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 have used this technique for many years, but never for more than the 3 day default of LH. For all of you LH gurus out there, is there a way to collect long-term raw data that can be processed by TimeLab or Stable32? Thanks in advance for any help. Regards, Skip Withrow

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 file(s) that are convertible to work with just about anything. You can feed it into TimeLab, Stable 32, Excel, ….. whatever … Bob > On Sep 21, 2020, at 1:24 PM, Skip Withrow <skip.withrow@gmail.com> wrote: > > Hello Time-Nuts, > I am interested in making some long-term (weeks/months) oscillator > measurements.
