Re: [time-nuts] LH and long-term oscillator measurement

Hi An alternative: Take the pps out of a ( or maybe several) GPS modules. Divide your oscillator to (about) 1 pps. Feed them into a counter(s) of some sort (TICC or 53xxx or whatever …) Log the data to a file with any serial program you might pick. = At this point you have a data

[time-nuts] LH and long-term oscillator measurement

Hello Time-Nuts, I am interested in making some long-term (weeks/months) oscillator measurements. I figure GPS is the best long-term reference that I have, so would like to use a Thunderbolt with the oscillator pulled and the DUT substituted, and running Lady Heather (with discipline off). I
