Master Clocks

   

A master clock can be known as a reference clock, time standard, network clock, authoritative time source, sync clock, or atomic clock.

But the function is the same: to keep timing systems and secondary clocks (slave clocks) running consistently to improve performance. A Spectracom master clock offers the additional advantage of accuracy and traceability to national and international standards by using GPS and other atomic time sources. NetClock® and Epsilon Clock™ master clocks have been optimized for the specific requirements of many applications and industries including vital communications and command centers, such as 9-1-1 and other public safety answering points (PSAP), aerospace and defense, and telecommunications and broadcasting.
