Chroma 2403 programmable video pattern generator is the perfect instrument for digital video signal interface testing. It provides users with a high performance-low cost test solution. 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 supports the up-todate high resolution multimedia digital audio and video transmission inter face HDMI and DisplayPort specification with the following features:

Supports 4K x 2K 60Hz
2403 is built-in with a high speed graphic engine. The output signal can reach up to 600MHz. It supports UHD(Ultra High Definition) 4K x 2K@60Hz ultra high resolution displays testing.

Modulized Signal Interface Design
The modulized design output interface has 2 signal module terminals for users to choose from based on their testing needs. The modules support multi-signal terminal synchronized output capability which meet the multi-input terminals displays testing.

HDMI 2.0 Testing Function (HDMI module)
Supports HDMI 2.0 standard 6Gbps TMDS signal output (TMDS rate) and HDCP1.4 / 2.2 Supports 24 / 30 / 36 bits color depth (RGB / YCbCr) and HDMI 2.0 standard YCbCr 4:2:0 sampling format output and at the same time provides high resolution color standard ITU-R BT2020 and HDCP 2.2 / ARC (Audio Return Channel) / CEC / EDID testing functions.

DisplayPort 1.2a Testing Function (DP module)
Supports DisplayPort 1.2 standard HBR2(High Bit Rate 2, 5.4Gbps) bandwidth transmission up to 4K x 2K 60Hz . Also supports audio transmission and 3D/EDID testing functions.

Hot Key Function
Default or user-defined testing program can help to increase manufacturing efficiency. Chroma 2403 is built-in with abundant timing and pattern, including standard static, motion and scrolling pattern. It supports the testing of the displays’ performance.The modulized signal interface design can be flexibly choose from based on testing application. The VPG Master supports programmable timing, pattern and program. Its user-friendly interface is suitable for R&D, production and QA verification.
