6 Analyzing HDMI Protocol Data with your 980 Protocol Analyzer

This chapter describes how to use the 980 Protocol Analyzer to view HDMI protocol data from the HDMI source
device under test.
6.1

Overview

These procedures assume that you have powered up the 980 Protocol Analyzer, connected your HDMI source
device (and possibly sink device if you are testing in the optional pass-through mode), connected the Ethernet
cable and established an IP connection from the 980 GUI Manager running on your PC to the 980 Protocol
Analyzer application. You should now have the 980 Protocol Analyzer Manager open on your PC.
6.2

Operational workflow for capturing data with your 980 Protocol Analyzer

This subsection describes how to use the 980 to capture and analyze HDMI source devices. It assumes you have
established a connection to the 980 from the 980 Manager. Testing an HDMI source device involves the following
high level steps:
1. Determine what operational configuration you are using: 1) Sink Emulation, 2) Pass-Through, 3) Encrypted
Link Analyzer. If you are using the Pass-Through or Encrypted Link Analyzer configuration connect an HDMI
display device to the HDMI Tx port. If using the Sink Emulation mode you do not need to connect any device
to the HDMI Tx port.
2. Configure the 980 Rx port with the proper EDID.
3. View the incoming video in real time to check the status of the device under test.
4. Specify the data that you want to capture and how much data you want to capture.
5. Specify a trigger method.
6. Initiate the capturing of the data.
7. Examine the test data through the 980 GUI Manager at the high level view on the Event Plot panel or the
Video Analysis panel.
8. Drill down to examine the data at the lower level through the details of the Data Decode panel view.
9. Use the analysis tools (Video Analysis, Timing Analysis, Audio Analysis, AVmute Test) to examine the data.
10. (Optional) If you have purchased the HDMI source compliance test option you can run these test suites as
well.
6.3

Setting the Configuration of the Link Mode

Prior to a capturing or viewing video you will need to set the configuration of the Link Mode: 1) Sink Emulation, 2)
Pass-Through, 3) Encrypted Link Analyzer. If you are using the Pass-Through or Encrypted Link Analyzer
configuration you will connect an HDMI display device to the HDMI Tx port. If using the Sink Emulation mode you
do not need to connect any device to the HDMI Tx port. Use the following procedures to select the configuration
mode.
Note: The procedures in this subsection assume that you are capturing data in the Sink Emulation Mode. The
procedures for capturing data in the Pass-Through and Encrypted Link Analyzer mode are provided later in this
User Guide.
