Multi-functional Master Clocks
MCR1000
1.1
The MCR1000 Master Clock Reference system is a compact, precision
time and frequency device.
One unit can reference and output NTP, time code, and 10 MHz sine
wave all locked to the Atomic Clocks in the GPS satellites with a high
stability crystal oscillator backup in the case that GPS signal is lost.
With specifications that are equal or better than almost any other
similar product the MCR is up to 60% less expensive than its
competition.
The MCR1000 is available in multiple
configurations to fit almost any need
with configurable modules.
Rack mountable with
