Spectracom SecureSync User Manual

1PPS Validity: Indicates “OK” (green) if the 1PPS input signal is present and valid. Indic-
ates “Not Valid” (orange) if the 1PPS input signal is either not present or is not con-
sidered valid.
Edge: Displays the selected Edge (rising of falling) of the 1PPS input that defines the on-
time point.
Offset: Displays the configured 1PPS offset values.
The 1PPS Input signal is analyzed and an absence of the signal triggers a “Not Valid” indic-
ation.
