3.2.1. Controlling On Screen Aspect Ratio Display

On screen = show
This menu item allows the user to enable or disable the aspect ratio on-screen display for the grid, box,
mask, and circle objects. The on-screen display will turn off after ten seconds of front panel inactivity. To
inhibit the on-screen display completely select hide. The on screen aspect ratio display shows the actual
aspect ratio of the selected object. This may be slightly different than the target aspect ratio (selected by
the object's aspect ratio mode) due to rounding of the dimensions to the closest line or pixel.

3.2.2. Choosing the Raster limits for the Mask Aspect Ratio and Size Calculation

Mask apert = prod
This menu item sets how the aspect ratio and size calculations for the mask and grid objects are
calculated. In either setting, the mask and grid objects can be positioned all the way out to the production
aperture. When you choose one of the automatic aspect ratios for the mask object, its initial size and
position will be calculated with respect to the mask aperture setting. See section 3.5.2.1 for information on
selecting the mask aspect ratio.
Select prod when you want to use the production aperture as the reference for the mask and grid object
aspect ratio and size.
Select clean when you want to use the clean aperture as the reference for the mask and grid object
aspect ratio and size.
Select analg when you want to use the nominal analog blanking as the reference for the mask and grid
object aspect ratio and size.

3.2.3. Choosing the Raster limits for the Box Size Calculation

Box % apert= prod
This menu item sets how the size percentage calculations for the box object are calculated. In either
setting, the box object perimeter can be positioned all the way out to the production aperture.
Select prod when you want to use the production aperture as the reference for the box object size
calculation.
Select clean when you want to use the clean aperture as the reference for the box object size calculation.
Select analg when you want to use the nominal analog blanking as the reference for box object size
calculation.
