Timing the PDR100 to the System
In a number of applications it will be necessary to time the PDR100 to the system.
The internal reference for the PDR100 is the Reference Genlock. The PDR100 is
shipped with 0 delay in the reference and the output timed to the reference. The
reference delay and the output timing can be set separately; however, if the reference
is moved, the output will be moved a corresponding amount and should only be
adjusted if the range of the Output Delay is insufficient.
Setting the Reference Genlock Delay
The Reference Genlock advance is set from the PDR100 Configuration Tool, which
will only run if the VDR panel is already running. See the “User Manual” for more
information on the VDR panel. The actual setting is in software and is set from the
Configure System menu, by selecting Configure Reference Genlock. When
Reference Genlock is selected, a panel containing three settings is shown on the
screen of the monitor:
Fields, which is initially set to 0.
Lines, which is initially set to 0.
Vernier, which is initially set to 0 advance.
Each of these can be set with the mouse in the select and drag mode.
Setting the Output Delay
The output of the PDR100 can be advanced up to 2
1
/
2
lines, or delayed up to 148 lines
from the Reference Genlock. The output delay is set from the PDR100 Configuration
Tool. The settings are in software and are reached from the Configure System menu,
by selecting Configure Video Output and then selecting the appropriate output. There
are two settings that can be made using the mouse in the select and drag mode:
Line, which is initially set to 0, but can be advanced two lines or delayed 148 lines.
Fine, which is initially set to 0, but can be set to advance or delay at 74 ns per click.
If the Reference Delay has been changed, the Output Delay will also be affected, and
will need to be reset.
