The DS Polarity parameter, to the right of the DSS
setting, sets the logical polarities of the Horizontal,
V
ertical 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).
