          DESCRIPTION1558099262372655.png

                     Sync-tech’s frequency standard (BD 1024) delivers exceptional frequency stability. Thanks to a stability specification for 30-day averaging time, the clock can keep extremely predictable time and phase for long periods. Combined with a GPS timing receiver the frequency standard can produce a highly robust, inexpensive, and redundant frequency and time system.




          Benefits

          • Maintains exceptional accuracy and stability even in unstable environments—unsurpassed stability in the lab or field

          • Accuracy ±1.0 x 10–12 for standard performance; ±5.0 x 10–13 for high performance

          • Stability ≤1.2 x 10–11 for standard performance; ≤5.0 x 10–12 for high performance (for 1 second averaging time)

          • Environmental stability ±1.0 x 10–13 for standard performance; ±8.0 x 10–14 for high performance (frequency change for any combination of environmental conditions)

          • Long-term stability ≤5.0 x 10–14 for standard performance; ≤1.0 x 10–14 for high performance (for 5-day averaging time)

          • Proven reliability with an average mean time between failures (MTBF) of greater than 160,000 hours
