QPHY-SAS3 Software Option
INTRODUCTION TO QUALIPHY SA S3
QPHY-SAS3 is an automated software package designed to capture, analyze, and report measurements
in conformance with T10 SAS-3 specification as described in the UNH IOL Serial Attached SCSI (SAS)
Consortium SAS-3 12Gbps Physical Layer Test Suite (Version 1.0). A copy of the specification can be
found on the UNH-IOL FTP site.
Note: As of May 19th, 2014 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-3_12Gbps_Physical_Layer_Test_Suite_(v1.0).pdf
The software can be run on any Teledyne LeCroy Zi Ser ies oscil losc ope wit h at lea s t 20 GHz
bandwidth and a sample rate of at least 40 GS/s. The oscilloscope must also be equipped with the
QPHY-SAS3, SDAIII and Eye Doctor II options.
Required Equipment
• Real time Teledyne LeCroy Oscillosc ope with at least 20 GHz bandwidth and sample rate of at
least 40 GS/s. The minimum recommended bandwidth for SAS 12Gbps is 25 GHz.
• QPHY-SAS3 (available on firmware 7.4.0.3 or later), SDA III, and Eye Doctor II options
Note: SDAIII is included on all SDA and DDA oscilloscope models
o The VirtualProbe option is required to perform de-embedding using the SDAIII
oscilloscope software
• SAS T est Fixture – Available from Wilder Technologies
o For a SAS-3 Target (Drive/Device): SAS Receptacle Adapter (SAS-TPA-R)
o For a SAS-3 Initiator (Host): SAS Plug Adapter (SAS-TPA-P)
o For Mini-SAS HD (Drive/Device): Mini-SAS HD Receptacle Adapter (MSASHD-TPA-R)

• 1 PC power supply – required to power the SAS test fixture and Device Under Test (DUT)
• SMA Cables ( Qty. 2)
o 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 fix tur es and the osc illos c ope (nom inal ly 6 inches each).
o 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
~10ps for 12Gbps)
• DC Blocks (Qty. 2) – <=10MHz to >=18GHz DC blocks (e.g Pasternack PE8210)
• MATLAB (either installed on the oscilloscope or on a separate PC) – required for the
SAS3_EYEOPENING script and Waveform Distortion Penalty test
• Matlab Complier Runtime 7.7 – required for the Waveform Distortion Penalty test, available for
download from teledynelecroy.com

USING QUALIPHY SAS3
QualiPHY SAS3 guides the user, step-by-step, through each of the tests in conformance with the T10
SAS-3 specification as described by the UNH-IOL SAS-3 Physical Layer Test suite. To do this, the
user must set up a test session.
Before beginning testing, users choose the test configuration they wish to run. There are nine pre-loaded
test configurations. They are:
• 12.0 Gbps Tx tests using Live (Acquisition) Data
• 12.0 Gbps Tx tests using Saved Data
• Demo of 12 Gbps Tx tests using Saved Data
• 1.5 Gbps Tx tests using Live (Acquisition) Data
• 1.5 Gbps Tx tests using Saved Data
• 3.0 Gbps Tx tests using Live (Acquisition) Data
• 3.0 Gbps Tx tests using Saved Data
• 6.0 Gbps Tx tests using Live (Acquisition) Data
• 6.0 Gbps Tx tests using Saved Data
These pre-loaded configurations provide quick and easy ways to begin compliance testing (see the
QPHY-SAS3 Test Configurations section for details on each configuration). If the user does not want
to run any of these configurations, they can create their own custom configuration (see the Creating
Custom Configurations section for details).
The pre-loaded configurations are set up to run all of the tests required for compliance. If this is not what
the user wants, the variables can be modified (see the QPHY-SAS3 Variables section of this manual).
The variables are pre-loaded with the standard settings for compliance testing; however, the user may
choose to create their own configuration with the variables set as desired.

QUALIPHY COMPLIANCE TEST PLATFORM
QualiPHY is Teledyne LeCroy’s 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 ge nerates complete, detailed reports.
The QualiPHY software application automates the test and report generation.

QPHY-SAS3 Software Option
Oscilloscope Option Key Installation
The required option k eys must be purchased to enable t he QPHY-SAS3 com pliance tests. If you do not
have the required option keys already call Teledyne LeCroy Customer Support to place an order and
receive the codes.
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 fr om the oscillosc ope or a host com puter. The first step is to install
QualiPHY. Please refer to the QualiPHY Operator’s Manual for installation instructions.
Teledyne LeCroy recommends running Qu aliPHY on an oscillosc ope 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 O sc illo scop e Sel ectio n (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 th e host com puter is c onnected t o th e sam e LAN as the oscillosc ope. If uns ure,
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.
922545 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-SAS3 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-SAS3 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 oscillos cope or from the desktop
icon if installed on a host computer.
3. From the QualiPHY main wind o w (as follows), select Standard, then SAS SAS3 from the popup menu (if not already selected). If you check the Pause on Failure box (circled) QualiPHY
prompts to retry the measure whenever a test fails.
