2. Purpose
This document is intended to provide the measurement procedures for High-Definition
Multimedia Interface (HDMI) cable assemblies with Agilent E5071C ENA Option TDR.
The procedures are designed to perform tests equivalent to the methodologies defined in the
HDMI Compliance Test Specification Version 1.4b (CTS). Devices under test are supposed
to be passive HDMI cables. Active cables are out of the scope of this document.

4. Resource Requirements
1. E5071C ENA Series Network Analyzer with Enhanced Time Domain Analysis Option
Note: Ensure that
- Test set option is any one of 480/485/4D5/4K5
- E5071C firmware revision A.10.05 or above is installed.
- E5071C-TDR application software revision A.01.50 or above is installed.
2. Electronic Calibration Module N4431B (for 480/485) or N4433A (for 4D5/4K5)
3. 3.5 mm cables 8 GHz bandwidth or equivalent x4
4. Certified HDMI receptacle fixtures (ex. Agilent N1080B-H05) x2
5. Certified HDMI plug fixtures (ex. Agilent N1080B-H04) x1
Note: The plug fixture is used for the jitter adjustment in the eye diagram test. It should
have similar characteristics to the receptacle fixtures.
6. 50 Ohm terminators to terminate unused fixture connectors x12
7. Female to female adaptors to connect fixture and test cables (if necessary)

5.2. Instrument Setup
This section describes procedures for recalling the state file and VBA macro that support
the instrument setup. Download "HDMI cable assembly test package" from
http://www.agilent.com/find/ena-tdr_hdmi-cabcon.
Extract the zip file and transfer the extracted files to the instrument with a USB flash
memory.
5.2.1. Recalling State File
1. If TDR setup wizard appears, click Close button on the wizard.
2. Open Setup tab (item1).
3. Click More Function (item2).
4. Click Advanced Mode (item3).

5. A dialog box appears requesting for confirmation. Then click Yes. (Clear the check box
for "Use Advanced Calibration Methods")

6. Click File (item4) and select Recall State to open the Recall State dialog box.
7. Specify a folder and a file name, and click Open.

For manual measurement setup, refer to 6 Appendix.
