Time Server PTP/NTP

Rack 19″ (1U)

NTS-3000

NTP,  PTP/IEEE1588, 1PPS-input

10GbE*/100/10Mbps LAN1-LAN2

1GbE* w/ HW-stamping LAN3-4

NTS-3000 is a GrandMaster PTP/IEEE1588 and NTP Network Time Server. Optionally can be equipped with HQ OCXO.  The oscillator guarantees precision time for period of missing GNSS satellite signals. Max. configuration includes 4x  LAN interfaces. Std configuration includes only 2x 100/10Mbps LAN1-2.

 

The LAN2 can be upgraded* to 10GbE* supporting software time-stamping.

 

Optional EXPANDER* card supports another 2x 1GbE LAN3-4 with FPGA hardware time-stamping. NTS-3000 supports 2x redundant GNSS receiver (RJ45 inputs ANT1 & ANT2) and redundant* power supplies. The sync I/O are: 1PPS-input (BNC)
