OVERVIEW Masterclock's Master Clock Reference system is a compact, precision time and frequency generator for a wide range of applications in the commercial, industrial, military and laboratory environment. One compact unit can generate and read NTP, time code, high stability oscillator, and 10 MHz sinewave all locked to the Atomic Clocks in the GPS satellites. With specifications that are equal or better than almost any other similar product the MCR is up to 60% less expensive than competitive units. The MCR 1000 is available in multiple configurations to fit almost any need with configurable plug-in modules. Give our sales department a call and discover how easy it is to configure a system to fit your requirements.
