The quantumdata 980 DP 1.4 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 1.4 module now supports video generation of Display Stream Compression (DSC) and Forward Error Correction (FEC) for testing DSC-capable display devices. Users can select from several test patterns and then select the colorimetry settings and DSC slice configurations.

The 980 DP 1.4 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 1.4 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 1.4 Video Generator / Analyzer module offers DisplayPort 1.4 Link Layer compliance testing for HBR3-capable source and sink devices (displays). NEW! Forward Error Correction (FEC) tests are also now supported.

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 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. 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 module offers an option for passively monitoring the DisplayPort aux channel transactions between a DisplayPort HBR3 source and sink using the familiar Auxiliary Channel Analyzer utility. This option uses an auxiliary board and a custom cable provided with the option. 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 980 DP 1.4 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 are a list of features and benefits for the DisplayPort 1.4 Protocol Analyzer / Video Generator module. Refer to the Options tab for information on optional features.

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. 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 Video Generator module. Please note that all functionality is optioned.

Video Generator option – Enables you to emulate a DisplayPort source device for video pattern testing.
