Vectorscope and Waveform Monitor while adjusti ng
the Mode functions)

1. Contrast (video gain) - adjusts the range between

full White and full Black. At its minimum level,
White and Black converge at +47IRE. At near the
maximum level, Black rests at 0 IRE and White at
112IRE. Each step of adjustment is approximately
0.3IRE. Caution should be observed not to
exceed this range. Digitally created artifacts will
appear across the video frame if this adjustment is
overdriven.

2. Brightness (setup) - adjusts the level of DC offset

of the active video. At its minimum level, Black
rests at 0IRE and Whiter Than White at 27IRE. At
the maximum level, Black rides at 69IRE and
Whiter Than White at 112IRE. Each step of
adjustment is approximately 0.3IRE.

3. Saturation - adjusts the amount of amplitude

allotted to the Chromanance. At its minimum level
(assuming Contrast and Brightness are set to
NTSC standards), color vectors align to the center
of the color boxes on a Vectorscope. At its
maximum levels, color vectors amplitude are
doubled.

4. Hue (phase) - adjust the phase angle of the

Chromanance with respect to subcarrier. 0-360
degrees of phase can be achieved.

5. H-Phase - adjusts the Horizontal Phase

relationship with respect to the reference video
source. Depress either the Inc or the Dec button
four (4) times for each 0.3uS step.

6. SC-Phase - adjusts the Subcarrier Phase

relationship with respect to the reference video
