Setting chrominance gains
Select the 'CHROMA' menu to allow the chrominance gains for the current mode to be
adjusted.
Press the 'F1' button to allow the shaft encoder to adjust the combined chrominance gain
from 0 to 200%. The shaft encoder LED will illuminate and an asterisk will appear on the
display next to 'CGAIN'.
Press the 'CAL' button at any time while in this menu to set chrominance gain to its
default value (100%).
Adjusting signal timing
Press F4 from the home menu to display the Timing menu, which provides the following
timing functions:
•
vertical and horizontal output timing relative to the active reference
Timing menu structure
Description
Use the ‘F’ buttons below each function to enable
the ADJ shaft encoder to change values.
F1: ADJ sets VPOS (output timing in one line steps)
F2: ADJ sets HPOS (output timing in 37ns steps)
Different horizontal and vertical timing adjustments can be maintained for 625 and 525
line operation. Settings are automatically maintained when the unit is powered off and
restored when the unit is powered back on.
The active output timing reference
The horizontal and vertical timing adjustments operate relative to one of two analogue
timing references. These are an external reference or an internal free-running clock.
When an external analogue timing reference is present serial output timing is maintained
relative to the external analogue reference.
When no external analogue timing reference present the serial output is timed to the free
running clock.
The following tables summarises the possible output timing reference sources:
