Preparation for first time use Battery Types Used The Model VP300 generator is supplied with four (4) internal size AA rechargeable Nickel Metal Hydride (NiMH) cells. These 1500 mA/H rated cells will operate the generator for about 8 hours on a full charge. They can normally be recharged about 1000 times before needing replacement. No other type of rechargeable battery can be used in the generator! You can use non-rechargeable alkaline AA cells with the generator, provided that you never use th

Pattern Description and Usage SMPTE Bar Pattern Description: The upper two-thirds of the pattern consists of seven equal-width vertical bars, with 75% white (gray) at left, followed by three primary and three seconday colors. Color bars are at 100% saturation with 75% amplitude. Just below these bars is a section of short bars containing the blues complement color for each of the large bars containing blue. Under those color bars containing no blue (yellow, green, and red), the short bar is blac

at black (7.5 IRE for NTSC, 0 IRE for other formats) and has a five-step gray scale positioned on it. The second rectangular zone from the center alternates between two light levels, black and slightly blacker than black (7.5/0 IRE for NTSC, 0/-4 IRE for other formats). The third rectangular zone from the center is fixed at a light level slightly whiter than black (10 IRE). The fourth, outer rectangular zone is fixed at black. The average picture level (APL) of this pattern is very low. Pattern

contrast/picture control is adjusted for a higher white level than the display device is capable of producing properly, one of two distortion effects will be observed; blooming or raster distortion. Blooming is especially prevalant in CRT displays and results in light from very bright pixels (phosphors) spilling over to adjacent pixels. This causes bright picture areas to become defocused and slightly larger than they should be. If a display blooms at high luminance levels, as the contrast contr

Pattern Description: Eleven equal-width horizontal bars step from 100 IRE white at the top of the pattern to black at the bottom (7.5 IRE for NTSC, 0 IRE for all other formats), forming a horizontal staircase. Pattern Usage: Useful for visually checking gray-scale tracking performance of a display, especially a projector with red and blue overdrive at the sides of the display, due to insufficient correction for CRT side-to-side placement (with green in the center). Poor gray-scale tracking perfo

overscan. An “X” marks the electrical center of the pattern. Pattern Usage: Used to check and adjust for the proper geometry of a display, including picture centering, size, trapezoid (keystone) correction, pincushion (bow) correction, and linearity. Horizontal and vertical centering controls should be adjusted to center the pattern on the display screen. The chevrons at each of the four edges make it particularly easy to see whether there is equal amount of overscan at the sides or at the top a

Window1, Window2 Pattern Description: Centered white window on black background. Luminance levels of Window1 and Window2 are independently adjustable from 100 IRE to 0 IRE in either 5 IRE or 1 IRE steps. Each window pattern includes pluge level bars at +4% and –4% to the left of the white window. Pattern Usage: Use the white window to measure chromaticity of a display device. This pattern is preferable to using a full field white raster since the window pattern more closely duplicates the averag

Color Bar Pattern Description: Seven equal-width vertical bars with 75% white (gray) at left, followed by three primary and three seconday colors. Color bars are at 100% saturation with 75% amplitude. Individual colors can be gated on or off (in the Gating menu) to view only the red, green, or blue components of the pattern. Pattern Usage: Use as an overall check of a display device’s capability of producing fully saturated primary and secondary colors. Especially helpful in detecting full or pa

Focus Pattern Description: Consists of capital letter “E”s and “M”s alternating across the screen. Sometimes refered to as a MEME pattern. The closely spaced elements of these letters makes it easy to judge the effects of focus adjustments. Pattern Usage: Used as a reference signal for viewing the effects of focus adjustments across the entire screen. Since it is difficult for CRT displays to achieve uniform focus across the entire screen, multiple focus adjustments and/or compromise settings of

Regulate Pattern Description: A single pixel white border surrounds an interior picture area which alternates between full white and full black. Pattern Usage: Checks the regulation of CRT high-voltage and deflection power supply circuits. The pattern alternately produces maximum and minimum CRT beam current. Ideally, these current extremes should not cause the picture size to change. This can be judged by placing a thumbnail next to one of the border lines to see the amount of displacement (avo

Pattern Description: Pattern is an all white raster with two centered three-step gray scales. The top gray scale steps are at 10%, 5%, and 0% while levels. The bottom gray scale steps are at 90%, 95%, and 100% while levels (from left to right). Pattern Usage: This pattern can be used to check a display device’s ability to hold proper black level at close to 100% APL. Check that you can see three separate levels of dark gray and black in the top gray scale. The pattern is primarily useful, howeve
