UCD-240 • USB-C 4K Video Generator and Analyzer for Production Testing



UCD-240 is a cost-effective and flexible Test Automation tool for testing USB Type-C products in the production line environment. UCD-240 is a fully-featured Test Automation tool supporting DP Alt Mode, 4K@60Hz and NI TestStand. UCD-240 is easy-to-use and its test coverage includes all essential features of the USB-C interface.

UCD-340 test tool is used to configure test parameters for the automated tests used with UCD-240. UCD-340 is used with easy-to-use UCD Console UI to configure the test parameters. Only one UCD-340 unit is needed to configure tests for all UCD-240 devices.

The video below shows how you can set up, configure and run automated tests on USB Type-C smartphone straight from the command-line:

Platform for Test Automation

Cost-Effective and Flexible Solution for Automated Production Line Testing

UCD-240 is an automated test solution designed specifically for testing USB-C products in the production line environment. UCD-240 features an efficient and effortless way of USB Type-C sinks and sources.

The provided software enables user access to the vital test parameters and configured tests can be easily run from the command-line. UCD-240 is also fully compatible with third-party test management software e.g. NI TestStand. Unigraf’s Test System Interface enables easy integration of automated tests into existing test systems.

Complete Set for Automated Testing

UCD-240 comes as a plug & play package ready for automated tests. The delivery content includes UCD-240 HW Test Tool, All necessary TSI Software with licenses, Electrical Testing cable supporting automatic CC line flip and a USB 3.0 flash drive with pre-stored sequence files.


Three Options for Test Automation

Run tests with UCD Console and Command-Line

UCD Console GUI, delivered with each UCD-240 device, is used for specifying all test parameters used in the automated tests. You can easily select and modify all necessary test parameters according to your DUT needs. After the tests have been configured and stored in a known location, desired tests can be run straight from the command-line. You simply need to press enter and you will see if the selected tests pass or fail.

Run Automated Tests with Third-Party Test Management Software

UCD-240 is also compatible with third party Test Management Software e.g. NI TestStand. You can create your own tests or use the tests available to run automated tests with third party Test Management Software.

Unigraf’s Test System Interface (TSI)

Unigraf’s Software Development Kit (SDK) for test automation is called Test System Interface (TSI). UCD-240 can be used with TSI. TSI is a hardware-independent, high-level Software API (Software Application Interface). It offers compact and short cycle time test routines with which the functionality of most common display interfaces can be verified.

The use of TSI and the Test Cases significantly simplifies integrators’ need to do application-specific programming. TSI ensures the compatibility of the application software with any Unigraf test equipment hardware. Both TSI and Test Cases ensure the user flexibility for future upgrades and, what is a major cost factor, re-use of the written code of the software.

Unigraf's Unique Electrical Tests

In production line testing it is crucial to ensure that components in the DUT are functional and soldering process and assembly were successful. UCD-240’s Electrical Test can verify whole USB-C connector with single cable insertion. Electrical Test verifies that all the connector pins are properly soldered. With Electrical Test you can make sure that components in the DUT are functional and soldering and assembly of the components is done properly.
