Panasonic WV-CL930, WV-CL934 operating instructions Adjustment of phase in VBS genlock mode VBS

Adjustment of phase in VBS genlock mode (VBS)

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. Follow the procedure below to adjust the phase.

Move the cursor horizontally to adjust the horizontal phase with use of the right or left button.

Adjustable range: 0 to –2.0 µs

Step 5

Move the cursor to "SC COARSE" (subcarrier coarse adjustment), and use the following 4 steps to match the real color of the subject with the color of the effect output signal (pro- gram output video signal) of the special effect device (SEG) with use of right or left button.

1 (1--4) : 0 °/2 (1--4) : 90 °/3 (1--4) : 180 °/

4 (1--4) : 270 °

RET TOP END

Step 1

Provide a VBS signal to the external synchro- nizing input connector on the rear side of the camera.

→ The "SYNC" setting automatically changes to "EXT (VBS)".

Step 2

Move the cursor to "EXT (VBS)" and press the setting button.

→The "SYNC" screen appears.

Step 3

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

Step 4

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

Step 6

Move the cursor to "SC FINE" (subcarrier fine adjustment), and move the cursor horizontal- ly with use of the right or left button to match the real color of the subject with the color of the program output video signal.

Notes:

•When the cursor moves to the right end "+" position, the cursor moves to the left end "-" position. At the time, the setting value of "SC COARSE" is incremented by 1, and adjustment is continuously per- formed.

•Holding down the right or left button for more than 1 second increases the cursor moving speed.

•To achieve high precision adjustment, provide the video signal of the camera and program output signal to a vector chromaticity indicator to compare the macro phases of both signals.
