Grand Master Clock

Internal Time Base
The Quality of its oscillator allows to provide stable time signal even in holdover
mode.
Rubidium (40W power consumption) :
• Frequency stability (Allan Deviation) up to 3.10-12
• Maximum frequency change over operating temp range from -20°C to +60°C:
1.10-10
• Ageing : 5.10-11
• Time drift (without synchronization over 180 days : < 10 msec)
Key Features
• Compensation of input delay due to transmission distance and security
threshold setting. Time Base and algorithm ensuring output accuracy up to
100ns when synchronized to GNSS.
• PPS and 10 Mhz output via BNC connectors.
• Alarm management via SNMP TRAP for alarms and events.
• Manual or automatic adjustment for transmission delay.
• Event recording system.
• 100% operational within 3 minutes (with min. 6 satellites available).
• Configuration modifiable via SNMP.
• Internal Temperature monitoring (°C).
• 1 NTPv4 default output on the management RJ45 port.
Network Protocols
