The quantum data 980 DP Video Generator / Analyzer module is equipped with all the standard video timings and test patterns for testing high end displays including tests for protocols such as HDCP and EDID.

You can configure the list of video format timings and test patterns using the Format List Editor and Image List Editor. This facilitates convenient and quick access during testing. The module provides a Format Editor for creating custom format timings or for quickly making modifications to existing timings for testing.

The 980 DP Video Generator / Analyzer module offers a variety of features for testing DisplayPort protocols. You can control the module’s link training parameters through the user friendly 980 GUI Manager. You can set the limits on the lane count and link rate and allow the link training engine to establish link training based on those limitations or you can force link training parameters—lane count, link rate, voltage swing, pre-emphasis.

The 980 DP Video Generator / Analyzer module offers a comprehensive solution for HDCP 2.2/2.3 compliance testing covering sources, sinks and repeaters which has now been approved by Digital Content Protection (DCP).

The 980 DP Video Generator / Analyzer module now offers DisplayPort 1.2 Link Layer compliance testing for sink devices (displays).

The EDID Decode feature enables you to examine the contents of the EDID of the connected display in human readable text. The DPCD Decode feature enables you to examine the DPCD registers of the connected display in human readable text.

The optional Auxiliary Channel Analyzer (ACA) application enables you to monitor the DisplayPort Aux Channel for link training and HDCP transactions--versionns 1.3 and 2.2--as well as EDID exchanges between the module and a connected display. You can monitor in real time through the 980B’s embedded touch display and save files for later viewing or for sharing with colleagues at other locations.

The 980 DP1.2 Video Generator / Analyzer module can be controlled either through the PC-based 980 GUI Manager or through the embedded 980 GUI Manager running on the 980B itself. The 980B’s built-in color touch screen provides a graphical user interface (GUI) to control the instrument and to view incoming video and metadata in the Real Time mode when using the module’s optional analyzer feature available in subsequent releases.

The following is a list of options for the DisplayPort 1.4 Video Generator module. Please note that all functionality is optioned.

The option also includes the ability to emulate a Multi-Stream Transport (MST) source.

Basic Analyzer option – Enables you to view the incoming video, number of lanes, link rate, timing calorimetry and various other metadata in real time at a glance. This feature provides a basic confidence test to verify that the incoming video is essentially correct. The Basic Analyzer also enables you to emulate any EDID on the Rx port to test a source devices handling of various EDIDs. You can also configure DPCD registers for emulating on the DP Rx port. The Basic Analyzer option also enables you to emulate a DisplayPort Multi-Stream Transport (MST) branch device and MST sink nodes. The emulation capability includes the ability to present EDIDs from downstream MST sink devices and to provide a response to DPCD reads.

Protocol Analyzer (Capture/Analysis) option – Requires the Basic Analyzer option. It enables you capture the main link attributes and diagnose interoperability issues related to them. The Protocol Analyzer captures and stores main link data and provides visibility into main stream attributes, secondary data elements, K-Characters and protocol errors. The Protocol Analyzer presents these elements on a graphical timeline and in a table. You can select any transaction in the table and view its details. The capture utility also enables you to capture specific MST streams from the source. NEW! The trigger mechanisms for the capture analysis function enable developers to set conditions to ensure that the captured data includes the information they are most interested in.

NEW! Display Stream Compression (DSC) Analysis option – The module’s DSC analysis feature enables developers to view the DisplayPort DSC related protocol elements such as the picture parameter set, end of chunk packets and compression flag settings in the VBID to ensure that these elements are occurring in the video stream and that they are occurring in the proper sequence. The DSC analysis feature also captures and decompresses the video frames enabling developers to examine them for compression artifacts. The Forward Error Correction (FEC) transport mechanism, which ensures reliable, error free video transport, can also be verified.

NEW! DisplayPort Link Layer 1.4 HBR3 Source Compliance Test option – This new compliance test package (Package #3) initially includes eighteen (23) HBR3 source link layer compliance tests which test the link training and other functions at rates up to HBR3.
