[. . . ] Automated Video Measurement Set VM5000 Features & Benefits Automates Test of Consumer HDTV Video Devices Automates VESA Compliance Test for PC Graphics Devices Fast, Accurate and Reliable Video Measurements Comprehensive Component Analog Video Signal Analysis SD, HDTV and RGBHV Component Analog Format Support Picture, Vector and Waveform Displays Companion Test Signal Packages Time Saving Test Utilities Pass-fail Limit Testing Automatic Report Generator Video Measurement Accessories Complete DPO Functionality The VM5000 automates video testing of consumer HDTV and PC graphics devices such as digital set-top boxes, multi-media PCs, graphics cards and video semiconductors. It addresses the needs of engineers developing and deploying the next generation of video devices for the digitally connected home. Unrivaled performance in terms of speed, accuracy and reliability has made the VM5000 the choice of industry leaders for design validation, quality control and ATE applications. Unlike conventional instruments, the VM5000 integrates acquisition hardware, optimized video measurement algorithms, test signal files and accessories into a cohesive test system solution. [. . . ] By selecting Picture mode, a full color picture display is rendered on screen from the connected sub-sampled and down converted signals to the available picture area and resolution. Pictures by default appear in an appropriate 16x9 or 4x3 aspect ratio; however, users can resize, move or minimize the window as needed. Picture mode incorporates a user-enabled bright line select feature to facilitate test configuration. Live or full motion video signals can also be viewed at vertical refresh rates of 1 to 2 fps. The Vector display, available with Option SD and HD, displays the waveform with targets for 75% or 100% color bars and accommodates either 601 or 709 colorimetry targets. Graticule targets and color space can be selected automatically or manually. Waveforms for all channels are simultaneously viewable in different colors, and display can be zoomed both vertically and temporally for detailed examination and analysis. Users can selectively expand the waveform to the full display size by minimizing the measurement application. Time-saving Test Utilities and Results Displays The VM5000 offers a powerful combination of test utilities and custom displays to make HDTV video test faster, more robust, more convenient and more accurate. These utilities supplement basic automated measurement capabilities to deliver performance and value unmatched by any other solution. Combined with the extended documentation utilities, these powerful automated measurement utilities and features ensure that the VM5000 meets the demands of all application areas. Research and Development, Quality Control and Production Test personnel can tailor the instrument settings to meet their particular needs for robust acquisition, speed or accuracy. By automating measurement functions, video professionals are ensured that automatic measurements are robust, accurate, repeatable and completely objective. Summary Test Results Display ­ For the ultimate in test progress and reporting, the VM5000 incorporates a summary test results display screen. This display enables operators to monitor test progress and acceptability of video signal parameters without having to delve into complicated individual test results. Each of the selected test parameters, measurement progress, pass or fail result per parameter and test errors, if any, are displayed. Upon completion, an overall green or red measurement result flag is displayed. Summary Test Results Display with Pass-fail Indication. Color Bar Relative Results Display with Limit Testing Enabled. Integrated Pass-fail Limit Testing ­ The VM5000 incorporates user-selectable pass-fail limit testing. Acceptability of individual parameters or an entire DUT can be assessed without browsing hundreds of individual numerical results. Suitable for use in stand-alone applications, there is a PF summary screen that shows the progress and PF result of individual measurements and an overall DUT PF result based on the selected parameters and user-selected limits. When PF limit testing is enabled, measurement results for failed parameters are displayed in an intuitive GREEN-RED numerical result for easy identification of unacceptable or nonconforming signal conditions. Video Measurement · www. tektronix. com/video 7 Automated Video Measurement Set VM5000 Reference and Limit Test Configuration Menu. Preloaded and User-definable Reference and Limit Files ­ Tektronix supplies a set of default reference and limit files for the supported video formats for "out of the box" test functionality. Option SD and HD have been preloaded with SMPTE/EIA standard reference values and Tektronix recommended tolerance limit files. Option VGA has been preloaded with VESA reference and tolerance limit values based on the applicable timing standards. The signal reference data boosts test productivity by minimizing the need to access separate standards or quality documents. [. . . ] Requires at least one of Option SD, HD or VGA with each new instrument ordered. Option HD ­ Test signal files (ATSC transport, TG700 DNL, Bitmap) on CD-ROM (020-2611-00); Sync pick-off accessory (012-1680-01), Option key enabling HD format support. Option SD ­ Test signal files on DVD (020-2610-00); Sync pick-off accessory (012-1680-01); Option key enabling SD format support. Option VGA ­ PC graphics test signal files on CD-ROM (020-2634-00), RGBHV Measurement Interface Unit (012-1685-00), VGA to 5x BNC cable, 6 in. [. . . ]
