Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out-
puts start at1, because of the built-in outputs).
The fields available are:
Signature Control: Used to control when the 1PPS output signal will be present. See: "Sig-
nature Control" on page141.
Offset: Used to account for 1PPS cable delays or other latencies in the 1PPS output. The
Offset value is entered and displayed in nanoseconds (ns). The available Offset range is
-500 to +500ms.
Edge: The operator can select if the output signal is a positive (reference on the rising
edge) or a negative (reference on the falling edge) pulse.
Pulse Width: Configures the Pulse Width of the 1PPS output. The Pulse Width is entered
and displayed in nanoseconds (ns). The default Pulse Width is 200 milliseconds.
