Technical Notes and Briefs: EpsilTime™ Synchronization Algorithm Spectracom time and frequency synchronization management algorithms, like EpsilTime™ used in models EC20S and EC22S, uses smart predictive technology to mitigate the effects of inherent GPS and oscillator noise, improves accuracy if GPS is lost(holdover), and corrects drift in the 10 MHz and 1PPS outputs simultaneously. That means there are always 10 million frequency cycles between every one pulse-per-second. pdf - 122 KB
