Television and display specifications are rapidly evolving towards ultra-high resolutions and superior color presentation. New 2K, 4K, and even 8K resolution displays are introduced to the market on a daily basis, supporting a range of signal interfaces such as HDMI, DisplayPort, USB-C, and SDI, and used in a host of applications spanning the film, medical, gaming, and automotive industries. Manufacturers keep pushing the envelope to meet consumers' need for ever-more compelling visual experiences. However, with millions of pixels on the screen and the need to support various video signal specifications and functions, defects are bound to arise during the production process. Swiftly detecting and addressing such defects has become a critical concern for manufacturers. The Chroma 2238 Video Pattern Generator is a display evaluation expert, and can be paired with the Chroma 71241 High Accuracy Universal Measuring Probe for a complete display test solution poised to bring your production efficiency to the next level.

Wide Array of Test Interface Combinations

Chroma 2238 can be equipped with any of 12 high-performance, interchangeable signal modules, including HDMI, DisplayPort, USB-C, 12G-SDI, Analog, and DVI. Simultaneous output through up to 4 different signal modules can be achieved with the 2238's Multi-Out function. Each signal module has an independent high-speed graphics engine capable of simultaneously outputting different resolutions (timing) and test patterns, with a switching time for ultra-high-resolution images of only 200 mS (at 8K). The instrument also comes with a library of 34 3D test graphics. Users can freely choose the most suitable configuration according to their test applications.
