9.2. Measurement Procedure 9.2.1. Video Output Level TEST CONDITIONS Refer to “MEASUREMENT CONDITIONS” MEASURING SYSTEM System 1 PROCEDURE 1. Shoot the gray scale chart, and zoom WIDE or TELE to fit the chart to the monitor 2.
9.2.2. Color Reproduction TEST CONDITIONS Refer to “Measurement Conditions” MEASURING SYSTEM System 1 PROCEDURE: 1. Shoot the color bar chart and zoom WIDE or TELE to fit the chart to the monitor. 2. Measure the color amplitude and color phase on the vector scope of Red, Blue, and Yellow. (Before the above measurement, Adjust the burst amplitude and phase on the vectorscope so that the burst level becomes 100% and its phase becomes 180°.
9.2.4. Horizontal Resolution TEST CONDITIONS Refer to “Measurement Conditions” MEASURING SYSTEM System 1 PROCEDURE: 1. Shoot the resolution chart and zoom WIDE or TELE to fit the chart to the monitor. 2. Adjust the brightness and contrast of the B/W monitor so that each step of the gray scale portion of the chart can be observed. 3. Change the scan size of the monitor to under scan. 4. The reference arrows on the resolution chart are positioned at the edge of the under scanned picture. 5.
