The 22293-B Programmable Video Pattern Generator provides a total solution for multimedia tests that are applied in the industries of high frequency digital and analog displays such as LCM Monitor / LCD TV / PDP / Projector of today and in the future.

Large scale and high definition have become the trend as the development of video industry goes. The 22293-B designed with brand new architecture uses high performance CPU to carry the high speed/high density FPGA as Graphics Rendering Engine. It provides highly efficient system control as well as supports the up-to-date high resolution multimedia digital/video interface, HDMI V1.3, for the following features:  

Higher bandwidth and Color Deep : It supports 24, 30, 36 bit (RGB or YCbCr) and new color standard xvYCC to implement real natural color and high resolution image screen with larger color range.

CEC (Consumer Electronics Control) Function : It allows users to activate the HD device that equipped with multiple CEC functions via a remote controller. The 22293-B is able to set the CEC test parameters automatically or manually and support TX (transmission) / RX (reception) / MONITOR (monitoring) & FEATURE (user property) test modes. The built-in CEC test patterns give users easier and faster test judgment.

Lip Sync: Since the technology of digital signal process improves continuously, to have a high definition video presentation, there may have potential factors to cause delay when processing the video. HDMI 1.3 al lows CE devices to compensate the time difference automatically that can synchronize both video and audio to enhance viewer's feeling.

The 22293-B is able to provide Analog/Digital/TV signals concurrently:

For the analog signal RGB output, the pixel rate is up to 250MHz that meets the RS-343A standard, and it supports Y,Pb,Pr / Y,Cb,Cr / Y,R-Y,B-Y. The digital signal output is TMDS with pixel rate up to 330MHz and the test screen resolution supports beyond UXGA. Furthermore, to cope with higher frequency signal test, the 22293-B supports DVI Dual HDCP test for dual channel DVI test application.

As to the specification of TV output, the image and chrominance signals of the 22293-B meet the NTSC, PAL and SECAM standards. The output signals include CVBS compound signals, BNC and Y/C (Luminance/ Chrominance) separated signals as well as S-Video/SCART output connectors. Tests for special TV functions such as Closed Caption, V-chip and Teletext are also supported. In the meantime to fulfill the test application for multi-port output, the 22293-B has built-in 3 HDMI and 2 SCART ports to reduce a great deal of test time, so as to finish the tests in the fastest way possible.

As to operation, the 22293-B has equipped with a 3.5 inches multicolor display with graphic operation interface. Users can edit various timing parameters and patterns through the icons on the panel directly or using the VPG MASTER control software via the USB interface to do remote control manually or automatically. The comprehensive, rapid and easy to understand user interface can improve the test efficiency effectively. Following the rising market of new generation display the competition and demand for product quality are getting more and more sever. Under the consideration of quality and cost, the 22293-B Video Pattern Generator has built in the most complete multi-media test interfaces that can meet the requirements for various video tests in the industry. It is the best solution for the users in the field of RD, production and inspection.
