The following assumptions are made regarding the received IRIG-B signal. All conditions must be met for the PXI-6683 Series to be able to synchronize accurately:
To achieve proper synchronization of the NI PXI-6683 Series ensure that the IRIG-B source used conforms to the requirements listed above. Note that most IRIG-B sources conform to these requirements.

*All synchronization performance figures are based on empirical results and represent typical behavior. All figures are obtained recording the offset between PPS signals generated by two PXI-6683 Series boards, inside a closed PXI chassis, configured to synchronize to the particular time reference, at ambient room temperature. Synchronization was performed for 15 minutes before PPS offset recording began. All test durations were at least 12 hours.
†For the GPS test, two PXI-6683 Series boards were independently synchronizing to GPS and configured to generate a PPS. the specification above represents typical empirical results. Please note that GPS satellites are only guaranteed to be withing 100 ns of UTC. Therefore, the offset between any two devices synchronizing can be as high as 200 ns plus the offset of that device to GPS.
‡Sync interval of 1 second was used for IEEE 1588 tests, and all Ethernet connections were 1 Gbps unless otherwise specified.
**Hirschmann MAR1040 Gb 1588 switch used
††Netgear DS104 Hub used with 100 Mbps links
‡‡Airlink 101 Gigabit over copper switch used. For this test, a moderate amount of non-1588 Ethernet traffic was present on the switch.
***IRIG-B AM matching specification was obtained by setting two PXI-6683 Series boards to synchronize independently to the same IRIG-B AM source and generate a PPS. the offset between their PPS signals was then measured over a 12 hour period.
†††IRIG-B performance depends on IRIG-B source stability and quality.
