About the IRIG Output Resolution

The IRIG output signals are generated from SecureSync's System Time, which can be synced to one or more external input references (such as GPS, IRIG, PTP, etc). The accuracy of the System time to true UTC time is dependent upon what the selected external reference is (with GPS typically being the most accurate reference for the system to sync with).

IRIG AM synchronization of a device to its IRIG source is typically measured in the tens of microseconds, while synchronization using a IRIG DCLS signal can typically provide around 100 nanoseconds or so (plus the cable delays between SecureSync and the other device, as well as the processing delays of the other system itself).

IRIG AM functionality is available through an option card.

Note that all IRIG outputs has its own available ‘offset’ capability, which is configurable via SecureSync’s Web UI, to help account for cabling and processing delays of the device each output is connected with.
