Line-lock Sync Mode (LL)
• Display the setup menu.
• If necessary, refer to "Setup Menu Display" on page 8 for details on
displaying the setup menu on the monitor screen.
• Move the cursor to "SYNC" and select the line-lock "LL" mode by using
the joystick. This setup can be only made when the multiplexed
vertical drive (VD2) pulse is not supplied to the camera.
• After confirming that the cursor is on "LL", press the CAM (SET) button
on the rear panel. The following vertical phase adjustment menu is
then displayed on the monitor.
• Move the cursor to "COARSE" by using the joystick. The cursor starts
blinking.
• Connect the video output signal of the camera to be adjusted and the
referenced camera video output signal (for example, Camera 1) to the
dual-trace oscilloscope.
• Set the dual-trace oscilloscope to the vertical rate and expand the
vertical sync portion on the oscilloscope.
• Control the joystick to match as closely as possible the vertical
phases for both video output signals. (The coarse adjustment can be
incremented for every 42 degrees (9 steps) by using the joystick.)
Note: After the 9 step, the adjustment returns to the first step.
• Move the cursor to "FINE" by using the Down switch. The cursor
starts blinking.
• Use the joystick to match as closely as possible the vertical phases
for both video output signals. (Fine adjustment can be made for up to
42 degrees by using the joystick.)
