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 QPHYPCIE3 software option. Some of the images in this manual may show QualiPHY products other than QPHY-PCIE3, 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 a highly automated compliance test software meant to help you develop and validate the PHY (physical-electrical) layer of a device, in accordance with t he 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: Parameter interconnect losses can be factored into the parametric results.

• 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

QPHY-PCIE3 is an automated test package performing all the normative, real-time oscilloscope tests for sources in accordance with PCI Express Card Electromechanical Specification, Rev.

3.0. The software can be run on any Teledyne LeCroy real-time oscilloscope with at least 13 GHz

bandwidth and a sample rate of at least 40 GS/s.

Required Hardware

• Real-time Teledyne LeCroy oscilloscope with the QualiPHY software and an activated QPHY-PCIE3 component

• DC blocks

• 1 pair standard SMA-SMP cable and 3 pair short SMA-SMP cables

• 2 pair standard SMA-SMA cable and 2 pair high-quality SMA-SMA cables

• PCIE 3.0 test fixtures (e.g., CBB3)

• PCIe load board

• SMP extractor tool

• Torque wrench

• Power supply

For the most complete and up-to-date list, see the PCI SIG website: www.pcisig.com/specifications/pciexpress/compliance

922544 Rev A 1

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 RA M

• 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 execut ed 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 when purchasing a software option.

To activate a component on the oscilloscope:

1. From the menu bar, choose Utilities > Utilit ie s 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 Opt ion Keys.

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

Star t DSO icon on the desktop.

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 Contr ol

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 Remot e Cont rol

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 software option, see QPHY-PCIE3 Testing

Accessing the Softw ar e

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, fro m 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.
