Subcarrier Fine Phase Adjustment (SC PHASE)
1. Move the cursor to SC PHASE on the SYNC menu. The
cursor starts blinking.
2. Press
A
or
B
to match the color of the camera's video
signal, when observed at the output of the Special
Effect Generator (SEG) or Switcher, as closely as possi-
ble the color of the original scene.
The SC PHASE 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 PHASE to the values preset at the factory,
press
A
and
B
simultaneously. The SC PHASE is reset
at the factory setting.
10-3. 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 (VBS/HD).
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 (VTR) 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 H PHASE. The cursor starts blinking.
6. Supply the video output signal of the camera to be
adjusted and the reference gen-lock input signal to a
dual-trace oscilloscope.
7. Set the oscilloscope to the horizontal rate and expand
the horizontal sync portion on the oscilloscope.
8. Adjust the horizontal phase by pressing
A
or
B
.
10-4. External HD/VD Mode (EXT(H/V))
1. Connect the coaxial cable for the external HD and VD
signal to the gen-lock input connector (VBS/HD) and
the VD input connector (VD) respectively.
2. Confirm that the INT parameter changed to EXT(H/V) on
the menu.
