APPENDIX
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
Clock will be applied to the front panel time display. Refer to for more inform-
ation on Local Clocks.
For each Time of Day the following settings are displayed:
460
Threshold to activate
value threshold. Below this value, the TFD is high, otherwise the TFD is low.

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the configuration of TOD 2 is superseded and only used for BS.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: Indicates the time base for the incoming time code data. The
entered Timescale is used by the system to convert the time in the incom-
ing 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
22-August-2023, 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 page 186
how to configure and read the System Time. Local timescale allows a
Local Clock to apply a time offset for Time Zone and DST correction.
Signature Control: Indicates when the signal is present. This function
allows the modulation to stop under certain conditions, see
trol" on page 183.
TOD Format: The user-selectable format being used. Available formats
include:
TFD: If the TFD is activated, indicates the TFOM
(BS):
