The AccuSync-R is a redundant GPS time & frequency system packaged into a 1U high rack mount chassis. The unit is optimized for synchronizing multiple sites to UTC time of day.
What makes this AccuSync-R unique is that it contains two time and frequency modules that contain the GPS receivers, oscillators, as well as a CPU. Each module is hot swappable and includes front panel status LED’s forpower, GPS lock, holdover and fault status. The oscillator on each module is a single oven OCXO which is disciplined by a FEI-Zyfer proprietary algorithm that has been developed over the last 6 years using our experience in synchronizing CDMA base stations. The AccuSync-R offers built-in distribution of six
frequency outputs as well as four 1/6 PPS outputs and one 1 PPS output. The unit can be configured or
remotely managed using a rear mounted RS-232 port. Operation of the AccuSync-R is completely automatic
and self-calibrating. No user programming isrequired for the system to become operational. Controlling and performance monitoring are provided via an RS-232 interface.
