Chroma 22294-A is a programmable video pattern generator that equipped with various standard analog / digital signal output functions. The built-in high speed graphic engine is able to provide standard test signals and patterns for display devices with various resolutions to meet the requirements of multimedia display industries today and in the future for R&D and test applications.

The Video Pattern Generator suppor ts the up-to-date high resolution multimedia digital audio and video transmission interface HDMI V1.4b specification with the following features: 

Support up to 4K x 2K ultra high resolution

For digital interface, the HDMI supports 300MHz and DVI supports up to 330MHz (Dual link). For analog interface, the signal supports up to 300MHz. The high bandwidth signal output capability supports the testing for the newest generation of 4K x 2K ultra high resolution displays.

3D standard format signal output

The 3D format defined by HDMI specification is fully supported with abundant 3D test patterns, and provided for the user to download customized 3D patterns (splitting left/right images in Bitmap file format).

Fully support HDMI defined functions

The 22294-A is equipped with HEAC (Ethernet / Audio Return Channel) / Lipsync / HDCP / CEC / EDID functions and supports 24 / 30 / 36 bit color depth (RGB or YCbCr) and newest generation of color standard xvYCC / sYCC601/ Adobe RGB / Adobe YCC601.

Multi-signal port for simultaneous output

The 22294-A has 4 HDMI output ports that can provide multi-signal output simultaneously to meet the test applications for multi-port displays nowadays.

The RGB (BNC / D-Sub) and component (YPbPr / D-Terminal) signals provided by 22294-A are able to output all kinds of standard signal formats to test the displays with traditional analog interface. For digital DVI output signal, the pixel rate is up to 330MHz and supports dual channels HDCP which is most applicable for high resolution display testing.

For TV signals, the 22294-A is able to output the signals that comply with NTSC, PAL and SECAM specifications, also to support CVBS and Y/C separation signal formats for BNC / S-Video / SCART output ports. Special TV function tests such as Closed Caption, V-chip and Teletext are also supported.

Chroma 22294-A has full color graphic interface and super large capacity of storage memory with lots of special test patterns built-in such as xvYCC, HDCP, E-EDID, Deep color, CEC, Lipsync and high-definition test images defined by China to give the user an easy way to judge the test result and save the time for production improvement as well as to achieve cost effective control. In addition to the panel editing of standalone device, remote control can be applied also the application software VPG Master can be utilized to edit various test programs and parameters. Its easy-to-use interface and complete test functions are most suitable for the applications of R&D, production tests and quality assurance in all video and associate industries.
