(see page 1428)
Command Syntax
:TRIGger:TV:UDTV:HSYNc {{0 | OFF} | {1 | ON}}
The :TRIGger:TV:UDTV:HSYNc command enables or disables the horizontal sync
control in the Generic video trigger.
For interleaved video, enabling the HSYNc control and setting the HTIMe
adjustment to the sync time of the probed video signal allows the ENUMber
function to count only lines and not double count during equalization.
Additionally, the Field Holdoff can be adjusted so that the oscilloscope triggers
once per frame.
Similarly, for progressive video with a tri-level sync, enabling the HSYNc control
and setting the HTIMe adjustment to the sync time of the probed video signal
allows the ENUMber function to count only lines and not double count during
vertical sync.
