GMR5000
The GMR5000 is high-precision, multi-function master clocks that can act as an NTP server, PTP grandmaster, time code generator or frequency reference.
The GMR5000 is a master clock that can reference a variety of timing sources and provide a range of outputs including NTP, PTP, SMPTE, and IRIG-B. The internal modular design allows the unit to be factory-configured per the user’s requirements. The base model includes both NTP server and client functionality compatible with IPv4/IPv6 networks and offers AES 256 SSH encryption for secure communications. Optionally, the device can act as a IEEE1588v2 PTP grandmaster or slave clock, time code generator, NENA time server, frequency generator and more. Optionally, an OCXO or Rubidium oscillator enhances holdover stability to minimize timing drift.
