J3 Input – Auxiliary Reference
Auxiliary Reference (Aux Ref):
See “
F113 – J3 Input Configuration (Aux Ref)” on page 104.
1 PPS – Pulse Per Second Output
If a time reference is unavailable, 1 PPS is as stable as the frequency reference (e.g., OCXO, Aux Ref).
CODE – Time Code Output
Many IRIG devices only look at the BCD portion of the IRIG frame. Devices that use IRIG A002, B002
and B122 should be able to synchronize with the XLi’s time code outputs.
