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-PCIE3-TxRx

QPHY-PCIE3-TxRx is an automated test package performing all the Tx and Rx receiver tests in
accordance with PCI Express Card Electromechanical Specification, Rev. 3.0.

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 to check that the IP address
is 127.0.0.1.

Install SigTest.exe

SigTest.exe ver. 3.2.0, which is the current version required by the PCI SIG, must be installed on
the oscilloscope for the PCIE3-TxRx script to execute properly. It is available for download from
the PCI SIG website.

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
when purchasing a software option.

To activate a component on the oscilloscope:

1. From the menu bar, choose Utilities > Utilities Setup.

2. On the Options tab, click Add Key.

3. Use the Virtual Keyboard to Enter Option Key, then click OK.

If activation is successful, the key code now appears in the list of Installed Option Keys.

4. Restart the oscilloscope application by choosing File > Exit, then double-clicking the

Start DSO icon on the desktop.

923662 Rev B 3

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.

Set Up Remote Control

QualiPHY software can be executed from a remote host computer, controlling the oscilloscope
through a LAN Connection. To set up remote control:

 The oscilloscope must be connected to a LAN and assigned an IP address (fixed or

dynamic).

 The host computer must be on the same LAN as the oscilloscope.

Note: LXI, GPIB, LSIB, and USBTMC remote control is available for some model instruments.
Follow the same procedure, selecting the appropriate connection type on the oscilloscope and
in QualiPHY.

Configure Oscilloscope for Remote Control

1. From the menu bar, choose Utilities  Utilities Setup...

2. Open the Remote tab and set Remote Control to TCP/IP.

3. Verify that the oscilloscope shows an IP address.

Add Connection to QualiPHY

1. On the host PC, download and run QualiPHYInstaller.exe.

2. Start QualiPHY and click the General Setup button.

3. On the Connection tab, click Scope Selector.

4. Click Add and choose the connection type. Enter the oscilloscope IP address from Step
3 above. Click OK.

5. When the oscilloscope is properly detected, it appears on the Scope Selector dialog.
Select the connection, and click OK.

QualiPHY is now ready to control the oscilloscope.

Select Connection

Multiple oscilloscopes may be accessible to a single remote host. In that case, go to General
Setup and use the Scope Selector at the start of the session to choose the correct connection.

QualiPHY tests the oscilloscope connection when starting a test. The system warns you if there
is a connection problem.

Using QualiPHY

This section provides an overview of the QualiPHY user interface and general procedures,
using examples from the QPHY-BroadR-Reach option. For detailed information about the
QPHY-PCIE3-TxRx software option, see QPHY-PCIE3-TxRx Testing.

Accessing the Software

Once QualiPHY is installed and activated, it can be accessed from the oscilloscope menu bar by
choosing Analysis > QualiPHY, or by double-clicking the QualiPHY desktop icon on a remote
computer.

The QualiPHY framework dialog illustrates the overall software flow, from general set up through
running individual compliance tests. Work from left to right, making all desired settings on each
sub-dialog.

Figure 1 - QualiPHY framework dialog and Standard selection menu.

The sub-dialogs are organized into tabs each containing configuration controls related to that
part of the process. These are described in more detail in the following sections.

If Pause on Failure is checked, QauliPHY prompts to retry a measure whenever a test fails.
Report Generator launches the manual report generator dialog.
The Exit button at the bottom of the framework dialog closes the QualiPHY application.

923662 Rev B 5

General Setup

The first sub-dialog contains general system settings. These remain in effect for each session,
regardless of Standard, until changed.

Connection tab

Shows IP Address of the oscilloscope (local host 127.0.0.1 if QualiPHY is run from the
oscilloscope). The Scope Selector allows you to choose the oscilloscope used for testing when
several are connected to the QualiPHY installation. See Set Up Remote Control for details.

Session Info tab

Optional information about the test session that may be added to reports, such as: Operator
Name, Device Under Test (DUT) name, Temperature (in C) of the test location, and any

additional Comments. There is also an option to Append Results or Replace Results when
continuing a previous session.

To optimize report generation, enter at least a DUT name at the beginning of each session.

Report tab

Settings related to report generation. Choose:

 Reporting behavior of:

o “Ask to generate a report after tests,” where you’ll be prompted to create a new

file for each set of test results.

o “Never generate a report after tests,” where you’ll need to manually execute the

Report Generator to create a report.

o “Always generate a report after tests,” to autogenerate a report of the latest test

results.

 Default report output format of XML, HTML, or PDF.

Note: Unlike some QualiPHY components, PCIE-TxRx does not overwrite a generic file

when autogenerating reports, but creates a new report file each session named
“LeCroyReport_<DUT name>” (or if DUT is empty, “LeCroyReport_DUT”). You can omit
entering an Output file name.

Optionally, check Allow style sheet selection in Report Generator to enable the use of a
custom .xslt when generating reports (XML and HTML output only). The path to the .xslt is
entered on the Report Generator dialog.

Report Generator launches the Report Generator dialog, which contains the same settings as
the Report tab, only applied to individual reports.

Advanced tab

This tab launches the X-Replay Mode dialog. See X-Replay Mode.
