The XR5000 equipment is small and lightweight desktop time source, able to provide a high stability reference over an Ethernet TCP/IP network. The XR5000 timeserver uses NTP (Network Time Protocol) protocol to synchronise any computer on the network. It holds two outputs connectors :
- Standard RJ45 for network link.
- SubD 9 pins dedicated to RS232 link witch sent a time frame every second (1Hz). Any PC using a specific software driver in order to synchronise his internal clock could read this frame.
A choice of two independent time sources is available for time input :
- IRIGB input
- A GPS module able to provide both UT and high stability 1 PPS signal.
GPS
The GPS module receiver 12 channels able to acquire 12 satellites and to deliver a very high precision 1 PPS.

- NTP Server:
The XR5001 server is NTP-Primary server type with the following functions :
- Level 1 server, compliant with NTP protocol release 3.0.
- Mode: server (question/answer).
The client’s computers could be synchronised with a precision of 1 to 10 ms, depending on network load. Equipment and server status information’s are available through the SNMP (MIB) protocol. A NTP client must be installed on every client computer for his synchronisation with the server. Power supply is an external block sector.

- Irig-B:
The IRIGB input uses the standard 1 KHz amplitude modulated signal compliant with IRIGB STANDARDS 200-98.

- Remote control:
The equipment remote control function uses a dedicated RS232 link. Also, the TELNET utility software allows the same operations though the network.
