The DS Polarity parameter, to the right of the DSS setting, sets the logical polarities of the Horizontal, Vertical and Composite digital sync outputs. Rotat- ing the bottom knob cycles through all possible polarity combinations. A “+” setting indicatesa posi- tive going pulse. A “-” setting indicates a negative going pulse.

The DS Gate parameter, below the DS Polarity pa- rameter, sets output gating of the Horizontal, Ver- tical and Composite digital sync outputs. Rotating the bottom knob cycles through all possible gating combinations. Gating an output “off” overrides the front panel button settings.

Sync select sets which sync outputs will be active when the format is first loaded.

Video kind sets the type of video signal you wish to generate. The 801G* supports the following video types:

Analog Y Monochrome (gray scale) component video with either composite sync added to the video or separate sync(s).

Analog RGB Color (red, green and blue) com- ponent video with either composite sync added to the green output or separate sync(s).

Analog TV Y (801GX only) Monochrome (lu- minance without any color sub-carrier) com- posite television video with controlled rise and fall times.

Analog TV EYC (801GX only) Encoded color (luminance and chrominance with color sub- carrier) composite television video with con- trolled rise and fall times. NTSC sub-carrier used when American ACS is selected and PAL sub-carrier used when European ACS is se- lected.

Analog TV YPrPb Encoded color (luminance and color difference).
