[time-nuts] TICC reference source

[Taka Kamiya]

Thank you!  This is a great manual for time interval measurement.  I'll go with 10811.

 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.

I am building a TICC-IN-A-BOX.  Basically TICC + TADD-2 mini + reference oscillator.
Initially, I was going to use HP11811-6011 but I am also considering PRS10.  (I already own both)  While I believe 11811 is sufficient, PRS10 can be kept off and reaches usable state (physics lock) faster, while 11811 has to be kept on or otherwise usable stability will be few hours.

I do have a house clock but since it can be a subject of measurement, I want my TICC-IN-A-BOX to have an independent clock.
Am I thinking correctly?
