Adjust the Chroma Gain Fine control (21) so that the chrominance signal levels of both color bar signals are equal. Chrominance signal 6) Adjust the horizontal phase of the camera as follows: • Set the switches and controls on the Special Effects Generator so that the split color bar picture is observed on the program monitor. Refer to the operating instructions accompanying the Special Effects Generator. Color bar of camera Color bar of special effects generator Note: The horizontal phase as well as the subcarrier phase explained in the next paragraph should be readjusted if the connections of coaxial cable length is changed in the system. Underscanned Monitor Match these edges o o Color bar of camera Color bar of special effects generator Connect an oscilloscope to the Program Output connector of the Special Effects Generator and check the horizontal blanking period of the Program Output signal. Adjust the Horizontal Phase control (14) on the RCU so that the phase of the Horizontal blanking of the color bar signal for the camera matches that of the Special Effects Generator. 27.0° 90° 180“ COARSE LSC PHASE-GEN-LOCK ■ LOCK Match these edges • The horizontal phase of the camera can be roughly adjusted by observing the split color bar picture on the underscanned program monitor after all switches and controls have been correctly set. Adjust the Horizontal Phase control (14) so that the starting edges of the white bar of the camera and Special Effects Generator roughly match each other. 7) Adjust the subcarrier phase of the camera as follows: • Set the switches and controls on the Special Effects Generator so that the split color bar picture is observed on the program monitor. Refer to the operating instructions accompanying the Special Effects Generator for details. • Adjust the Subcarrier Phase Coarse and Fine Controls (17) on the RCU so that the colors of the color bars from the camera are similar to the colors of the color bars generated by the Special Effects Generator. • For precise adjustment, the use of a vectorscope is recommended. In this case, supply the Program Output signal from the Special Effects Generator to the vectorscope. While observing the vectorscope, adjust the Subcarrier Phase Coarse and Fine Controls (17) on the RCU so that the phase of the color bars from the camera matches that of the bars generated by the Special Effects Generator. Reset the Color Bar/Camera Selection & shutter ON/OFF switch (3) on the RCU from the BAR to the CAMERA, OFF position. Set the black balance while referring to "WHITE BALANCE SETTING' on page 0. 10) Set the white balance while referring to "WHITE BALANCE SETTING* on page 9. 8) 9) -7- BLACK BALANCE SETTING t. Black Balance Correct setting of the black balance is required for producing correct colors, especially in low-light situations. Once the black balance has been correctly set, the setting is maintained in a special memory, until the next setting. The setting will not be lost, even though camera power is turned off. For best results, it is recommended that the black balance adjustment be carried out, however, if the camera has not been used for a long period of time. 2. Automatic Black Balance Setting • Set the Iris Control Selection switch on the zoom lens and the Lens Iris Control (9) on the Remote Control Unit (RCU) to the A (Auto) or REM (Remote) position, and AUTO position, respectively. Note: If you need to set the black balance while in the manual iris control mode, the incoming light should be blocked by setting the Filter Wheel to close position or capping the lens. • Set the Auto/Manual Selection switch (6) on the RCU to the ABC position and press the Auto Set switch (7) momentarily. The lens iris is closed, blocking incoming light, and the black balance is automatically set. When the black balance has been set, the lens iris returns to its previous position. The Auto Warning indicator (8) on the RCU blinks while the black balance is being set. The indicator goes out when the black balance has been set. If the Auto Warning indicator remain lit, the black balance adjustment should be carried out once more. 3. Manual Black Balance Setting • Manual adjustment of the black balance is possible by adjusting the Red Pedestal and Blue Pedestal controls (16) on the RCU. • Set the Auto/Manual Selection switch (6) on the RCU to the MN (Manual) position and close the lens iris by setting the Filter Wheel on the camera to the close position or capping the lens. • Observe the signal waveform of the video output signal on an oscilloscope or a waveform monitor. • Adjust the Red Pedestal and Blue Pedestal controls (16) on the RCU so that the carrier wave of the video output signal is at minimum. Minimize the carrier wave using the Red & Blue Pedestal controls. ir- • The overall pedestal level can be adjusted by the Total Pedestal control (13) on the RCU. Note: The black balance setting will be kept in the ...
