 信號發(fā)生器K-8257 & K-8257R (Read type) offers a total video signal test solution for Smart Panel and Multimedia video signal test signals. This generator has standard video regulation and standard TV signal outputs NTSC/PAL/SECAM/SDTV/HDTV/etext/V-chip/Closed Caption also fit into the multimedia display application for LCD TV, PDP TV, projector industries all over the world. 
The Analog RGB (8MHz~250MHz) output is possible to support up graphic display to 4096 X 2048. Digital output (DVI-single link: 25~165MHz, Dual link: 25~260MHz) is up to UXGA (1600X1200). The TV output specifications for image and chromaticity of K-8257 & K-8257R meet the NTSC and PAL standards. For output interface, the BNC connector provides CVBS composite signal and the S-Video connector provides Y/C. HDMI (High Definition Multimedia Interface) is all digital, audio/video interface standard. Especially, K-8257 & K-8257R is standard support HDMI V1.0~V1.1 function, enhanced, or high definition video, plus multi-channel digital audio on a single cable. HDCP (High0bandwidth Digital Content Protection) is a specification to protect digital entertainment content across the HDMI and DVI interfaces. The HDCP function supports production Key encryption and is included on both HDMI and DVI outputs. This model has etext function, closed caption and V-chip. etext is generic name for a system of information broadcast as pages of text alongside the evision signal for PAL Systems. The Closed caption and V-chip for TV (NTSC). The rating MPAA for movie and USA TV are available for selection. Closed Captions are captions that are hidden in the video signal. The V-chip is a standard for placing program rating information on a evision program. So that parents can be choose to filter what program their children can watch.
According to rising market of multi-media display the competition and demand for product quality are getting more and more severe as consumers often request and search for higher pixels with less bad dots as well as low cost video display products before purchasing. Under this circumstance, the K-8257 & K-8257R are Programmable Video Signal Generator with high resolution test quality and Multi-output can meet the multimedia display pplications at present, and the features described above make the Video Pattern Generator an indispensable testing tool for the R&D engineers and production manufacturers.
