How accurate is the clock in a scope?  Do the high end scopes have an 
external clock input?

I remember playing with a scope many years ago.  Trigger on a PPS from a GPS, 
look at the next PPS.  It should be 1 second later.  I think the scope I was 
using was off by 6 PPM.

I'd expect that there would be a crossover.  For short times, the scope would 
be better.  For long times, the better crystal (or external input) in the 
5335 would take over.

These are my opinions.  I hate spam.
