Unigraf UCD-400 supports test automation to be used in R&D debugging or validation, compliance tests or functional tests in the production environment.
Unigraf UCD-400 software package includes an SDK with a scripting and programming API. Unigraf’s Test System Interface (TSI) allows system integrators a fast and reliable way of implementing the functionality of the test. TSI is very flexible. It can be used either for various kinds of video and audio tests or to automate a complete set of Compliance Tests.
UCD Console is Unigraf’s common Graphical User Interface (GUI) for all UCD series products. UCD Console is available for Windows, Linux and macOS operating systems.
UCD Console enables users to access all test features of the UCD-400. It provides users with a flexible way of navigating between its sink and source roles and functionalities of each role.
Available functionalities include preview windows for captured video and audio, video and audio pattern generator, data logger for AUX and metadata content, link and DPCD register monitoring and control dialogs, EDID editor, HDCP status and control functions etc.
UCD Console is delivered with ready-made test sets (e.g. content check-sum tests and Link Training tests) for testing DisplayPort Sinks and Sources.
LTTPR is a feature that helps maintain signal integrity between DisplayPort Source and Sink by letting each repeater optimize the signal path with link training. UCD-400 is able to act as a DisplayPort source controlling the LTTPRs in the downstream signal path. LTTPR Test is a software addition for the UCD-400.
UCD Console is Unigraf’s common Graphical User Interface (GUI) for all UCD series products. UCD Console is available for Windows, Linux and macOS operating systems.
Unigraf UCD-400 device is delivered with UCD Console and Test System Interface (TSI) System Development Kit (SDK) for DisplayPort Sinks and Sources. Please, refer to the table below to see the default tests provided with UCD Console and TSI SDK.
Note: HDCP 2.3 Support is also delivered with the UCD-400 device.
