8.1.12 Sync Source
For convenience, you can select the Periodic Timer Sync Source using this
dropdown. You can also select it from the Periodic Sync Src tab, which also contains
controls that let you configure the Sync Source.
Selects a signal source for you to synchronize your periodic timer trigger to,
otherwise you might be triggering at some arbitrary location in the frame.
Synchronization reduces the precision requirements on the setting of the period.

8.1.13 TV Line
Selects the TV Line number on which to trigger. Line number range is dependent on
the settings of the "Standard" on page 2474 and "Field" on page 2473menus within
the TV trigger setup functions. When the line number is incremented beyond the
upper limit, the value will change to the lower limit and continue incrementing from
there. When the line number is decremented below the lower limit, the value will
change to the upper limit and continue decrementing from there.
