Signature Control: Displays the current configuration of Signature Control. See "Sig
nature Control" on page136.
Frequency: Indicates the configured frequency of the 1PPS output signal.
Offset: Displays the configured Offset (to account for cable delays or other latencies).
Edge: Shows if the on-time point of the 1PPS output is the rising or falling edge of the
pulse.

displayed in nanoseconds (ns). The default Pulse Width is 200 milliseconds.
1PPS Input: Edit Window
To configure the settings of the PPS Input (also referred to as ‘Reference’), go to its Edit win
dow. For instructions, see: "Configuring Option Card Inputs/Outputs" on page330.
The Web UI list entries for these cards are:
1PPS In/Out
1PPS In/Out, Fiber
The connector number for the input is: J1
Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out
puts start at1, because of the built-in outputs).
The Edit window allows the configuration of the following settings:
Edge: The operator can select either the rising or the falling edge as the input time ref
erence (defines the on-time point of the signal).
Offset: It is possible to add an offset to the input signal (to account for cable delays),
with a resolution of 5ns and a positive or negative value of 500ms maximum.
