CT-WTFS9000 Grandmaster Clock receives GPS, BD satellite signal as well as various external time source. Built-in Rubidium clock and supporting multi-format outputs make it a super high precision, powerful and scalable grandmaster clock which meets the timing requirements of complex systems, and widely used in areas like energy, power, telecommunications, military and transportation etc. It is the primary clock of the CT-WTFS9000 Wide Area Time & Frequency Synchronization System. Functions : Stratum 1 operation via GPS and/or BD satellite Support multi-format inputs: PTP, IRIG-B, BITS,10MHz Support multi-format outputs: NTP, PTP, IRIG-B, Pulse, Serial, BITS, 10MHz 1x 10/100 Base-T Ethernet interface for management Internal precision time-keeping via Rubidium clock Support automatic selection of valid time source Support IEC61850, IEC60870-5-104 standard Fault alarm functions for time source, board cards, power supply and so on. Time delay compensation mechanism, compensation range: 20ns~500ms Time continuity judgment mechanism to avoid output time discontinuity Rigorous frequency calibration algorithm, to obtain high stable frequency holdover accuracy Features Flexible module card design, easy for outputs configuration 2 x internal frequency source are configurable, to ensure the internal time reliability and security Support duplex, hot standby, cold standby configuration LCD display with man-machine interaction brings a simple operation Adapt to the strong electromagnetic interference environments Redundant dual power supplies 19’’ / 4U rack mount Specifications: Time Reference BD B1, GPS L1, BD & GPS Inputs PTP, IRIG-B, BITS, 10MHz Outputs IRIG-B TTL?RS422/RS485?RS232?Fiber?idle contact Pulse(1PPS/1PPM/1PPH) TTL?RS422/RS485?RS232?Fiber?idle contact Serial (TOD) RS232 NTP/SNTP RJ45 PTP over Ethernet RJ45 PTP over E1 BNC 10MHz BNC BITS BNC Time Performance Time Accuracy to UTC =100ns(RMS) Holdover Accuracy =500ns/24hr ( After 24 hours locked) Frequency Accuracy =1E-12/day (After 24 hours tamed) Frequency Stability
