The A223802 has built-in 4 HDMI output ports supporting up to 8Kx4K@60Hz resolution (@4 ports) or 4Kx2k@60Hz (X4 ports) for single port output. Compared to the previous HDMI 1.4 version, it increases the overall image transmission efficiency and complies with the HDMI 2.0b version specification.

The ARC (Audio Return Channel) test supports 5.1 audio channels with a 192 KHz sample rate per channel and 16/20/24 bits per sample size. The A223802 can act as an ARC Receiver to receive the audio signal returned by the Transmitter through an HDMI cable to check if the ARC function of the DUT is normally activated.

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.

CEC (Consumer Electronics Control) is a feature of HDMI allowing users to control multiple connected devices through a remote controller. It solves the problem of requiring several remote controllers to control the corresponding devices. Using the CEC function to simulate the DUT, it is convenient for users to rapidly verify the device, providing a variety of verification applications.
