Timing reference systems

IPSES and Eurolabs produce and sell systems for timing and frequency generation, conceived to answer to the best industrial needs.

All systems generate an exact frequency of 10MHz and a synchronization pulse every second (PPS) and are based both on precise OCXO, DOCXO or Rubidium oscillators. The accuracy of the frequency of 10MHz is a least 0,000000000002 (for the version equipped with OCXO oscillator), while the precision of the synchronization pulse is less than 100ns.

These systems, in addition to provide directly the synchronization signals, can also operate independently as NTP server and be used as synchronization server for PCs and other systems linked to a Ethernet network.

All systems are also able to maintain very low the drift of frequency in the case the synchronization time reference is lost: the maximum error rate of 10 MHz frequency is less than 0.0000000003 every 24 hours of holdover in the version with OCXO oscillator, wand less than 0.000000000003 for version equipped with Rubidium oscillator.

The time reference for the synchronization of the system can be given by any stable and accurate over time PPS, generated by another system, or can be automatically detected by using a integrate GPS receiver.

All systems are carefully calibrated and tested before being sold.

Available models

TimeKeeper: Synchronization and maintenance of the reference time board. It connects directly to a PPS and is able to maintain the reference time for several hours even in the absence of input synchronization.

GPSTime: Detection, synchronization and maintenance of time board equipped with GPS receiver. It is enough to connect the card to a GPS antenna so to perfectly synchronize it and to maintain the reference time for several hours even in the absence of GPS signals.

GPS-NTP: Detection, synchronization and maintenance of time board equipped with GPS receiver with built-in NTP server. Simply connecting the card to a GPS antenna, the system will synchronize and run like a very precise and and standard NTP server.
