Controlling the Vector

(For Composite analog video input only) A vector display has two

individual properties: phase and magnitude. To control the phase of the

vector, press the PHASE button and turn the CURVED ARROW knob.

The magnitude is controlled by the Variable Gain. Press the VAR button

and then use the CURVED ARROW knob. Variable gain can be used in all

formats.

Gain Buttons

The standard gain in the vector is x1.0. The VTM Series can be used to set the gain

amplification in the video signal using the Gain group of buttons. The gain setting

appears in the upper-left portion of the vector pane, as shown in Figure 3-29.

Gain is displayed on the screen, the Vector Variable Gain can be adjusted

using the CURVED ARROW KNOB. The gain is adjusted in increments of

0.01. The Variable Gain range is x0.50 to x50.00.
