A223804USB-C signal module can support various required testing functions for USB-C interface not only basic Data transmission (Pass-Thru), USB PD (Power Delivery) functional test, DisplayPort Alternate Mode functional test but provide Status Monitor for users to check the characters and parameters of current status of equipment's communication, and support programmable auto inspected function simultaneously for users to edit a Test Program to achieve automatic testing with one button.

Video Electronics Standards Association VESA announced DisplayPort Alternate Mode (Alt Mode) will be supported via USB Type-C. By DisplayPort Alt Mode，which utilizes USB Type-C interface and connection cable to provide a complete video output. A223804 USB-C signal module supports DisplayPort 1.3 Alt Mode and the bandwidth transmission can up to HBR2(High Bit Rate 2, 5.4Gbps), and supports 4K(4096x2160)@60Hz for video testing. It is also equipped with HDCP (High-Bandwidth Digital Content Protection) 1.4 and 2.2 testing function.

In USB data transmission (Pass-Through), USB-C supports the latest USB3.1 standard among USB 3.1 Gen1 which is compatible for the main third revised version of Universal Serial Bus (USB). Compare to 480Mb/s half-duplex USB 2.0, USB 3.1 Gen1 is capable for 5Gb/s full-duplex for writing and reading simultaneously which is ten times transmission improvement. A223804 supports USB Pass-Thru testing function for user not only focusing on determining data version of the interface, but through real transferred document to do actual rating test to ensure the rate of the product is compliance with the standard requirement.

笔记本电脑和手机的充电接口差异很大，不同品牌和型号之间的充电器大多不兼容。因此，USB-IF协会促进了USB功率传递电源传输协议，该协议最近变得越来越受欢迎，用于支持USB PD充电设备，包括手机，数码相机，移动设备，外部存放设备，外部存放，笔记本电脑和监视器，允许充电，数据传输，数据传输和视频播放都将由一根电缆支撑。

在PD 2.0标准中，功率规范的定义最多为100W（20V/5A）。为了满足此要求，外部动力单元旨在支持A223804 USB-C信号模块，以支持高达100W的电源测试。外部电源单元可调节，以在功率角色之间切换，以匹配正在测试的单元的不同电压和当前规格。

The A223804 signal module supports programmable automated test function for users to edit the USB-C Test Program according to the specs of the unit under test. Test items including DP Alt Mode video output, Power Delivery VBUS / CC Pin testing, PDO setting parameter comparison, Pass-Through speed testing, cable flip and other required USB-C testing. The test results are directly shown on the monitor, or could be retrieve by commutation commands. Users will be benefited by uploading the test results to the SAP system from the test-result retrieving function.
