Adjustment Of Phase In Vbs Genlock Mode (Vbs) - Panasonic WV-CLR930 Bedienungsanleitung

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.

Step 1
Provide a VBS signal to the external synchro-
nizing input connector on the rear side of the
camera.
→ The
"SYNC"
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.

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 °
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.
