10. Synchronization Setting (SYNC)
This model accepts the VBS signal (color composite video
or blackburst signal) and VS signal (B/W composite video
or composite sync signal ) for gen-lock operation.
It also accepts the combined vertical (VD) and horizontal
(HD) drive pulse.
Important Notices:
• The sync mode priority is as follows:
1. Color composite video signal (EXT(VBS))
2. B/W composite video signal (EXT(VS))
3. HD/VD signal (EXT(H/V))
4. Internal sync (INT)
• When the internal sync (INT) mode is to be used, no
gen-lock input signal should be supplied to the gen-
lock input connector on the rear panel of the camera
control unit.
• When the VBS or VS gen-lock mode is to be used, sup-
ply the gen-lock input signal to the gen-lock input con-
nector (VBS/HD) on the rear panel of the camera con-
trol unit.
• The VBS gen-lock mode has its own menu for horizontal
and subcarrier phase adjustments. When the cable
length of the video output or the gen-lock input is
changed, horizontal and subcarrier phase must be re-
adjustable.
• The VS gen-lock mode has its own menu for horizontal
phase adjustments. When the cable length of the video
output or the gen-lock input is changed, the horizontal
phase must be re-adjusted.
• When the HD/VD pulse is to be used, supply them to
the gen-lock signal input connector (VBS/HD) and the
VD input connector (VD) on the rear panel of the cam-
era control unit.
10-1. Internal Sync Mode (INT)
It is not necessary to perform this setting.
10-2. VBS Gen-lock Mode (EXT(VBS))
1. Move the cursor to the SYNC parameter.
2. Connect the coaxial cable for the blackburst or com-
posite color video signal to the gen-lock input connec-
tor (VBS/HD).
3. Confirm that the INT parameter changed to EXT(VBS)
on the menu.
Caution:
The gen-lock input signal should meet the EIA
RS-170A specifications and should not contain jit-
ter, such as a VCR (VTR) playback signal, as it
could disturb synchronization.
4. After confirming that the cursor is on EXT(VBS), press
the PAGE button. The SYNC menu appears on the mon-
itor screen.
Horizontal Phase Adjustment (H PHASE)
1. Move the cursor to H PHASE. The cursor starts blinking.
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
.
Note:
To reset H PHASE to the values preset at the fac-
tory, 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 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 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.
