A223802具有内置的4 HDMI输出端口，可为单个端口输出提供多达8KX4K@60Hz分辨率（@4端口）或4KX2K@60Hz（X4端口）。与以前的HDMI 1.4版本相比，它提高了整体图像传输效率并符合HDMI 2.0B版本规范。
A223802带有8个独立音频测试信号发生器（FL，FR，RL，RR，FC，LFE，RLC，RRC），能够启用/禁用/禁用/禁用/禁用卷，音调，音调，音调频率，样品率，样品位和扫描为用户提供多达48种用于测试的组合。
ARC（音频返回通道）测试支持5.1音频通道，每个通道的样本率为192 kHz，每样本量16/20/24位。A223802可以充当电弧接收器，以接收发射器通过HDMI电缆返回的音频信号，以检查DUT的ARC函数是否通常被激活。
HDCP(High-Bandwidth Digital Content Protection) is a protection mechanism used to ensure that digitized video and audio data will not be illegally copied during transmission. The A223802 supports HDCP 2.2 and 1.4 versions which allow users to switch in between, also check if the HDCP is normally activated and the related handshake information from the output screen with the built-in dedicated HDCP test images.
With the support of HDR (High Dynamic Range) contrast image output, the brightness range and color level are greatly improved to near the real image seen by the human eyes. The test items of HDR function are aimed at brightness, contrast, color, sharpness and dynamic images, etc. primarily the factors that affect the visual perception of consumers. Users can freely adjust the HDR metadata to perform the HDR function related tests. The A223802 that supports HDR10 and HLG has built-in test patterns of various HDR standards, such as grayscale, color bars, window patterns, etc., for use as desired.
SCDC (Status and Control Data Channel) is a new communication function of HDMI 2.0 that can exchange status and control information between the signal source and the sink. The A223802 can display the important signal indicators such as TMDS Scrambler Status and Channel Error Count in SCDC in real-time through the screen output, which is convenient for users to interpret during the test.
In addition to the basic color gamut, the A223802 also supports a wide color gamut including RGB / ITU-601 / ITU-709 / xvYCC-601 / xvYCC-709 / sYCC-601 / Adobe YCC-601 / Adobe RGB / BT.2020-YC / DCI-P3 RGB / BT.2020-RGB. It can set YCbCr 4:4:4, 4:2:2, 4:2:0 Pixel encoding format and 24 / 30 / 36 bits color depth, providing a wider color range to achieve true natural color and high-resolution images, which satisfies the high-standard 8K display inspection requirements of today.
EDID (Extended Display Identification Data) is a VESA-defined data standard for identifying DDC displays. The A223802 directly reads/compares/writes in the EDID register inside the display through I2C, which includes the suppliers’ information, image size, color setting, frequency range, etc. In the meantime, users can use software to edit EDID and control functions through an external PC to display the complete analysis results.
CEC（消费电子控制）是HDMI的一个功能，允许用户通过遥控器控制多个连接的设备。它解决了要求多个遥控器控制相应设备的问题。使用CEC函数模拟DUT，用户可以快速验证设备，并提供各种验证应用程序。
Chroma 2238视频模式生成器将完整的可执行程序与时间，测试模式和音频集成在一起，可以根据测试需求自由配置。该设备不仅携带了2000个定时模式和5000张图像，而且用户还可以添加自己的测试模式以满足各种测试规格。
The A223802 is a reliable and impartial signal module that passed the inspection of international test equipment and rigorous signal integration verification test, providing excellent functions to fulfill customers' requirements.
高电导率铍铜改善了组件之间的电导率，并减少了符合CE/EMC（电磁兼容性）标准的电磁辐射泄漏干扰DUT的电导率。
Licensed by The Institute of Image Information and Television Engineers in Japan, a variety of 8K Ultra-High Definition wide color gamut test patterns are available. (optional)
