Description

UCD-400 is an HBR3 capable 8K video generator and analyzer. With UCD-400 you can verify DisplayPort™ interfaces up to 8K@30 Hz (8K@60 Hz with DSC) and 4K@120 Hz video modes. The unit supports FEC, DSC, and LTTPR. UCD-400 is approved as official DP 1.4a Link Layer including DSC and HDCP 2.3 compliance test tool.

Reliable Compliance Testing Tool

DP 1.4a Link Layer, DSC and HDCP 2.3 CTS

UCD-400 is a VESA Certified DP 1.4a Link Layer Compliance Test Tool for Sinks, Sources and Branches. UCD-400 is also a DCP LLC Approved Test Tool for HDCP 2.3 Compliance Testing of Transmitters, Receivers and Repeaters on the DisplayPort interface.

VESA requires Link Layer and HDCP testing as part of the DisplayPort testing requirement for certification. If a DisplayPort receiver or transmitter supports HDCP (as reported in the product CDF) it shall be tested as part of the certification requirements for obtaining the DisplayPort Logo.

Please refer to the DP CTS Tool Options for UCD-400 to get an overview of provided tests for DP 1.4a Link Layer, DSC and HDCP 2.3 Compliance Tests

Platform for Test Automation

UCD-400 supports test automation to be used in R&D debugging or validation, compliance tests or functional tests in the production environment 

UCD-400 software package includes an SDK with 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 complete set of Compliance Tests. 

 

 

Unique Features

UCD Console GUI:

UCD Console is Unigraf’s common Graphical User Interface (GUI) for all UCD series productsUCD 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 audiovideo and audio pattern generator, data logger for AUX and metadata contentlink and DPCD register monitoring and control dialogsEDID 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.

Dolby Vision™, HDR 10 and HDR 10+

The unit is capable of playback functionality on the source side to output HDR formats such as Dolby Vision™, HDR 10 and HDR 10+ for resolutions up to 8K@60 Hz. Playback of compressed audio formats including Dolby Atmos™ is supported. Dolby Laboratories provides users with Dolby Vision content.

Capturing video and SDP including audio packets provides the data for validation of HDR and Dolby Vision.

The test device makes for an ideal tool for developers of DisplayPort 1.4a compliant ASICs and devices like PCs, graphics cards, televisions, gaming monitors and VR/AR goggles that support HDR formats and want to have their products certified for Dolby Vision.

 

LTTPR (Link Training Tunable PHY Repeaters):

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.

Display Stream Compression (DSC)

DSC feature is available as a software add-on to UCD-400. DSC feature includes both tools for encoding and decoding DSC content, which enables DSC CTS and related tests in DP Link Compliance Test tool.

DSC Decoder allows the user to preview DSC images on the UCD Console. DSC Encoder allows users to convert image bitmaps into DSC encoded custom patterns to be transmitted with the built-in pattern generator on the UCD Console.
