About This Manual
This manual assumes that you are familiar with using an oscilloscope−in particular the Teledyne
LeCroy oscilloscope that will be used with QualiPHY−and that you have purchased the QPHYHDMI software option. Some of the images in this manual may show QualiPHY products other
than QPHY-HDMI, or were captured using different model oscilloscopes, as they are meant to
illustrate general concepts only. Rest assured that while the user interface may look different
from yours, the functionality is identical.

Introduction
About QualiPHY
QualiPHY is highly automated compliance test software meant to help you develop and validate
the PHY (physical-electrical) layer of a device, in accordance with the official documents
published by the applicable standards organizations and special interest groups (SIGs). You can
additionally set custom variables and limits to test compliance to internal standards.
QualiPHY is composed of a “framework” application that enables the configuration and control
of separate tests for each standard through a common user interface. Features include:
• Multiple Data Source Capability: Connect to your X-Stream oscilloscope via LAN or
other interfaces.
• User-Defined Test Limits: Tighten limits to ensure devices are well within the passing
region, even if subsequently measured with different equipment.
• Flexible Test Results Reporting that includes XML Test Record Generation.
Understand a device performance distribution, or obtain process related information from
the devices under test.
About QPHY-HDMI
QPHY-HDMI is an automated test package performing all the normative, real-time oscilloscope
tests for sources in accordance with version 1.4 of the High Definition Multimedia Interface
Compliance Test Specification (HDMI).
The software can be run on any Teledyne LeCroy oscilloscope with at least 8 GHz bandwidth
(for testing clock rates above 148.5 MHz). The oscilloscope must also have the QualiPHY
software installed and the QPHY-HDMI software option activated.
Required Hardware
• Real-time Teledyne LeCroy oscilloscope with all required software installed.
Note: QPHY-HDMI tests are designed to run on WavePro/SDA/DDA 7Zi/ZI-A,
WaveMaster/SDA/DDA Zi/Zi-A, LabMaster 9Zi/Zi-A Series oscilloscopes with minimum
8GHz bandwidth. The HDMI test specification requires 8 GHz bandwidth for testing clock
rates above 148.5 MHz.
• SDAII or SDAIII oscilloscope software option. (SDAII / SDIII is standard on SDA model
oscilloscopes)
• 8 SMA Male to SMA Male cables
• 4 TF-HDMI-3.3V test adapters
• HDMI test fixtur e
For the most complete and up-to-date list, see the HDMI SIG website: http://www.hdmi.org

Test Fixtures
Teledyne LeCroy recommends using the Wilder Technologies HDMI-TPA-P (plug test adapter)
used in conjunction with HDMI-TPA-E (EDI D board with EEPROM). This equipment is available
from Wilder Technologies individually or as part of the HDMI-TPA-PRRCE Test Adapter Kit. The
HDMI-TPA-PRRCE test adapter kit provides a very high bandwidth, low noise evaluation vehicle
that enables high-performance characterization of both plug and receptacle HDMI™ devices
with bandwidth greatly exceeding the 340 MHz (10.2 Gbps) of the latest v1.4b HDMI
specification.
Required Host Computer System
Usually, the oscilloscope is the host computer for the QualiPHY software, and all models that
meet the acquisition requirements will also meet the host system requirements. However, if you
wish to run the QualiPHY software from a remote computer, these minimum requirements apply:
• Operating System:
o Windows 2000 Professional with service pack 4
o Windows XP Professional with service pack 2
o Windows VISTA with service pack 1
o Windows 7 Professional
• 1 GHz or faster processor
• 1 GB (32-bit) or 2 GB (64-bit) of RAM
• Ethernet (LAN) network capability
• Hard Drive:
o At least 100 MB free to install the framework application
o Up to 1GB per standard installed to store the log database (each database grows
from a few MB to a maximum of 1 GB)
See Set Up Remote Control
for configuration instructions.

Installation and Setup
QualiPHY is a Windows-based application that can be configured with one or more serial data
compliance components. Each compliance component is purchased as a software option.
Install Base Application
Download the latest version of the QualiPHY software from:
teledynelecroy.com/support/softwaredownload under Oscilloscope Downloads > Software Utilities.
If the oscilloscope is not connected to the Internet, copy the installer onto a USB memory stick,
then transfer it to the oscilloscope desktop or a folder on a D:\ drive to execute it.
Run QualiPHYInstaller.exe and follow the installer prompts. Choose all the components you
plan to activate. If you omit any components now, you will need to update the installation to
activate them later.
By default, the oscilloscope appears as local host when QualiPHY is executed on the
oscilloscope. Follow the steps under Add Connection to QualiPHY
is 127.0.0.1.
to check that the IP address
Activate Components
The serial data compliance components are factory installed as part of the main application in
your oscilloscope and are individually activated through the use of an alphanumeric code
uniquely matched to the oscilloscope’s serial number. This option key code is what is delivered

Set Up Dual Monitor Display
Teledyne LeCroy recommends running QualiPHY on an oscilloscope equipped with Dual
Monitor Display capability. This allows the waveform and measurements to be shown on the
oscilloscope LCD display, while the QualiPHY application and test results are displayed on a
second monitor.
See the oscilloscope Operator’s Manual or Getting Started Manual for instructions on setting up
dual monitor display.
922540 Rev A 3
