Chroma A223810 USB-C Signal Module supports myriad functions of the USB-C signal interface. In addition to basic data transmission (pass-through), USB Power Delivery, and DisplayPort Alternate Mode functionality testing, it also provides a status monitor function allowing users to confirm the current communication role and status and various parameters. In addition, the programmable automatic test functions enables users to tailor test programs according to each UUT's specific requirements, and start testing with just a single push on the button.
DisplayPort Alternate Mode Testing
The American Video Electronics Standards Association (VESA) officially supports DisplayPort Alternate Mode (DP Alt Mode) through the USB Type-C standard. With DP Alt Mode, the USB-C interface can be used to provide complete audio and video output. The USB-C Signal Module supports DP 1.4 Alt Mode video transmission with up to High Bit Rate 3 (HBR3) 8.1Gbps bandwidth transmission and provides 8K (7680x4320) @30Hz display testing. A223810 also has High-Bandwidth Digital Content Protection (HDCP) 1.3, 2.2 and 2.3 test functions.
Power Delivery 3.0 Testing
The USB-C Power Delivery (PD) 3.0 protocol supports up to 100W (20V/5A) power output and the programmable power supply (PPS) protocol allows precise adjustment of voltage and current and meets the actual application requirements. Compatible with various PD 3.0 fast charging protocols, the signal module offers fast role swap (FRS) functionality between power supply and power receiving modes.
USB Pass-Through Testing
Chroma A223810 supports both USB 3.2 Gen 2 specifications and 10Gbps/5Gbps/480Mbps transfer speed. The USB-C simulator measures data including voltage, current, USB version, and USB read/write file transfer rate.
Programmable Automated Testing
For USB-C testing, the Chroma A223810 module supports programmable automated test functions. Users can edit the test program according to the specifications of the test object. Test items cover DP Alt Mode image output, Power Delivery VBus/CC Pin, Power Data Object (PDO) setting parameter comparison, pass-through rate, software based cable flip, and other test items required by various USB-C products, even including simultaneous testing of multiple modules. The test results can be confirmed directly through the output screen, or read through communication commands.
Multi-Stream Transport Test Function
Multi-Stream Transport (MST) can output images by cascading multiple sets of displays. Whereas other signal interfaces require multiscreen output in parallel, the MST function allows the signal source to drive multiple displays with only one output port. Chroma A223810 greatly simplifies the configuration of cables.
