Network Card

The PCIe-OSC card provides stable, accurate time and date information for a Windows PC without reference from external sources. An internal battery-backed real-time clock chip provides accuracy of ±1min/year
or <165ms per day. This PCIe card can be upgraded with a HSO (high-stability oscillator) for a stability of up to ±250ms/year.
