Time-nuts!
With care I can measure GPS jitter on a RasPi to a bit over 300 nano sec
resolution. That is the smallest increment of the RasPi 3B clock with
a 64-bit kernel. That is clearly not time-nuts accuracy.
What would you guys suggest as the cheapest way to see jitter down to
around 1 nano second?
I'm thinking maybe something like a rubidium standard (FE-5680A) and
a TICC-TAPR? But that would put me out around $400.
The picPET does not look accurate enough. Maybe a clever way to use it
for more accuracy? Is there a picPET like thing cheaper than the
TICC-TAPR?
Ideas?
