Without an oscilloscope

1.

Feed a grayscale signal from an Extron VTG 300/400 or
other A/V test generator to the input of the IN3252HR DA.

2.

Adjust the green gain control potentiometer until the
picture from the display device appears to have the correct
brightness and contrast.

3.

Adjust the red and blue potentiometers until the grayscale
picture appears to be gray only; no color is present.

4.

Adjust the peaking control potentiometer until the picture
appears sharp and without visible smearing.
