Signature Control : Signature Control is used to control when the HAVE QUICK mod
ulation is present, see "Signature Control" on page 136.
Format : Used to configure the formatting of the four available HAVE QUICK outputs. The
available output formats are as follows:
STANAG 4246 HQ I
STANAG 4246 HQ II
STANAG 4372 HQ IIA
STANAG 4430 Ext HQ (Extended HAVE QUICK)
STANAG 4430 STM (Standard Time Message)
ICD-GPS-060A BCD
ICD-GPS-060A HQ
DOD-STD-1399 BCD
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 page 140 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. Refer to
for more information on Local Clocks.
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.
