Level and Peaking Controls

a

Level and Boost control — The Level and Boost control alters the video output voltage

to affect the brightness of the displayed image. Adjust the
knob while viewing the displayed image to set the level/boost
that provides the best picture quality.
For a typical (0.7 Vp-p) analog computer video input, adjust
the output is as follows:

z

At the minimum level setting (the counterclockwise limit of this control), the
interface outputs video at 0.5 Vp-p.

z

Unity level is 0.7 Vp-p, the same as the input signal. Set the control to just before
the boost range (indicated by the red line on the interface, the shaded area on the
illustration at right) to output unity level video.

z

At the maximum level setting (the clockwise limit of this control), the interface
outputs video at 1.45 Vp-p.
