The DCS-200 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.

Use the following steps to adjust sample clock phase of each scaler, for inputs whose
"type" is analog.

DCS-200 • User's Guide
When sampling is set to OverSample, values represent the oversampling factor
being used.
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.
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.
Adjustment range: -16 to 15
Default: 0
From the Input Menu, navigate to the Timing Adjust Menu, and scroll to the
Phase A or Phase B line.
In the Inputs Section, select an input whose "type" is analog.
TAKE the input to Program. The button lights solid.
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.
On the Timing Adjust Menu, note that one of the two Phase lines will be
bracketed, and the other will be unbracketed. When you press TAKE, the
brackets will switch positions. The un-bracketed line is the active scaler.

On the selected input, put up a Burst pattern. For example, if the source is a
computer, use a program such as DisplayMate
Scroll to the unbracketed Phase line, and press SEL.
Use the Adjust knob to tweak the burst pattern for the maximum visual clarity and
a minimum amount of visual noise, then press SEL to accept the new value.
