Scaled patterns
Internal patterns
Image 12-9
The patterns can be used for alignment or adjustment or they can be used for troubleshooting.
Scaled patterns
Scaled patterns are generated just behind the input boards and have the same timings of the selected source signal, which means
that
they can only be displayed if a source sync signal is available
.
If a source image shows some artefacts, but the scaled patterns look
fi
ne, the cause for the artefacts must be looked for in the input
board, the wires or the image generator.
If a source image shows some artefacts and the scaled pattern shows the same artefacts, the cause should be looked for in the
image processing board.
The scaled patterns are distorted according to the geometry distortion de
fi
ned in the active Geometry
fi
le.
Internal patterns
Internal patterns are generated just before the output board and are seen full screen. If the desktop image shows artefacts, but the
internal patterns look
fi
ne, then the issue will be found before the output board.
The internal patterns are not in
fl
uenced by the geometry distortion of the active Geometry
fi
le.
