Description
Note: Menu item "Clamp width" is
displayed when "Clamp width ad-
justment" is activated.
The value for the clamp width is
set through the XICOR AD con-
verter.
Note: If "clamp width adjustment"
is changed from activated to deac-
tivated, menu item "Clamp width"
is hidden and the clamp width is
set to the default value.
Clamp width
The clamp width establishes the
duration of a black screen signal.
The corresponding value for the
black signal is saved during this
period as an offset value.
The offset value is kept during sig-
nal level changes in order to avoid
offset errors.
Clamping usually takes place dur-
ing the back porch of an HSYNC
because a good reference value
for black can be prepared during
this time.
If the clamp width is set too high a
black border appears because the
back porch was left and the
clamping is reaching the active
video signal.
