Sync Gate Buttons

The buttons in this group select the type of sync signal that is used to synchronize the display. De- pending on a particular format’s settings, more than one type of sync can be selected by pressing two buttons at a time.

The ACS (Analog Composite Sync) push-but- ton causes analog sync to be output on one or more of the analog video outputs.

The DCS (separate Digital Composite Sync) push-button causes a separate digital compos- ite sync signal (CS) to be output.

The DSS (separate Digital Separate Sync) push- button causes separate digital horizontal and vertical sync signals to be output.

A default sync type is automatically selected whenever a new format is selected. Not all sync types are available with all formats. For example, digital video formats will not allow analog com- posite sync to be selected. If a button will not light up when pressed, then the corresponding sync type is unavailable.

Re-depressing a sync gate button causes the selected sync to be toggled either on or off. When toggled off, no sync will be sent to the display and the dis- play will be allowed to free-run.

The individual settings are overridden (gated off) whenever the master outputs button is turned off.

Outputs Button

This is the master output signal control. When the master output control is turned off, all of the signal outputs of the generator are disabled.
