||||
|
|
|
|
||
|
Anamorphic 4:3 – use to check the accuracy of a display device’s anamorphic stretch feature. |
|
Checker – use to check the regulation of CRT video drive power supply circuits. |
||
|
|
|
|
||
|
Color Bar – use as an overall check of a display device’s capability to produce fully saturated primary and secondary colors. |
|
Converge – use to color converge a display throughout the entire picture area. |
||
|
|
|
|
||
|
Crosshatch 4:3 (16:9 also included) – use to check and adjust the convergence of red, green and blue pictures. |
|
DecodAdj – use to adjust a display’s color decoder/matrix circuit for most accurate color reproduction. |
||
|
|
|
|
||
|
DecodChk – use to check the color decoder performance to determine if the decoder over-emphasizes red or green colors. |
|
Focus – use to view the effects of focus adjustments across the entire screen. |
||
|
|
|
|
||
|
HiLoTrk – use to set the contrast and brightness controls on fixed-pixel (non-CRT) displays. |
|
Horizontal Staircase (H Stair) – use to visually check grayscale tracking performance of a rear projection display. |
||
|
|
|
|
||
|
Linearity – use for deflection linearity testing and alignment. |
|
Multiburst – use to check a display’s ability to produce sharply defined stripes, at equal brightness, up to the format’s full resolution. |
||
|
|
|
|
||
|
Needle – use to detect whether scan velocity modulation (SVM) is enabled on a display device. |
|
Overscan (16:9 also included) – use to check and adjust for the proper geometry of a display, including picture centering, size, trapezoid (keystone) correction, pincushion (bow) correction, and linearity. |
||
|
|
|
|
||
|
Pluge – use to set the picture black level and check the DC restoration (black clamping) performance of a display device. |
|
Ramp – use to check the digitizing linearity of video signal processors. |
||
|
|
|
|
||
|
Raster – use to check color purity and display chrominance uniformity. |
|
Regulate – use to check the regulation of CRT high-voltage and deflection power supply circuits. |
||
|
|
|
|
||
|
Sharpness – use to align display sharpness, picture, aperture, and scan-velocity modulation (SVM) adjustments. |
|
SMPTE Bar – use to adjust color and hue through a blue filter with composite, S-video, or YPbPr signal inputs. |
||
|
|
|
|
||
|
Staircase – use to visually check grayscale tracking performance of a display. |
|
Window1 – use the white window at a high IRE to calibrate display drive chromaticity. |
||
|
|
|
|
||
|
Window2 – use the white window at a low IRE to calibrate display cutoff chromaticity. |
|
VP401/403 Optional HDCP test – works with any pattern to test (copy protect) HDCP compatibility. |
