ProcAmp
These items allow signal levels and timings to be
adjusted.
Separate adjustments may be made for the two
input channels
Input 1 SDI
and
Input 2 SDI
.
Note that for this and other screens the following
applies to the scroll bars:
The
and
symbols at the ends of the
scroll bar allow the value to be adjusted in discrete
steps.
The numerical value will be shown next to the
scroll bars and selecting Preset
will return the
setting to the calibrated value for that item.
Input 1 SDI and Input 2 SDI Controls
These items allow the gain, black level and timing
of both signals to be adjusted.
ProcAmp Enable
When checked the ProcAmp will become enabled
for that channel and the settings will be applied to
the signal.
When unchecked the settings will revert to the
preset values.
Luma Gain
This allows the Y (luminance) gain to be adjusted
by ±6 dB in steps of 0.1 dB. Preset value is 0.0 dB.
Black Level
This allows the black level to be adjusted by
+100mV in 0.8mV steps. Preset value is 0.
C Gain
This allows the Cb/Cr (color difference) gain to be
adjusted by ±6 dB in steps of 0.1 dB. Preset value
is 0.0 dB.
Picture Position
This item allows the timing of the picture position
relative to the normal value, to be adjusted.
The timing may be adjusted by +592ns in 148ns
steps.
Y/C Timing
This item allows the timing of the chrominance
signal relative to the luminance signal to be
adjusted, (i.e. Y to Cb/Cr timing) in nanoseconds.
The timing may be adjusted by +592ns in 148ns
steps.
