VideoPictureCommandGroup
The video picture features as well as triggering on a video signal are included
standard with the MDO3000 series models. These features require the DPO4VID
application module for use with MSO/DPO4000B and the MDO4000/B/C models.
Use the video picture commands for video picture functionality.
