2. Purpose
This document is intended to provide the measurement procedures for High-Definition
Multimedia Interface (HDMI) Ethernet and Audio Return Channel (HEAC) cable
assemblies with Keysight E5071C ENA Option TDR. The procedures are designed to
perform tests equivalent to the methodologies defined in the HDMI Compliance Test
Specification (CTS) Version 1.4b.

5.2.Instrument Setup
This section describes procedures for recalling the state file and VBA macro that support the
instrument setup. Download "HEAC cable assembly test package" from
http://www.keysight.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 Error! Reference source not found. Error!
