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 July, 2015,
this is 17 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. Refer to "The Time Man-
agement Screen" on page146 for more information on 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.
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 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. See also
.
Offset: Provides the ability to account for HAVE QUICK cable delays or other latencies
in the HAVE QUICK outputs. The Offset values are entered in nanoseconds (ns). The avail-
able Offset range is –500 to +500 ms.
HAVE QUICK Output: Status Window
To view the current settings of a HAVE QUICK Output, go to its Status window. For instructions,
see: "Viewing Input/Output Configuration Settings" on page347.
The Web UI list entries for this card are: HAVE QUICK out, BNC and HAVE QUICK Out, RS-485.
The outputs are named: HQ Output [number].
Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out-
puts start at1, because of the built-in outputs).
