Create your own custom formats using the user friendly Format Editor. Scroll bitmap patterns to test for motion artifacts. Create custom test pattern lists and custom format lists to facilitate testing.

Display Stream Compression (DSC) Video Generator option – The module’s DSC/FEC video generator feature enables display developers to transmit DSC/FEC streams. Users can selection from several test patterns and configure the colorimetry and DSC slice configurations.

Protocol Testing – The 980 DP 1.4 Video Generator / Analyzer module offers a variety of features for testing DisplayPort protocols. The module’s EDID Decode feature enables you to examine 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.

Protocol Analysis - The DP module’s optional Rx analyzer port emulates a DisplayPort display device including EDID and DPCD emulation, Rx Link Training function and MST Rx function. The Basic analyzer option enables you to view the real time video, main link video parameters and the secondary data packets. A second analyzer option enables you to capture and store the incoming DisplayPort stream from a source for detailed analysis of the main stream protocol elements including the main stream attributes and secondary data elements. 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.

Display Stream Compression (DSC) Analysis option – The module’s optional DSC analysis feature enables developers to view the DisplayPort DSC video and metadata in real time as well as 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. Test engineers can also verify the DSC compressed stream using the Test CRC registers in the module's DPCD registers.

Link Training Configuration Utility – The link training control features enables you to configure the module’s link training parameters during testing. You can set 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.

HDCP Testing – Verify a downstream DisplayPort display’s response to HDCP 1.3 or HDCP 2.2 authentication. View status of authentication and exchange of registers. Support also includes HDCP 2.2 Compliance Testing for source, display and repeater devices.

Multi-Stream Transport Testing – Emulate an MST source for testing an MST branch device or MST-capable monitor. Up to four (4) streams are supported depending on bandwidth (resolutions) with a depth of one. You can configure the MST topology using a graphical interface. Users can read the EDID and DPCD registers of specific downstream MST display nodes. The optional Auxiliary Channel Analyzer (ACA) utility depicts the MST negotiations with the connected MST sink device.

Aux Channel Monitoring - The Auxiliary Channel Analyzer (ACA) application enables you to monitor the DisplayPort Aux Channel for link training and HDCP transactions--versions 1.3 and 2.2--as well as EDID exchanges between the module and a connected display. NEW! If you have the USB-C DP Alt mode option enabled, you can monitor the Power Deliveriy (PD) protocol negotiations into DP Alt mode through the ACA as well. 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.

Passive Aux Channel Monitoring - The DP 1.4 module includes an auxiliary board and associated custom cable for passively monitoring the DisplayPort aux channel transactions  between a DisplayPort HBR3 source and sink using the familiar Auxiliary Channel Analyzer utility. The ability to passively monitor the aux channel transactions between a source and a display is invaluable in identifying the root cause of link training issues between two devices.

The following is a list of options for the DisplayPort 1.4 USB-C/eDP Video Generator / Analyzer module. The module can be ordered with either or both of the connector types activated: 1) Tx/Rx DisplayPort standard ports 2) Tx/Rx USB-C DisplayPort Alt Mode ports.

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. 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.
