Well, go and look in the HP5335A service manual and decide for yourself.
Naturally, there is the issue about input/trigger design, but that is a common
I would not do this stuff with a clock lower than 50 MHz today. It is easy
enought to acomplish it. 10 MHz is nice and dandy for reference, but I would
use a low-jitter VCXO and lock it to the 10 MHz and then use that clock for
