10 Running Standard Tests

This chapter describes how to use the 980 HDMI Protocol Analyzer special tests. The 980 HDMI Protocol Analyzer
supports the following special tests:
 Video timing analysis – Verifies that the timing parameters from an HDMI source device including all
horizontal and vertical parameters.
 Video analysis – Enables you to check the video parameters and pixel values from the HDMI source device.

Audio analysis - Identify audio inconsistencies in metadata related to sampling rate and audio clock recover
that could result in interoperability problems.
AVmute – Verifies that an HDMI source has implemented Avmute properly.


10.1 Running a video timing test

The procedures below describe how to run the video timing test on an HDMI source device through the 980 GUI
Manager. This subsection describes how to use the 980 HDMI Protocol Analyzer to run a timing test on an HDMI
source device. The setup procedures described above in the section:
Analyzer should be followed for the timing tests. These setup procedures are listed below:
1. Configure the 980 HDMI Protocol Analyzer in the proper mode HDMI.
2. Set the threshold of the +5V.
3. Configure the 980 HDMI Protocol Analyzer Rx port with the proper EDID.
4. View the incoming video in real time to check the status of the device under test.
To run the video timing test:
1. Select the 980 HDMI Protocol Analyzer that you are using to capture the data from your HDMI source device
under test from the pull-down menu.
2. Set the Capture Buffer Size slidebar to a percent value to meet your requirements. You can capture up to
about 2GB of data which is about 1150 frames at 576p/480p and about 204 frames at 1080p which includes
the video. If you do not want to capture the video and only capture the metadata, you can store well over
100,000 frames of data.
3. Set the Capture Buffer Position slidebar to a percent value to meet your requirements. This slide bar enables
you to set the position of the trigger event within the captured data. This is a slidebar that provides an
