5.4 Time Code Option Cards
Signature Control : Signature Control is used to control when the HAVE QUICK mod-
ulation is present; see also "Signature Control" on page 201.
Format : Used to configure the formatting of the four available HAVE QUICK outputs. The
available output formats are as follows:
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:
The incoming input time information may be provided as local time, but System Time may be con-
figured 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 "Setting up a
Local Clock" on page 175 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.

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 Management
Screen" on page 168 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.
