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.)
