MCR1000 GPS Master Clock

The MCR1000 Master Clock Reference System is a compact, precision time and frequency device. One unit can reference and output NTP, time code and a 10 MHz sine wave all locked to the atomic clocks in GPS satellites. A high-stability crystal oscillator (OCXO) acts as an internal source of accurate time in case GPS signal is ever lost. With specs equal or better than almost any other similar product, the MCR1000 is up to 60% less expensive than its competition and available in multiple configurations to fit almost any need.
