Chroma A223801 Signal Module DisplayPort 1.4 supports 8K UHD (Ultra High Definition) image output, a dual-port maximum output resolution of 8Kx4K@60Hz and a single-port maximum output resolution of 8Kx4K@30Hz, in line with today's high-specification 8K image testing needs.

MST (Multi-Stream Transport) allows multiple displays to be connected to a single DP port, greatly simplifying the wiring configuration. The A223801 supports MST transmission specifications for simultaneous multi-screen output (4 Stream max or 8K 30Hz) up to 8.1Gbps.

HDCP (High-Bandwidth Digital Content Protection) prevents illegal copying of data as it is transmitted through the interface. The A223801 supports HDCP versions 2.3, 2.2 and 1.3 and allows the user to freely switch between the three versions. The built-in dedicated HDCP image test function can be output directly on the screen of the DUT, enabling users to instantly view related HDCP handshaking information.

Chroma A223801 supports a variety of gamut outputs. In addition to the basic gamut space, it also supports wide color gamut color space, including RGB, ITU-R BT.601, ITU-R BT.709, ITU-R BT.2020, DCI-P3. YCbCr 4:4:4, 4:2:2 Pixel encoding Mode and 6 / 8 / 10 / 12 bits color depth can all be set up to provide a wider color range and achieve true natural color and high-resolution images, in line with today's high-specification 8K image testing needs.

The DPCD (DisplayPort Configuration Data) acts as the main communication channel between the source and sink of the DisplayPort interface. By reading the DPCD register of the sink device, Chroma A223801 can display the transmission channel and rate supported by the sink device and carry out related tests by outputting the corresponding standard signal.

The VPG Master software enables compression of images into the DSC format. 37 built-in image files are included, and the module supports storage of up to 100 custom test pattern files (bmp, jpg, tiff). The software supports editing of image resolution, refresh rate, color space and compression rate, horizontal and vertical cutting, as well as other functions. Users can mark the image file with custom text strings of up to 31 characters with editable font, size, color and position, and download it directly to the Chroma 2238 device, enabling them to quickly determine the DSC's on/off state. (Optional)

The built-in resolution test chart can accurately indicate the correct scale according to different Timings. In addition to geometric shapes and aspect ratio tests (4:3, 16:9), other composite test patterns such as Color Bar and Grayscale are also included. With these test patterns, users can easily determine the display's imaging quality, which is especially useful for R&D, production and QA purposes.
