5-1. Line-lock Sync Mode (LL)
1. Move the cursor to the SYNC parameter 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 the cursor is on LL, press
(S). The vertical phase adjustment menu
appears on the monitor.
3. Move the cursor to COARSE. The cursor starts
blinking.
4. Supply the video output signal of the camera
to be adjusted and the reference camera video
output signal to a dual-trace oscilloscope.
5. Set the oscilloscope to the vertical rate and
expand the vertical sync portion on the oscillo-
scope.
6. Press (L) or (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 press-
ing (L) or (R).)

Note: After the sixteenth step, the adjustment
returns to the first step.
7. Move the cursor to FINE. The cursor starts
blinking.
8. Press (L) or (R) to match the vertical
phase for both video output signals as closely
as possible.
(FINE adjustment can be made up to 22.5
degrees by pressing
(L) or (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 (L) or (R) is kept pressed
for a second or longer, the “I” cursor
moves faster.
• To reset COARSE and FINE to the values
preset at the factory, press (L) or
(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.
6. White Balance Setting (WHITE BAL)
You can select one of two modes for white balance
adjustment as follows:
• ATW (Auto Tracing White Balance)
In this mode, the color temperature is monitored
continuously and thereby white balance is set
automatically. The color temperature range for
the proper white balance is approximately
2 600 - 6 000K. Proper white balance may not
be obtained under the following conditions:
1. The color temperature is out of the 2 600 -
6 000K range.
2. When the scene contains mostly high
color temperature objects, such as a blue
sky or sunset.
3. When the scene is dim.
In these cases, select the AWC mode.
Move the cursor to the WHITE BAL parameter
and select ATW. The white balance of the
camera is automatically set.
1 (1 - - 16): 0 degrees
2 (1 - - 16): 22.5 degrees
16 (1 - - 16): 337.5 degrees
