The available options will vary according to the values of Format and
Modulation Type.
Control Function Field: IRIG signals have an optional section in the data
stream that can be used to include additional information (such as the
present year, for example). This field allows the Control Field section of the
IRIG output to be defined. The available configurations are:
Fields conform to
ation for year value, if included in this field.
Fields conform to
tains year, leap second and daylight savings time information.
Fields conform to
Field but not in the same location as RCC-2004 output (year is offset
by one position).
Fields conform to
Control Field that contains satellite lock status and time error flags.
Fields conform to
Fields confirm to
ded to support one-month leap second notification
The available options will vary according to the configurations of Format
and Modulation Type.
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).
A local clock set up through the Time Management Page—This
option will appear under the name of the local clock you have set up.
See "Local Clock(s), DST" on page 199
timescale allows a Local Clock to apply a time offset for Time Zone
and DST correction.
Amplitude: The peak-to-peak output voltage level into a 600 Ω load is
adjusted by entering a digital control value in this field. The level adjust-
ment has no effect on TTL outputs, only on AM formats. The value of 128
