to mention that whenever you get a new toy you just want to see what it can do.

That presumes you know how to use it and find its limits, not everyone does.
There's a good reason why I shelled out on a RF gen and Leo Bodnar 30ps pulser.

Well, you don't have to go that far.  Especially if you want to employ a little math.

For testing a rise time near 3.5ns, 500ps would be fine and introduce an error of just over 1% without doing any math.

You would introduce much more error by hooking everything up incorrectly.
