Panasonic WV-CP470, WV-CP474 6. Synchronization Setting (SYNC)

6. Synchronization Setting (SYNC)

You can select internal sync (INT) mode or line-lock (LL) mode. Additionally, this model

accepts the VBS signal (composite color video or blackburst signal) and VS signal (B/W

composite video or composite sync signal). The VD2 signal (multiplexed vertical drive sig-

nal) with the composite video output signal from external equipment such as a matrix

switcher is also acceptable.

Whenever the VD2 signal is supplied to this camera, the camera automatically switches to

the VD2 sync mode.

1. Move the cursor to SYNC and select LL or INT.

The factory default setting is INT.

2. Press I.

If LL is selected, the SYNC menu appears. (If INT is selected, the synchronization mode

is automatically set to internal sync pulse, and the menu is not displayed.)

Important Notices:

1. The priority for the sync modes is as follows:

1. Multiplexed vertical drive (VD2) (Highest priority)

2. Line-lock (LL)

3. Composite color video or blackburst signal (VBS)

4. Composite B/W video or composite sync signal (VS)

5. Internal sync (INT) (Lowest priority)

2. When the internal sync mode is to be used, select INT. No gen-lock input signal should

be supplied to the GEN-LOCK connector on the rear panel.

3. Whenever the multiplexed vertical drive pulse (VD2) is supplied to the camera from an

external equipment such as a matrix switcher, the camera sync mode is automatically

switched to the VD2 mode.

4. When the VBS or VS gen-lock mode is to be used select INT from this menu and supply

the gen-lock input signal to the GEN-LOCK connector on the rear panel.

5. The VBS gen-lock mode has a submenu for horizontal and subcarrier phase adjust-

ments. When the cable length of the video output or the gen-lock input is changed, the

horizontal and subcarrier phase must be re-adjusted.

6. The VS gen-lock mode has a submenu for horizontal phase adjustments. When the

cable length of the video output or the gen-lock input is changed, the horizontal phase

must be re-adjusted.

7. The line-lock mode has a submenu for line-lock vertical phase adjustment. If the cam-

era installation is relocated, check the vertical phase adjustment again since the AC

line phase may be different.

6-1. VBS Gen-lock Mode [EXT (VBS)]

1. Move the cursor to SYNC and select

INT.

2. Connect the coaxial cable for the

blackburst or composite color video

signal to the gen-lock input connector.

3. Confirm that INT changed to EXT (VBS)

on the menu.

Note: The gen-lock input signal should

meet EIA RS-170A specifications

and should not contain jitter, such

as a VCR playback signal, as it

could disturb synchronization.

4. After confirming that the cursor is on

EXT (VBS), press I. The phase

adjustment menu appears on the moni-

tor screen.

5. Supply the video output signal of the

camera to be adjusted and the refer-

ence gen-lock input signal to a dual-

trace oscilloscope.

6. Set the oscilloscope to the horizontal rate and expand the horizontal sync portion on the

oscilloscope.

7. Move the cursor to H PHASE.

8. Adjust the horizontal phase by pressing Lor M. The adjustable range is 0-2.0 µs.

9. Move the cursor to SC COARSE.

10. Press Lor Mto match the chroma

phase of the camera’s video signal,

when observed at the output of the

special effect generator (SEG) or

switcher, as closely as possible to the

color of the original scene. (SC

COARSE adjustment can be increment-

ed in steps of 90 degrees (4 steps) by

pressing Lor M.)

Note: After the fourth step, the adjust-

ment returns to the first step.

11. Move the cursor to SC FINE.

12. Press Lor Mto match the color (hue) of the camera’s video signal, when observed

at the output of the special effect generator (SEG) or switcher, as closely as possible to

the color of the original scene.

The SC FINE adjustment has a range of 90 degrees of color shift.

Notes:

•When the “I” cursor reaches the “+” end, it jumps back to “–” . At the same time,

SC COARSE is incremented by one step to enable a continuous adjustment. The

reverse takes place when the “I” cursor reaches the “–” end.

•When Lor Mis kept pressed for a second or more, the “I” cursor moves faster.

•For more accurate adjustment, supply both the original camera video output signal

and the effect output video signal (program output video signal) of the special

effect generator (SEG) to a vectorscope and compare the chroma phase of both

signals.

•To reset SC COARSE and SC FINE to the values preset at the factory, press L

and Msimultaneously.

6-2. VS Gen-lock Mode [EXT (VS)]

1. Move cursor to SYNC and select INT.

2. Connect the coaxial cable for the com-

posite sync or composite B/W video

signal to the GEN-LOCK connector.

3. Confirm that INT changed to EXT (VS)

on the menu.

Note: The gen-lock input signal should

meet EIA RS-170 specifications

and should not contain jitter, such

as a VCR playback signal, as it could disturb synchronization.

4. After confirming that the cursor is on EXT (VS), press I. The phase adjustment menu

appears on the monitor screen.
