Volker,
That's a great question and I'm afraid I don't have a good answer
for you. If pressed, I would estimate less than 100ps.
The error of this measurement contributes to the error in our
final measurement which has many components. I haven't worked out an
error budget for each contributor. Our goal is a final error of less than
10ns. But a few contributors are already expected to be around 1ns, so
this error really needs to be less than 1ns, preferably less than 100ps.
Cheers,
Paul

I agree. Since Paul want's to use an SR620 I presume he needs precision.
Otherwise almost any TIC with a fairly stable osc would do, for example
one with a battery backup. So I further presume that he needs nearly the
full accuracy / stability. But that's just speculation, surely Paul can
answere this question?
