 Product Features

  • The device adopts plug-in structure, configuring boards according to user requirements
  • All boards realize redundant hot backup, no jump in time and frequency during switching

  • Can receive BeiDou (B1/B3), GPS, GLONASS satellite signals to calibrate the local time

  • Can receive external 1PPS+TOD, IRIG-B(DC), IRIG-B(AC), PTP, etc. for time reference

  • Optional rubidium clock, crystal, external 10MHz as local frequency source

  • Optional output 1PPS+TOD, IRIG-B(DC), IRIG-B(AC), NTP, PTP, PTPoverE1, 10MHz, E1/T1 and other time and frequency signals

  • The system can monitor the status of the equipment through the network port or serial port when it is in use

  • Equipment can choose 3U/4U chassis
