Aux Ref Input

If an Aux Ref input is available and enabled, the XLi assumes that Aux Ref is a better frequency source
than its own oscillator. If a timing reference is not available (or becomes unavailable) and Aux Ref is
enabled, the XLi locks to the Aux Ref input. Under those conditions, frequency output accuracy is equal
to the reference < 1 x 10
Note:
Manually set the time and date, when using 1 PPS or Aux Ref as the primary references. Set the
date (year) when using IRIG A000, A130, B000, B120, or NASA 36 as the primary reference.
