Features

●Variable 10-Step Staircase Generator Making For Easy Adjustment of the Gamma-Corrector Circuit of LCD Displays With both CRT and LED, the display brightness is not linearly proportional with the input signal but there is a curve for each type of display. Since the current video signal has been corrected for the curve of CRT, the color hue may be altered slightly if it is displayed on a LCD without correction. To prevent this, a very complicated adjustment using color bar signals or staircase signals with equal level intervals has been required for the gamma corrector- circuit of LCD displays. However, the CG-950 series incorporates a variable 10-step staircase signal generator which can simulate the curves. By applying a staircase signal with simulated curve, the output from the correction circuit of LCD displays can be made linear, facilitating the adjustment and reducing the adjustment process as well. The variable 10-step staircase generator can be preset to output up to 5 kinds of staircase signals. ●RGB Output and Y/C Separate Outputs Provided as Standard In Addition to Composite Video Output In addition to the composite video output for video equipment and a large variety of monitor equipment, an RGB output and Y/C separate outputs are provided as standard. An RF output can also be added optionally. ●Burst Signal on/OFF with Any Pattern To facilitate checking of the color killer circuitry, the burst signal on/OFF function can be used with all patterns. ●Selection of 9 Raster Patterns The raster patterns for use in the purity adjustment allow selection of intermediate colors (yellow, cyan, magenta) by combining R, G and B. As a result, 9 kinds of outputs including 100% white, 75% white, yellow, cyan, green, magenta, red, blue and black are available. The luminance and chrominance signals can additionally be switched on/OFF. ●Two Color Bar Patterns Split color bars (SMPTE) and full-field color bars are built in. The full-field color bars are available in 8 colors including black (100% white, 75% white, yellow, cyan, green, magenta, red, blur or black). In addition to the luminance and chrominance on/OFF switching, R, G and B can also be switched on/OFF independently. ●Setup 0% While conventional NTSC equipment used 7.5% setup level, a 0% setup level which is becoming the new mainstream is provided. ●EEPROM Memory The panel setups and the 10-step staircase setups are stored in EEPROM so that they will not be cleared even after the power is turned off. As the EEPROM does not need a battery for back-up, there is no need to worry about battery exhaustion. ●Composite Sync and Vertical Sync Outputs Provided as Standard The sync signal output can be switched to the composite sync and vertical sync, which is convenient for waveform observation on an oscilloscope. ●Example of Modified Patterns ●Horizontal color bars.●10-Step MOD. ●Oblique color bars. ●Circle .●Checkers.●Center-cross.●Scroll.* Please consult us for the modification costs. ●SPECIFICATIONS SPECIFICATIONS Patterns Cross-hatch 20 (V) ×16 (H)? white on black background? dot on the center? corner marker on the top left of screen Dot 20(V) ×16(H)? white on black background? corner marker on the top left of screen.
