2.4 Creating a Capabilities Declaration Form (CDF)
The Capabilities Declaration Form describes the capabilities of the HDMI source device under test. The CDF is
used by the 980 compliance test application to determine what test capabilities of the source device to test. The
980 HDMI Protocol Analyzer compliance test function provides a set of forms that can be filled out and saved. This
saved CDF is stored on the 980 test instrument and is used during the test. You must complete a CDF prior to
running the test scripts through your ATS.
Detailed procedures for creating a Capabilities Declaration Form (CDF) through the embedded 980 GUI Manager
are provided below. The 980 must be powered up.
Please note that you can also create a CDF through the external 980 GUI Manager. Using the external 980 GUI
Manager requires that you connect the host PC to the 980 Protocol Analyzer; therefore for testing with an ATS we
recommend just completing the CDF through the embedded 980 GUI Manager.
To complete the CDF:
1. From the Compliance menu, enable viewing of the HDMI Source Compliance Test panel.
2. Select the CDF Entry panel as shown below.
3. To create a new CDF, click on the New activation button.
You will be prompted with a confirmation that you want to start a new CDF and reset the values. Click OK to
proceed.

5. Complete the items in the Product tab of the CDF Entry panel shown below. Note that you will have to
complete the essential fields in order to proceed. A red status message (below) will appear indicating if you
have not completed all the essential fields.
6. Complete the items in the remaining tabs, then save the CDF as “cdf”. A confirmation box with a default name
will appear. Edit the name if necessary and click OK.
Note: The CDF will be saved on the 980 HDMI Protocol Analyzer in the /home/qd/workspace/hdmict/cdf/
directory. You will have to move the CDF file to the /home/qd/ directory before starting with your test
automation. Procedures for moving this file are provided in the next chapter.
2.5 Acquiring the test EDID
When running the source compliance test through an Automated Test System you will have to ensure that the
EDID provisioned in the 980 HDMI Protocol Analyzer module’s Rx port supports all video and audio capabilities
that your source device supports. Quantum Data provides the EDID(s) necessary. In most cases the Quantum
Data default EDID will be sufficient for testing your source device. You can obtain this EDID from the Quantum
Data EDID library www.quantumdata.com/edid/ or from the 980 itself. Procedures are provided in the following
chapter.

3.4 Initiating the compliance test
This section provides procedures for running a test on a source device. There are four example procedures for
each of four separate tests. The sample tests selected should give you an idea how to run any of the HDMI source
compliance tests supported by the 980 HDMI Protocol Analyzer module. The four sample tests are:
7-17 - Basic Protocol Test.
7-23 - Video Pixel Encoding RGB
7-29 –Audio Clock Regeneration

980 HDMI Protocol Analyzer Application Guide –Source Compliance Test Automation Rev. A1
Page 19 Feb 14, 2013
7-39 –4K Video Resolution
These procedures assume the following prerequisite steps have been completed:
You have created a CDF and put it in the proper directory on the 980.
You have provisioned the 980 HDMI Protocol Analyzer module’s Rx port with an EDID that supports all
source features and functions.
You have verified that you have the proper license for running the HDMI Source Compliance test option.
That you have upgraded your 980 (if necessary) to a suitable released version.
Note: The easiest way to verify that you have the proper license and that the 980 Protocol Analyzer is
equipped with the proper released version is to run a simple quick test through the 980 GUI Manager. We
recommend that you use the embedded 980 GUI Manager through the 980’s touch screen display. For
instruction on running the HDMI Compliance test through the 980 GUI Manager refer to the User Guides
available on the Quantum Data website.
The commands used in the sample procedures below have to be incorporated into the Automated Test System.
Comments are provided to help you understand the purpose and sequence of commands in the test process
necessary for compliance test automation. All commands shown at the p-scope> prompt need to be executed
by an Automated Test System.
For a description of each command, refer to the command reference at: Appendix –Command Line Reference.
3.4.1 Basic Protocol Test –Test ID 7-17 Example
The following sequence of commands are used to run the 7-17 test.
Initialization
p-scope> hdmitx disable // disables the 980 HDMI Protocol Analyzer Tx port.
p-scope> slink down // disables the Encrypted Link Analyzer mode.
p-scope> mon hdmi // configuring the 980 for HDMI (rather than DVI).
p-scope> hp // toggle hot plug to cause an EDID read by the source.
Asserting 1sec HP pulse
Note: The Automated Test System now has to put the source device into the proper video and audio mode (i.e.
resolution, colorimetry, audio format etc.). If you are certain that the source is in the proper mode executing the
following command (vinfo) is optional. Otherwise the Automated Test System would have to parse out the
command response and issue a notification to the operator.
p-scope> vinfo // verify incoming video parameters.
