Hi Hal, My aim is to run a stable time standard to analyse the long term performance of clocks. Part of this project is to set up a power support system so that logging is never interrupted. Now the LPRO draws less power at lower supply voltage and higher operating temperature and decreasing the power demand was important. Now OCXO systems are greatly improved by double ovening them so it seems hard to believe that the LPRO will not improve with accurate control of temperature. My project is not complete and my planned method of measuring drift is with a digital oscilloscope comparing the phase of PPS from GPS stabilised systems to the divided 10MHz from the LPRO over a period of days, weeks, months or years. cheers, Neville Michie
