INTRODUCTION

QPHY-SAS2 is a software package designed to capture, analyze, and report measurements in conformance with
UNH IOL Serial Attached SCSI (SAS) Consortium SAS-2 6Gbps Physical Layer Test Suite (Version 1.01). A copy
of the specification can be found on the UNH IOL FTP site.

Note: As of March 2nd, 2010 this document can be found at the following site but this is subject to change:
ftp://ftp.iol.unh.edu/pub/sas/test_suite/SAS-2_6Gbps_Physical_Layer_Test_Suite_(v1.01).pdf.

Compatibility

QPHY-SAS2 is a software option compatible with the following LeCroy X-Stream oscilloscopes:

 WM806Zi, SDA806Zi, DDA806Zi (4x40 GS/s, 2x80GS/s) and higher bandwidth equivalents.

 SDA II Option is required on WaveMaster oscilloscopes.
 The minimum recommended bandwidth for testing SAS-2 targets and initiators at 6Gbps is

10GHz.

MATLAB is required (either installed on the oscilloscope or on a separate PC) for running the Waveform Distortion
Penalty test.

SETUP AND INSTALLATION

The following test equipment is required to perform SAS-2 tests.

Required Equipment

 Real Time Digital Oscilloscope as listed in Compatibility section with firmware release 6.1.x.x or later, and

software option package QPHY-SAS2

 QualiPHY Software (version 6.1.0.x or later) installed on either the oscilloscope or a separate PC.
 SAS Test Fixture from Wilder Tech

 Either the SAS Plug Adapter (SAS-TPA-P) or SAS Receptacle Adapter (SAS-TPA-R) must be

used depending on the connection to the device under test.

 50Ω Coax Cable with SMA Male Connectors, qty = 2

 These cables should be nominally the same length so that the attenuation characteristics and

length are well matched. The cables should be as short as possible, while allowing connection
between the text fixtures and the oscilloscope (nominally 6 inches each).

 For the automated de-skew procedure employing the differential signals from the DUT, these

cables must be matched to better than 1/2UI of the data rate tested (e.g. less than ~160ps for 6
Gbps)

 1 PC power supply
 DC Blocks , qty =2

 <=10MHz to >=18GHz DC block are required for SAS2 testing (e.g Pasternack PE8210)

QPHY-SAS2 Software Option

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 SAS-2 compliance testing easy and fast.
The QualiPHY software application automates the test and report generation.

917718 Rev A 7

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

QPHY-SAS2 Software Option

Oscilloscope Option Key Installation

An option key must be purchased to enable the QPHY-SAS2 option. Call LeCroy Customer Support to place an
order and receive the code. The software option SDA2 is also required.

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 Operator’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) or the Network name of the scope (its serial number)

8. Use the “Test” button to verify connection to an active oscilloscope)

9. Click on the Use selected device button to use this connection (or the new selection will have no
effect)

10. Click the Close button.

QualiPHY is now ready to control the oscilloscope.

917718 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-SAS2 Software using QualiPHY

This topic provides a basic overview of QualiPHY‟s capabilities. Please refer to the QualiPHY Operator’s Manual
for detailed information.

Access the QPHY-SAS2 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.

4. Click the Configuration button in the QualiPHY main menu:

5. Select a configuration from the pop-up menu:

6. Click Start.

7. Follow the pop-up window prompts.

Customizing QualiPHY

The predefined configurations in the Configuration screen cannot be modified. However, you can 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.

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.

3. Click on the Limits tab to change which limit set should be used for your new configuration

 See QualiPHY Manual for more information

4. Once a change has been made to any of these sections, the Save As button becomes clickable on the
bottom of the dialog.

5. Clicking the Save As button will prompt you for a new configuration name and description.

Note: If a Custom Configuration was used for the procedure, the Save button will also become clickable on the
bottom of the dialog. Clicking this button will update the current configuration with new changes.

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.
