FEI Zyfer GSync II Model 402
The GSync II is the 2U compact version of the GSync, and provides eight output module slots. The heart of the GSync II is the GTF (GPS Time and Frequency) module within the unit. If a system needs a Primary Reference Source (PRS), the GSync II provides either Standard Positioning Service (SPS) GPS (the civil C/A signal) or SAASM Precision Positioning Service (PPS) GPS receivers (for approved users only). With GPS as the reference source, the GSync II provides a frequency accuracy of 1E-12 and a time accuracy to < 50 ns Peak to UTC, for calibrated units. The GSync II is also designed to take external inputs to provide internal frequency synchronization to the accuracy of the external source.
