It operates at very high temperatures.
Chapter 7—Glossary ® Copy Source Used to copy Geometry, Convergence, Shading, ILA Settings and Adjustment data to another of the 20 source files. Cold Mirror Mirror that passes infrared light so that its reflection contains only "cold' light that does not transmit appreciable heat. As a result of infrared heat radiation, "cold" mirrors can get quite hot. Composite Video Means of transmission sending the complete video signal consisting of chrominance, luminance and the sync signals.
Chapter 7—Glossary Hertz (Hz) The standard unit of frequency. One Hz is equal to one cycle per second. A Kilohertz (KHz) is 1,000 cycles per second and a Megahertz (MHz) is 1,000,000 cycles per second. H-Grid Test pattern of rows of H's on screen. Used as a focusing aid. Highlighted Channel The channel that has been selected by scrolling through the channels list with the arrow keys or selected by pressing a channel number but has not yet been made active by pressing Enter.
Chapter 7—Glossary Linearity Adjustment Corrects for improper horizontal and vertical grid spacing on an image. With distorted linearity, lines in the grid are spaced closer together on one side of the image and farther apart on the other. The linearity adjustment is performed on green only and affects RGB. Luminance Abbreviated as "Y." The portion of the signal that contains the black and white information, which affects brightness.
Chapter 7—Glossary Raster The area illuminated by the scan lines on a CRT. Resolution The degree of sharpness of a displayed or printed character or image; the amount of detail in a picture. On a display screen, resolution is expressed as the number of horizontal dots (columns) by the number of vertical lines (rows). For example, a 680 x 400 resolution means 680 dots across each of 400 lines.
Chapter 7—Glossary Sensitivity (White) Adjustment for decreasing brightness on the bright areas of the screen. Used with Threshold adjustment to obtain optimal projected image. Sharpness Apparent image resolution. High sharpness may be the result of high resolution, or it might be an optical illusion caused by image enhancement or by visible edges in a display, such as the vertical stripes of an aperture grille CRT. Size Adjustment Fits the size of the projected image to the screen size.
Chapter 7—Glossary Vertical Synchronization Frequency The number of times per second a frame is transmitted to a video display screen. Xenon Arc Lamp See Arc Lamp. X-hatch Test Pattern consisting of white horizontal and vertical grid lines. Used for a number of geometry adjustments.
