vertically to obtain the correct aspect ratio. This decimation may cause some
artifacts. This behavior may be evident on a sweep signal. Also see the online
help for the Picture Aspect Ratio for related information. Display can be set to
include Closed Captioning text or Teletext subtitles overlaid on the picture.
