The GMR5000 is replacing the MCR5000. Upgrade your system today.

MCR5000 Master Clock

The MCR5000 Master Clock Reference system is a 1RU rack mount, precision time and frequency device. It’s larger than the MCR1000 and can handle more modules. One compact unit can reference and output NTP and Time Code. It provides a 10-MHz sine wave locked to GPS satellites with a high stability crystal oscillator backup. With specifications equal to or better than almost any other similar product, the MCR 5000 is available in multiple configurations to fit almost any need and is much less expensive than comparable products.
