INTRODUCTION
QPHY-USB3-Tx -Rx is a software package designed to capture, analyze, and report measurements in
conformance with SuperSpeed USB electrical specification standard. A copy of the specification can be found at
www.usb.org.
Compatibility
QPHY-USB3-Tx -Rx is a software option compatible with the following LeCroy X-Stream oscilloscopes:
WM813Zi, SDA813Zi, DDA813Zi (4x40 GS/s, 2x80GS/s) and higher bandwidth equivalents.
SDA II and Eye Doctor II software is required.
The TF-USB3 test fixture set is required for QPHY-USB3-Tx-Rx. This fixture set includes an A-Plug, A-Receptacle
and B-Receptacle fixtures. The Tx+, Tx-, Rx+ and Rx- signals are routed via low loss traces to SSMP connectors.
Eight 2 inch SSMP to SMA cables are provided with the TF-USB3 kit.

QualiPHY Compliance Test Platform
QualiPHY is LeCroy’s unique compliance test framework which leads the user through the compliance tests.
QualiPHY displays connection diagrams to ensure tests run properly, automates the oscilloscope setup, and
generates full compliance reports.
QualiPHY makes USB 3.0 compliance testing easy and fast.
The QualiPHY software application automates the test and report generation.

917719 Rev A 7
See the QualiPHY Operator’s Manual for more information on how to use the QualiPHY framework.

QPHY-USB3-Tx-Rx Software Option
Oscilloscope Option Key Installation
An option key must be purchased to enable the QPHY-USB3 option. Call LeCroy Customer Support to place an
order and receive the code.
Enter the key and enable the purchased option as follows:
1. From the oscilloscope menu select Utilities Utilities Setup...
2. Select the Options tab and click the Add Key button.
3. Enter the Key Code using the on-screen keyboard.
4. Restart the oscilloscope to activate the option after installation.
Typical (Recommended) Configuration
QualiPHY software can be executed from the oscilloscope or a host computer. The first step is to install QualiPHY.
Please refer to the QualiPHY O perator’s Manual for installation instructions.
LeCroy recommends running QualiPHY on an oscilloscope equipped with Dual Monitor Display capability (Option
DMD-1 for oscilloscopes where this is not standard). 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.
By default, the oscilloscope appears as a local host when QualiPHY is executed in the oscilloscope. Follow the
steps under Oscilloscope Selection (as follows) and check that the IP address is 127.0.0.1.
Remote (Network) Configuration
It is also possible to install and run QualiPHY on a host computer, controlling the oscilloscope with a Network/LAN
Connection.
The oscilloscope must already be configured, and an IP address (fixed or network-assigned) must already be
established.
Oscilloscope Selection
Set up the oscilloscope using QualiPHY over a LAN (Local Area Network) by doing the following:
1. Make sure the host computer is connected to the same LAN as the oscilloscope. If unsure, contact
your system administrator.
2. From the oscilloscope menu, select Utilities Utilities Setup…
3. Select the Remote tab.
4. Verify the oscilloscope has an IP address and the control is set to TCP/IP.
5. Run QualiPHY in the host computer and click the General Setup button.
6. Select the Connection tab.
7. Enter the IP address from step 4 (previous).
8. Click the Close button.
QualiPHY is now ready to control the oscilloscope.
917719 Rev A 9
QualiPHY tests the oscilloscope connection after clicking the Start button. The system prompts you if there is a
connection problem. QualiPHY’s Scope Selector function can also be used to verify the connection. Please refer
to the QualiPHY Operator’s Manual for explanations on how to use Scope Selector and other QualiPHY
functions.
Accessing the QPHY-USB3-Tx-Rx Software using QualiPHY
This topic provides a basic overvi ew of QualiP HY’s capabilities. Please refer to the QualiPHY Operator’s Manual
for detailed information.
Access the QPHY-USB3-Tx-Rx software using the following steps:
1. Wait for the oscilloscope to start and have its main application running.
2. Launch QualiPHY from the Analysis menu if installed on the oscilloscope or from the desktop icon if
installed on a host computer.
3. From the QualiPHY main window (as follows), select Standard, then USB3.0 SS from the pop-up menu
(if not already selected). If you check the Pause on Failure box (circled) QualiPHY prompts to retry the
measure whenever a test fails.

QPHY-USB3-Tx-Rx Software Option
4. Click the Configuration button in the QualiPHY main menu.
5. Select a configuration from the pop-up menu. For addition information, please refer to the
QPHY-USB3-Tx -Rx Test Configurations section of this manual.
Figure 5. QualiPHY configuration selection menu
6. Click Start.
7. Follow the pop-up window prompts.
917719 Rev A 11
Customizing QualiPHY
The predefined configurations in the Configuration screen can be modified but can only be saved as a new
configuration. You can also create your own test configurations by copying one of the standard test configurations
and making modifications. A description of the test is also shown in the description field when selected.

12 917719 Rev A
QPHY-USB3-Tx-Rx Software Option
Creating Custom Configurations
Beginning with any of the pre-loaded configurations,
1. Click on the Test Selector tab to change what tests you would like to be included in your new
configuration.
2. Click on the Variable Setup tab to change the variables for your new configuration.
For additional information, refer to the QPHY-USB3-Tx-Rx Variables section of this manual.
3. Click on the Limits tab to change which limit set should be used for your new configuration
For additional information, refer to the QPHY-USB3-Tx-Rx Limits section of this manual.
4. Once a change has been made to any of these sections, the Save As button is enabled at the bottom of
the dialog.
5. Clicking the Save As button prompts you for a new configuration name and description.
Note: If a Custom Configuration was used for the procedure, the Save button is also enabled on the bottom of the dialog. Clicking this button
updates the current configuration with new changes. Additionally, if the user does not wish to save their changes, they can chose to run
QualiPHY with the variables set as the want without saving. However, when the user attempts to switch to another configuration, the system
prompts to save or abandon the current configuration.
6. Once a custom configuration is defined, script variables and the test limits can be changed by using the
Variable Setup and Limits Manager from the Edit/View Configuration window.

QPHY-USB3-Tx-Rx Operation
After pressing Start in the QualiPHY menu, the software instructs how to set up the test using pop-up connection
diagrams and dialog boxes. QualiPHY also instructs how to properly configure the Product Under Test (PUT) to
change test signal modes (when necessary).
