980B DP1.2视频信号源

980B DP1.2视频信号源支持对高端显示设备进行视频功能性980B DP1.2视频信号源测试，1,2或4路的链速率可达5.4Gb/s。此信号源有两个DP1.2输出端口——可同步输出——用来测试带有多个DP输入端口显示设备。目前的版本可以支持DP终端设备的视频图像测试，未来的版本还将实现对DP1.2源端设备的基本分析功能。

980B DP1.2视频信号源内设所有必要的标准视频格式和视频图像，用来测试显示设备，也支持HDCP和EDID的协议测试。使用者可以通过Format List Editor和Image List Editor,来配置视频格式和视频图像列表，便于测试及快速存取。设备提供了一个Format Editor,用于创建自定义格式或快速修改现有的视频格式，便于测试。

980B DP1.2视频信号源提供了多种测试DP协议的功能。ACA选件可以用来监控该设备和与之连接的显示设备之间的DP辅助通道，查看链路和HDCP、EDID相关信息。使用者可以通过980D的嵌入式触摸屏进行实时监控，也可保存文档便于以后查看或与其他地方的同事共享。

EDID解码功能是以可读文本方式检查显示设备的EDID内容，DPCD解码功能则用于以可读文本方式检查显示设备的DPCD寄存器。

使用者可以通过PC平台或者980B本身的GUI来控制980B。980B内置的彩色触摸屏提供了一个GUI来控制设备，在后续的版本里使用一些分析功能选件时，还可以查看实时状态下传入的视频和元数据。

 

The 980 DP1.2 Video Generator module supports video functional testing at link rates up to 5.4Gb/s with 1, 2, or 4 lanes for testing high-end displays. The module features two (2) DisplayPort 1.2 outputs—both active simultaneously—for testing displays with multiple DisplayPort inputs. The initial release of the module supports the video pattern testing for DP sink devices. Future releases will offer basic analysis for testing DisplayPort 1.2 source devices. The 980 DP1.2 Video Generator module can be equipped in of the 980B Advanced Test Platform with a 5-slot, 15" touch display

The 980 DP1.2 Video Generator 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 DP1.2 Video Generator 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 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 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 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.
