GMR1000 Master Clock


Overview

1U Rackmount Multifunctional Master Clock

The GMR1000 is a compact master clock that can reference a variety of timing sources and provide a range of outputs including NTP, IEEE1588 PTP, IRIG-B, SMPTE, 10Mhz, 1PPS and more.  

The base model includes both NTP server and client functionality compatible with IPv4/IPv6 networks and offers AES 256 Secure-Socket-Host SSH encryption for secure communications.

The device can act as a IEEE1588v2 PTP grandmaster or slave clock, time code generator, NENA time server, frequency generator and more.
