A223813 supports switching between six types of DisplayPort and USB-C output. Both the DisplayPort and USB-C ports support up to 20 Gbps output. Users can switch between different interface outputs without physically disconnecting cables, reducing time of test as well as wear and tear on cables, thus enhancing overall testing efficiency.

MST (Multi-Stream Transport) allows for image output to multiple displays in a daisy-chain setup. This greatly simplifies the cable configuration, as the DisplayPort signal source only requires one output port. Chroma A223813 supports MST transmission for a maximum of 4 streams at a bandwidth of up to 80 Gbps.

A223813 has built-in Compliance Test Patterns such as OFF / D10.2 / PRBS7 / PLTPAT / CP2520 / TPS4 to facilitate users to perform initial verification of CTS Link Training.

The A223813 can be set to automatic, manual, or fast Training mode. It supports configuration of Lane Count, Swing Level, and Pre-Emphasis, allowing for the simulation of non-standard signal outputs to conduct tests related to the DUT's peak values.

• Lane Count：1 / 2 / 4 lanes
• Swing Level：400 / 600 / 800 / 1200 mV
• Pre-Emphasis：0 / 3.5 / 6 / 9.5 dB

A223813 supports a variety of color gamut outputs. In addition to the basic color spaces, it also supports Wide Color Gamuts such as RGB, ITU-601, ITU-709, xvYCC-601, BT.2020-YC, BT.2020-RGB, and DCI-P3 RGB. Users can set up pixel encoding formats such as YCbCr 4:4:4, 4:2:2, 4:2:0, and select color depths of 6, 8, 10, 12, or 16 bits for a wider color range to achieve natural and high-resolution image displays.

During testing, Chroma A223813 can simultaneously display relevant test results of two separate DisplayPort ports on the DUT’s screen, supported by two modes: Pattern Mode and Link Code Mode. In Pattern Mode, HDCP is automatically executed, and the results are displayed on the screen. In Link Code Mode, HDCP process steps are executed one at a time. If the handshake process fails, users can intuitively assess the issues and potential causes.

The module features a built-in FPGA (Field Programmable Gate Array) that supports an ultra-fast 16K graphics processing unit, enabling rapid processing of large amounts of image data. This significantly enhances graphics and data transfer speed, with image switching times as fast as 200 ms at a 16K resolution, ensuring efficient data retrieval from the built-in Solid State Drive (SSD). This improves testing efficiency and covers product testing at various resolutions, ultimately saving production costs.

The included VPG Master software offers DSC image format compression functionality, supporting the loading of external test image files (bmp, jpg, tiff) for storage of up to 100 images. Users can customize image resolution, refresh rate, color space, horizontal or vertical cropping, and compression ratio. They can also mark the images with text strings of up to 31 characters with customizable fonts, sizes, colors, and positions. These customized settings can be directly downloaded to the Chroma 2238, making it easier for users to identify whether DSC (Display Stream Compression) has been activated or deactivated.

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.

High conductivity beryllium copper improves the conductivity between components and reduces electromagnetic radiation leakage interfering with the DUT, in compliance with CE/EMC (Electromagnetic Compatibility) standards.
