Use of Time Fault Discrete: There are two options:
Enabled: The TFD input signal is used to validate the STANAG input.
Disabled (default): The TFD input signal is ignored.
Use of Bit Synchronization (BS): There are two options:
Enabled: The second STANAG input (TOD 2) is used to receive the BS (Bit
Stream) signal used with STANAG 4430-STM. When BS is active, the con-
figuration of TOD2 is superseded and only used for BS.
Disabled: The second STANAG input (TOD 2) can be used to receive an inde-
pendent TOD.
Timescale: Used to select the time base for the incoming time code data. The
entered Timescale is used by the system to convert the time in the incoming data
stream to UTC time for use by the System Time. The available choices are:
UTC: Coordinated Universal Time ("temps universel coordonné"), also
referred to as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as of 15-Febru-
ary-2021, this is 18 seconds ahead of UTC time).
A local clock set up through the Time Management Page: Refer to "The
Time Management Screen" on page166 for more information on how to con-
figure and read the System Time. Local timescale allows a Local Clock to
apply a time offset for Time Zone and DST correction.
The incoming input time information may be provided as local time, but Sys-
tem Time may be configured as UTC time, so internal computations need to
be performed. With the Timescale field set to “Local”, select the name of a
previously created Local Clock. The Time Zone and DST rules, as configured
in the Local Clock will be applied to the front panel time display. Refer to for
more information on Local Clocks.
Reference Selection: Selects TOD 1 or TOD 2 (configured below) which TOD sig-
nal is used for synchronization.
