The GMR6000 master clock is a modern and versatile time server and frequency generator. The device can reference and synchronize to a variety of input sources and provides a local physical realization of time for systems to utilize. With built in power redundancy and intelligent switching and monitoring, the GMR6000 meets or exceeds contemporary system requirements for ensuring availability, accuracy, and traceability of time and frequency signals for mission-critical applications.
The GMR6000 incorporates key features designed to plug gaps in existing competitive options to enable uninterrupted synchronization for downstream devices. The inclusion of a variety of device-level mixes of dual-power options (AC/AC, AC/DC, DC/DC), the available multiple isolated ethernet interfaces, and upcoming intelligent Auto-Changeover (ACO) accessory all allow multiple layers of fail-safe options for systems to sustain reliable time and frequency utilization.
This model comes with a preconfigured GMR6000-GMR-FREQUENCY OUTPUTS license which enables Programmable Reference Frequency Output via Masterports, BNC Cntr.
