5. Move the cursor to the RGB SYNC parameter.
6. Select 4.0V or 0.3V according to the RGB monitor input
level.
Horizontal Phase Adjustment (H PHASE)
1. Move the cursor to H PHASE. The cursor starts blink-
ing.
2. Supply the video output signal of the camera to be
adjusted and the reference gen-lock input signal to a
dual-trace oscilloscope.
3. Set the oscilloscope to the horizontal sync portion on
the oscilloscope.
4. Adjust the horizontal phase by pressing
A
or
B
. The
adjustable range is 0-1.5
µ
s.
Note:
To reset H PHASE to the values preset at the
factory, press
A
and
B
simultaneously. The H
PHASE is reset at the factory setting.
Subcarrier Coarse Phase Adjustment (SC COARSE)
1. Move the cursor to SC COARSE parameter on the
SYNC menu. The cursor starts blinking.
2. Press
A
or
B
to match the color (hue) of the camera's
video signal, when observed at the output of the
Special Effect Generator (SEG) or Switcher, as closely
as possible the color of the original scene. (The SC
COARSE adjustment can be incremented in steps of
90 degrees (4 steps) by pressing
A
or
B
.)
Note:
After the fourth step, the adjustment returns to the
first step.
Subcarrier Fine Phase Adjustment (SC FINE)
1. Move the cursor to SC FINE on the SYNC menu. The
cursor starts blinking.
2. Press
A
or
B
to match the color (hue) of the came-
ra's video signal, when observed at the output of the
Special Effect Generator (SEG) or Switcher, as closely
as possible the color of the original scene.
The SC FINE adjustment has a range of 90 degrees of
color shift.
Notes:
• When the "I" cursor reaches the "+" end, it jumps back
to "–" . At the same time, SC COARSE is incremented
by one step to enable a continuous adjustment. The
reverse takes place when the "I" cursor reaches the "–"
end.
For more accurate adjustment, supply both the original
camera video output signal and the effect output video
signal (program output video signal) of the special
effects generator (SEG) to a vectorscope and compare
the chroma phase of both signals.
• To reset SC FINE to the values preset at the factory,
press
A
and
B
simultaneously. The SC FINE is reset
at the factory setting.
6-3. VS Gen-lock Mode (EXT(VS))
1. Move the cursor to the SYNC parameter.
2. Connect the coaxial cable for the composite sync or
composite B/W video signal to the gen-lock input con-
nector.
3. Confirm that the INT parameter changed to EXT(VS) on
the menu.
Caution:
The gen-lock input signal should meet the
EIA RS-170 specifications and should not contain
jitter, such as a VCR playback signal, as it could
disturb synchronization.
4. After confirming that the cursor is on EXT (VS), press
the PAGE button. The phase adjustment menu
appears on the monitor screen.
5. Move the cursor to the RGB SYNC parameter.
6. Select 4.0V or 0.3V according to the RGB monitor input
level.
7. Move the cursor to H PHASE. The cursor starts blink-
ing.
