Page 4: Battery Information And Installation
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. -

Page 8: Pattern Description And Usage
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. - Page 9 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).
- Page 10 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.
- Page 11 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).
- Page 12 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.
- Page 13 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.
- Page 14 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.
- Page 15 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.
- Page 16 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.
- Page 17 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.

Page 21: Colorpro Sub-Menu
Color Pro Sub-Menu ColorPro Sub-Menu Uses the ColorPro probe to measure the chromaticity and luminance (brightness) of the test CRT display. The ColorPro probe connects directly to the serial port on the generator. Chromaticity is shown as C.I.E. x, y coordinates and the luminance (Y) can be shown in units of either Foot-Lamberts or nits. -

Learn Formats Function and Options Menu Learn Formats Function Reads back EDID format data from a VESA® DDC-compliant display connected to the generator's VGA output. A list of standard VESA video formats supported by the monitor is extracted from the EDID data and compared against all of the VESA formats in the generator's built-in library. -

The VP300 Pluge pattern, shown in Figure 1, provides a unique black level alignment signal that was designed for easily adjusting the brightness control for proper black level. -

TV is calibrated. When the Pluge pattern is selected with the NTSC format, the VP300 automatically displays an NTSC pluge pattern with a 7.5 IRE black setup level. When an HDTV format is selected, the VP300 displays an HDTV pluge pattern, without black setup. -
Page 25: Contrast Control
Fig. 2 – The Needle pattern is used to properly adjust the television sharpness control. While adjusting the sharpness control, watch the left and right edges of the needle pulse lines. If the sharpness is set too high, a faint duplicate line will be seen beside the original line. This ghosting affect is unwanted picture distortion. -
Page 26: Color Control
Fig 3: The Needle Pulse pattern is used to adjust the television contrast control for proper white level. The VP300 Needle Pulse pattern works also very well for adjusting the contrast control for maximum light level while minimizing raster distortion or blooming. Adjust the contrast control until the top white bar is the same width as the four gray bars under it. -

bars. These bars should appear very colorful without any signs of blooming into the adjacent bars. Large Outside Bar Small Center Bar Fig 4: The SMPTE bar pattern blue and white bars are used to calibrate the television color control. Tint Control Adjust the tint control by comparing the intensity of the cyan and magenta color bars through a blue filter. - Page 28 Cyan Bar Small Magenta Fig 5: The SMPTE bar pattern cyan and magenta bars are used to calibrate the television tint control. Remember that the user controls should be calibrated with the room lighting adjusted to the preferred level for movie viewing. These controls should also be the final adjustments that are made to the TV.

(use the Needle pattern). Fig. 1 - VP300 Pluge pattern 3. Select the VP300 Window1 pattern and adjust the pattern level for a low IRE level to produce approximately 1-2 Ft-Lamberts of luminance in the center of the white window, as measured with the color analyzer. - Page 30 5. Select the VP300 Window2 pattern and adjust the pattern level for 80-100 IRE. Most direct- view displays will track well up to 100 IRE, whereas many projection displays produce a better compromise tracking when adjusted at a lower IRE level.
