DisplayPort over USB-C test tool is automated
Video electronics testing company, Unigraf offers its latest DisplayPort over USB-C test tool, the UCD-240 USB-C Test Automation Tool. UCD-240 is specifically designed for test automation in the production line environment. It is described as a comprehensive test automation tool supporting DP Alt Mode, 4k at 60Hz and NI TestStand. UCD240 test coverage includes all essential features of the USB-C interface, says Unigraf.
As new USB Type-C products are introduced, the need for cost-effective USB-C test automation in production line environment increased. UCD-240 is intended for production line testing of any USB Type-C products including smartphones, laptops, tablets and more.
The UCD-240 has built-in tests for video, audio, link and electrical tests. The electrical test can verify whole USB-C connector with single cable insertion. It verifies that all the connector pins are properly soldered.
Automated tests for USB-C power delivery and USB 2.0 and 3.0 functionalities are also supported.
UCD-240 can be used via different software platforms and is delivered for test automation, including all necessary hardware, software, test sequences and accessories.
Unigraf’s UCD console graphical user interface (GUI) is also included for efficient setting of all necessary test parameters for automated tests. It is possible to run tests using three different platforms.
Automated tests can be run straight from the command-line. Running automated tests from the command-line is the simplest and most cost-effective way of conducting automated tests for USB Type-C interface, explains Unigraf. Running tests from command-line batch files means that no additional software is needed. Software provided can set and save all necessary test parameters which can be called from a known location from the command-line.
UCD-240 also supports Unigraf’s test system interface (TSI).The nature of tests, means that many R&D TSI tests are specific to certain interface and test equipment The structure of the TSI test calls is uniform, making it straightforward for the user to swap and re-use test applications between test set-ups, says Unigraf, to save time. Unigraf’s TSI API with C++ can be used as an alternative when test engineers want to integrate UCD device control and TSI tests on existing C++ code for an efficient and cost-effective way of implementing new automated tests into existing test automation set-ups.
Developers can use a third-party test management software e.g. National Instrument’s TestStand, which is a ready-to-run test management environment and framework designed to simplify the automation of test and validation systems. NI TestStand is used to develop, manage and execute test sequences. It provides a common unified environment and interface for all the different cases of automated testing. NI TestStand also integrates with enterprise systems, such as database management systems to incorporate easy database logging of test results.
In production line testing it is crucial to ensure that components in the device under test are functional and that the soldering process and assembly were successful. UCD-240’s electrical test can verify whole USBC connector with single cable insertion. It also verifies that all the connector pins are properly soldered.
