One point made in it is the use of scope probes. I think compensating a scope probe can partially reduce the effect of scope rise-time .

No, it can only reduce the effect of a poorly compensated scope probe. It can't help the risetime of the scope itself (without causing other, even more undesirable, problems).

Probe compensation is in the microseconds time domain, and rise times are down in the nanoseconds.

It's only a newsgroup. It doesn't matter.

Context does matter, that is, if you want others to understand you.

Then why are you wasting your precious time here? John Fields.
