6. Synchronization Setting (SYNC)
Select one of the three sync source modes. The priority is as follows.
(1) Multiplexed Vertical Drive (VD2) (Highest priority)
(2) Line-lock (LL)
(3) Internal Sync (INT) (Lowest priority)
6-1. Line-lock Sync Mode (LL)
The line-lock mode has a submenu for line-lock vertical phase adjustment. If the camera
installation is relocated, check the vertical phase adjustment again since the AC line phase
may be different.
1. Move the cursor to SYNC and select LL.
Note:
The settings in this menu can be
made only when the multiplexed
vertical drive signal (VD2) is not
supplied to the camera.
2. After confirming that the cursor is on LL,
press
I
(S). The vertical phase adjust-
ment menu appears on the monitor
screen.
3. Supply the video output signal of the camera to be adjusted and the reference camera
video output signal to a dual-trace oscilloscope.
4. Set the oscilloscope to the vertical rate and expand the vertical sync portion on the
oscilloscope.
5. Move the cursor to COARSE. The cur-
sor is highlighted.
6. Press
I
(L) or
I
(R) to match the
vertical phase for both video output
signals as closely as possible.
(COARSE adjustment can be incre-
mented in 16 steps by 22.5 degrees by
pressing
I
(L) or
I
(R).)
Note:
After the sixteenth step, the
adjustment returns to the first step.
7. Move the cursor to FINE.
8. Press
I
(L) or
I
(R) to match the vertical phase for both video output signals as
closely as possible.
(FINE adjustment can be made by up to 22.5 degrees by pressing
I
(L) or
I
(R).)
Notes:
• When the “I” cursor reaches the “+” end, it jumps back to “–”. At the same time,
COARSE is incremented by one step to enable a continuous adjustment. The
reverse takes place when the “I” cursor reaches the “–” end.
• When
I
(L) or
I
(R) is kept pressed for a second or more, the “I” cursor moves
faster.
• To reset COARSE and FINE to the values preset at the factory, press
I
(L) and
I
(R) simultaneously. COARSE and FINE adjustments are preset at the factory to
zero-crossing of the AC line phase.
• If the AC line contains noise (spike noise, etc.), the stability of the vertical phase of
the camera video output signal may be disturbed.
7. White Balance Setting (WHITE BAL)
You can select one of four modes for white balance adjustment as follows.
The factory default setting is ATW1.
7-1. ATW1 (Auto-Tracing White Balance 1)
Move the cursor to WHITE BAL and select ATW1.
In this mode, the colour temperature is monitored continuously and thereby white balance is
automatically set. The colour temperature range for the proper white balance is approxi-
mately 2 600 - 6 000K. Proper white bal-
ance may not be obtained under the follow-
ing conditions:
1. The colour temperature is out of the 2
600 - 6 000K range.
2. When the scene contains mostly high
colour temperature objects, such as a
blue sky or sunset.
3. When the scene is dim.
In these cases, select the AWC mode.
7-2. ATW2 (Auto-Tracing White Balance 2)
Auto-tracing white balance in sodium light mode (ATW2)
When you select ATW2 for sodium light, white balance is set automatically (no operation
needed).
Note:
ATW1 and ATW2 do not appear for WHITE BAL on the system controller setup menu.
7-3. Automatic White Balance Control Mode (AWC)
In this mode, accurate white balance is obtained within a colour temperature range of
approximately 2 300-10 000K.
1. Move the cursor to WHITE BAL and
select AWC
→
PUSH SW.
2. Press
I
(S) to start the white balance
setup. The PUSH SW is highlighted to
indicate that the white balance is being
set.
3. When the white balance setting is completed, the PUSH SW returns to normal display.
Note:
If white balance is not set, the PUSH SW is being highlighted.
4. When you want to adjust the white bal-
ance manually, press
I
(R) to select
AWC and press
I
(S). The AWC
menu appears on the monitor screen.
(When ATW1 or ATW2 is selected,
pressing
I
(S) displays the ATW1 or
ATW2 menu.)
1 (1 - - 16): 0 degrees
2 (1 - - 16): 22.5 degrees
