Review (August 2003) - B&K Precision
Video generators have come a long way from the good old days of NTSC products. The new breed of high-definition displays requires significantly higher scan rates and tri-level syncs. The need for high-definition capable video generators has also increased as more consumers hire ISF (Imaging Science Foundation) certified technicians to calibrate their displays and has become an important part of today's serious home theater enthusiast. Accurate color tracking and properly adjusted black and white levels produce the best picture possible. Video calibration requires a video generator capable of multiple scan rates and a variety of different reference patterns. B&K Precision has introduced the new affordable Model 1253 Multi-standard Video Pattern Generator to service this market. The Model 1253 is capable of generating 720p and 1080i high-definition timing as well as standard definition 480i and 480p video. Fourteen video patterns and twelve of the most popular video scan rates are preprogrammed into this video generator. Commonly used video patterns include SMPTE color bars, PLUGE, needle-pulse, staircase, multi-burst, cross hatch, focus and multi-level IRE windows. An overscan bounce test is also built into the 1253 for checking the high voltage stability of CRT-based displays. The unit is light and fairly small, measuring only 5.6" x 3.1 x 1.1" and operates from a standard 9 volt battery. The unit is even smart enough to warn the user when the battery level has dropped too low.
Three BNC connectors for component video (YPrPb) and the standard mini-DIN connector for the S-video connection are provided. The catch is the S-video signal really only contains the Y portion of the Y/C signals needed for true color reproduction. Therefore, the S-video output on the 1253 is monochrome. The Y output of the component signals can also be used to drive the composite input of the display under test when selecting NTSC, PAL or SECAM formats. However, this signal also lacks any color carrier information, so the image will always be black and white. The unit comes with a BNC to RCA adapter cable to accommodate the RCA jacks found on most consumer displays. In addition, a zippered case is provided to protect the video generator.
