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’. The shaft encoder will adjust both the U and V gains by the
same proportion of their default values. The CGAIN value is an average of the U and V
values.
Press the F3 button to allow the shaft encoder to adjust the U gain from 0 to 200%. The
shaft encoder LED will illuminate and an asterisk will appear on the display next to
UGAIN.
Press the F4 button to allow the shaft encoder to adjust the V gain from 0 to 200%. The
shaft encoder LED will illuminate and an asterisk will appear on the display next to
'VGAIN'.
Press the CAL button at any time while in this menu to set all gains to their default values
(100%).
Adjusting signal timing
Press F4 from the home menu to display the Timing menu, which provides the following
timing functions:
Output timing relative to the external reference
Chroma phase relative to burst (10 bit mode only)
Input video timing (10 bit mode only)
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)
F3: ADJ sets PHSE (chroma timing in 0.1
°
steps)
F4: ADJ sets HDEL (input timing in 37ns steps)
Different horizontal and vertical timing adjustments can be maintained for 625 and 525
line operation. However, the horizontal delay is common to both 525 and 625. Settings
are automatically maintained when the unit is powered off and restored when the unit is
powered back on.
Note:
The horizontal delay (HDEL) and phase control (PHSE) are not available in 8 bit mode.
