Enabled: The TFD signal uses the "Threshold to activate" value to
provide the level of TFD.
Disabled: The TFD signal is always valid.
Threshold to activate
TFOM value threshold. Below this value, the TFD is high, otherwise the TFD
is low.
Generate Bit Synchronization
Enabled: The second STANAG signal (TOD 2) is used to send the BS
(Bit Stream) signal used with STANAG 4430-STM. When BS is active,
the configuration of TOD 2 is superseded and only used for BS.
Disabled: The second STANAG signal (TOD 2) can be used to send
an independent 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 avail-
able 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
22-August-2023, this is 18 seconds ahead of UTC time)

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 System
Time may be configured as UTC time, so internal computations need to be per-
formed. 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
