4. Operation
Using the Setup Menu
~
When
1:1 Sampling
is selected, the system provides pixel-for-pixel
sampling, and generally better image quality.
~
When
Oversample
is selected, the system performs multiple samples
for every pixel, with a resulting “softer” image.
~
Oversample
is only available for RGB and YP
b
P
r
analog inputs.
~
All other input types have defined sample clocks that are inherently
1:1
.
If the input is set to one of the other types, the value is
[1:1]
.
•
Phase A
,
Phase B
— These two selections are advanced features which enable
you to adjust the sample phase of the system’s two scalers. Typically, they do not
need to be adjusted. Refer to the “
for instructions.
The six “
Active Area
” values are initially filled in by the
Auto Config
command, or set to
their default values. You can adjust values for Analog RGB or YP
b
P
r
sources only, but
digital and decoded sources show values in brackets. Please note:
•
When sampling is set to
1:1
, values are the true timing measurements for the
analog RGB or YP
b
P
r
inputs.
•
When sampling is set to
OverSample
, values represent the oversampling factor
being used.
For all
Horizontal
“active area” fields, all units are measured in pixels:
•
H Total
— adjusts the total pixel count per line. This value cannot be adjusted if
the input type is
DVI
/
SDI
.
•
H Position
— adjusts the offset of start of active area from H sync.
•
H Active
— sets the size of the active area.
For all
Vertical
“active area” fields, all unit are measured in lines.
•
V Total
— indicates the total line count per frame. This value is measured, and
can never be adjusted. Its value will always be shown in brackets.
•
V Position
— sets the offset of start of active area from V sync.
•
V Active
— sets the size of the active area.

The CP-100 has two A-to-D converters, which are referred to as
A
and
B
in the
Timing
Adjust Menu
. The sample phase value of each scaler is initially filled in by the
Auto
Config
command, or set to the default value of
0
(zero). If required, advanced users can
fine-tune the image by adjusting the sample clock phase of each scaler directly —
but only
for inputs whose “type” is analog
.
•
Adjustment range
: -16 to 15
•
Default
: 0
Use the following steps to adjust sample clock phase of each scaler, for inputs whose
“type” is analog.
1.
From the
Input Menu
, navigate to the
Timing Adjust Menu
, and scroll to the
Phase A
or
Phase B
line.
2.
In the
Inputs Section
, select an input whose “type” is analog.
3. TAKE
the input to Program. The button lights solid.
4.
Pend the
same input
for the next transition. In this mode, only one button will now
be lit solid, and no buttons will be blinking.
