NTS-4000 OCXO
NTP, PTPv2/IEEE1588, IRIG-B, 1PPS, 10MHz
10GbE or 100/10Mbps, also 1GbE w/
hardware time-stamping (FPGA)*
NTS-4000 is a PRTC-A GrandMaster PTP/IEEE1588 and NTP Network Time Server. Built-in HQ OCXO oscillator guarantees precision time for period of missing GNSS satellite signals. Max. configuration includes 4x LAN interfaces. Std configuration includes only 2x 10o/10Mbps LAN1/LAN2. The LAN2 can be upgraded to 10GbE supporting software time-stamping. Optional EXPANDER card supports another 2x 1GbE LAN3/LAN4 with hardware time stamping. NTS-4000 supports 2x redundant GNSS receiver (RJ45 inputs ANT1 & ANT2) and redundant* power supplies. The sync I/O are: 1PPS, 10MHz, IRIG-B, ToD(RS232),
