6-3. Line-lock Sync Mode (LL)
Note:
The line-lock (LL) sync mode is not available
when the camera operates on DC power.
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 that the cursor is on LL, press
I
. The vertical phase adjustment menu appears
on the monitor.
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 oscillo-
scope.
5. Move the cursor to COARSE.
6. Press
L
or
M
to match the vertical phase for
both video output signals as closely as possible.
(COARSE adjustment can be incremented in 16
steps by 22.5 degrees by pressing
L
or
M
.)
Note:
After the sixteenth step, the adjustment
returns to the first step.
1 (1 - - - 16): 0 degree
2 (1 - - - 16): 22.5 degrees
16 (1 - - - 16): 337.5 degrees
7. Move the cursor to FINE.
8. Press
L
or
M
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
M
.)
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 con-
tinuous adjustment. The reverse takes place
when the “I” cursor reaches the “–” end.
• When
L
or
M
is kept pressed for a second
or more, the “I” cursor moves faster.
