980 DP 1.4 Video Generator / Analyzer - User Guide
12 Source Verification with Protocol Analyzer (Optional)
The 980 DP 1.4 Video Generator / Analyzer module is equipped with a DP 1.4 Rx port for the optional Network
Analyzer features. There are two analyzer options available:
1) Basic Analyzer – Emulates a DP 1.4 sink device including EDID, DPCD, MST, Link Training emulation.
Provides real time view of the incoming source video and metadata including status of mainstream
attributes, secondary stream attributes, link training, MST, HDCP. Also provides support for viewing the
Aux Channel transactions using the Quantum Data Auxiliary Channel Analyzer (ACA) application when
testing a DP source.
2) Protocol Analyzer (requires the Basic Analyzer license to be installed) – Provides capture and store of the
main link protocol, video and metadata including main stream attributes and secondary data from an
incoming DP source device.
12.1 Operational workflow for capturing data with your 980 DP Protocol Analyzer
This subsection describes how to use the 980 DP Protocol Analyzer to capture and analyze DisplayPort source
devices. Testing an DP source device involves the following high level steps:
1. Configure the 980 DP Protocol Analyzer Rx port with the proper EDID.
2. Connecting the DP source device.
3. View the incoming video in real time to check the status of the device under test.
4. Specify a trigger method.
5. Initiate the capturing of the data.
6. Examine the test data through the 980 GUI Manager at the high level view on the Event Plot panel or the
Video Analysis panel.
7. Drill down to examine the data at the lower level through the details of the Data Decode panel view.
8. (Optional) You may wish to capture and view the raw hex data.
12.2 Opening an Existing Capture
The DisplayPort Protocol Analyzer feature enables you to save capture data for later examination. You can access
existing captures through the Navigator utility as shown in the screen shot below. The right click menu enables
you to open a capture. You can also open a capture from the Open option on the File menu on top (shown below).
