On the DPO3000/MSO3000+ how do you get the video IRE/mv graticule?

The IRE/mv graticule is not a menu selection. There are two ways to get this graticule.

1. The graticule is automatically enabled when you attach a video signal and press AUTOSET.

2. Set trigger mode to video, adjust vertical scale until 143 mv/div is selected. This setting is available only when video trigger is selected.

IRE will be the scale on the left side of the screen, and mv scale will be on the right side of the screen.
