Adjustment of phase in power supply synchronization mode (LL)

The adjusting video signal of the camera and the criterial external synchronizing input signal are connected to a 2-input oscilloscope and the phase is adjusted.

Note:

Movement of the camera or presence of a spike noise in the power line may cause vertical phase change. In such a case, adjust the phase again.

Follow the procedure in the next page to adjust the phase.

Step 1

Set "SYNC" to "LL" and press the setting but- ton.

The "SYNC" screen appears.

Step 2

Connect the video output signal and external synchronizing input signal of the camera to a 2-input oscilloscope, and move the cursor to "COARSE".

Step 3

Adjust the oscilloscope to the vertical rate, and extend the vertical synchronizing part of the oscilloscope.

Move the cursor horizontally to adjust the ver- tical phase with use of the right or left button. The phase can be adjusted in 16 steps by 22.5 degrees.

1 (1--16) : 0 °/2 (1--16) : 22.5 °/ ...../16 (1--16)

: 337.5 °

Step 4

Move the cursor to "FINE", and move the cur- sor horizontally with use of the right or left button to adjust both vertical phases.
