SyncBox N2X - PTP Slave
After decoding valid time information from a PTP Master, the system sets its own PTP seconds and nanoseconds
accordingly. The PTP offset calculated by the PTP driver software is used to adjust the master oscillator of the
SyncBox N2X. This allows the PTP Slave to generate very high accuracy output signals (10 MHz/1PPS/IRIG).
