Have Quick Input

See “HaveQuick/1 PPS Time and Frequency Reference(87-8016-3)” on page 216.

1 PPS Input

See “HaveQuick/1 PPS Time and Frequency Reference(87-8016-3)” on page 216.

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

-12

.

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. 
See 

F3 – Time & Date (page 50)
