page 48 here has some notes on time-base error: http://leapsecond.com/hpan/an200-3.pdf
for time-interval measurement the number of digits matter. if you keep time-intervals 'small', say 123.45 ns (probably can't resolve much below 10ps anyway with a TICC) then a time-base with only about 5-6 digits of stability&accuracy is sufficient - even if you are measuring two good H-masers against each other. The OCXO may have better short-term stability compared to the Rb. Anders On Fri, Jun 14, 2019 at 5:01 AM Taka Kamiya via time-nuts < [email protected]> wrote: > I am building a TICC-IN-A-BOX.
