Section 4 ♦ Operating the CMN-91 Each R, G, and B pixel is plotted using amplitude and phase. The amplitude is derived from the R, G, B component. The phase is derived from the Cb Cr information of the digital signal. The pixels can be plotted as a single color or as each component color (see Table 5-8 on page 72). Unlike the composite Gamut vector, which plots two points per pixel, the RGB Gamut vector plots three points. Also, signals with no color content are displayed on a separate bar graph labeled Mono. The RGB graticule is nearly identical to the composite graticule. The only differences are • Amplitudes are displayed in mV rather than IRE or UNITS. • The radials representing color vectors are 60° apart since they are displayed in a component color space. • Mono bar graph is for monochrome. NOTE: There is an alarm persistence of two seconds associated with any alarm indication. After an alarm has cleared, two seconds will pass before the gamut indicator returns to normal. Figure 4-23. Component (RGB) Gamut Vector Display Graticule Markings Table 4-7. Description of RGB Gamut Indicators Key Indicator Description 1 Lower Gamut Ring The lower gamut ring indicates the RGB Gamut alarm Lower limit. When the RGB Gamut alarm is enabled and the Lower limit is exceeded, the lower gamut ring turns red. 2 Upper Gamut Ring The upper gamut ring indicates the RGB Gamut alarm Upper limit. When the RGB Gamut alarm is enabled, and the Upper limit is exceeded, the upper gamut ring turns red. 3 Vector Excursion Mark The excursion marks help to visualize the minimum/maximum values of 100% color bars. 4 Mono Mono indicates the monochrome of the RGB signal. There is no alarm associated with Mono. 48 CMN-91 Series Installation and Operation Handbook Copyright © 2009, Harris Corporation
Section 4 ♦ Operating the CMN-91 Placing the Gamut Display in Line Select Mode Press the LINE button to enable monitoring of a single line of a video signal. This enables Line Select to monitor individual lines of the entire image. To view a line in Line Select mode: 1. Press the LINE button to place the selected Gamut display in Line Select mode. At the bottom of the display, the Line number and Odd or Even field appear, as shown in Figure 4-24. Figure 4-24. Establishing Line Select NOTE: In a Progressive (p) format, Odd and Even selections are not available. 2. Press the Up/Down arrow knob to alternate between the Odd and Even fields for interlaced formats. 3. Rotate the Up/Down arrow knob to select the line to be displayed. Setting Display Options Press and release the ZOOM button to cycle through the displays of the Composite or RGB gamut graticule: • Expand the center • Expand the upper-left quadrant • Expand the upper-right quadrant • Expand the lower-right quadrant • Expand the lower-left quadrant • Normal view Gamut Setup Menu Press and hold the GMT function button to access the Gamut Setup menu. For more information on the global Gamut Setup menu, see page 72. For descriptions of Gamut Setup menu selection options, see page 83.
