The user can either have the output video go to black or freeze the last good

This control allows you to select the reference video for the frame synchronizer
output timing. The reference may either be an externally supplied color black or
you may use the input video as a reference. Optionally, the synchronizer can be
free-run if the "none" option is selected.
If the card is installed in a 7700FR-G frame, two reference inputs are available
on the frame that supply video to every card. Either of these two inputs may be
selected as reference sources.
When genlocking to the input video, make sure to adjust the video H and V
output phase controls to set the total processing delay. The H and V Delay
indicators show you the time-of-flight of the video and audio through the frame
synchronizer.
Not available will be displayed if the +S option was not purchased.
