Ct-Wtfs9000 Grandmaster Clock

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 ocxo 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-bTtl?rs422/rs485?rs232?fiber?idle contact Pulse(1pps/1ppm/1pph):Ttl?rs422/rs485?rs232?fiber?idle contact Serial (tod)Rs232 Ntp/sntpRj45 Ptp over ethernetRj45 Ptp over e1Bnc 10mhzBnc BitsBnc Time performance: Time accuracy to utc=100ns(rms) Holdover accuracy=1µs/hr (after 24 hours locked) Frequency accuracy=1e-12/day (after 24 hours tamed) Frequency stability

Ct-ddt200 series digital clocks (ntp/irig-b/serial) Ct-ddt200 series digital clock receives time signal from a master clock, supports ntp?irig-b and serial input, provides highly visible time displaying in public places like hospital, school, train station, airport and bank etc. Key features Multiple time signal inputs: ntp / irig-b / serial Time synchronization accuracy = 10ms High internal holdover accuracy when loss of time signal High-brightness digital tube with bright and uniform color Adjustable of light brightness, to satisfy different situation demands Support ceiling suspending, wall hanging and embedded installation Support yy:mm:dd, hh:mm:ss, week / temperature / humidity display Display content, single or double screen, light color, size are all customizable

The ct-dz600a satellite synchronous clock (which is also a network time server) is developed with modular hardware design in a 1u chassis. It receives gps or bd satellite time source, supports multi-format outputs (ntp, sntp, irig-b, pulse, serial ), brings you a highly accurate, powerful and scalable time synchronization server widely used in telecom networks, communications, railway systems as well as power industry etc. Functions Stratum 1 operation via gps or bd satellite Internal precision time-keeping via ocxo 3 optional module slots allow multi-format outputs (ntp/sntp, irig-b, pulse, serial) Time delay compensation mechanism, compensation range: 20ns~500ms 1x 10/100m ethernet interface for management Secure web-based management Snmp simple network management supported Features Flexible modular design, easy for outputs configuration Nanosecond time accuracy to utc Excellent internal holdover performance when loss of time source High-precision time synchronization satisfies enterprise class users 3 years limited warranty Certified ce, rohs Specifications Time reference:gps l1 ?bd b1?bd &gps?glonass(optional)?galileo(optional) OutputsNtp/sntpNetwork interface10/100m ethernet port, rj45 Network time protocols:Rfc-1059(ntp v1)rfc-1119(ntp v2)rfc-1305(ntp v3)rfc-5905(ntp v4)rfc-2030(sntp) Ntp time sync accuracy:1ms~100ms(rely on the network environment) Ntp access ability: 1000 requests per second Time performance Time accuracy to utc=100 ns (rms) Holdover accuracy=40µs (after 1 hour) ; =90µs (after 2 hours) (lose of gps after 30mins locked.)
