QPHY-SAS3 Software Option

INTRODUCTION TO QUALIPHY SAS3

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 Series oscilloscope with at least 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 Oscilloscope 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

The VirtualProbe option is required to perform de-embedding using the SDAIII
oscilloscope software

• SAS Test Fixture – Available from Wilder Technologies

For a SAS-3 Target (Drive/Device): SAS Receptacle Adapter (SAS-TPA-R)

For a SAS-3 Initiator (Host): SAS Plug Adapter (SAS-TPA-P)

For Mini-SAS HD (Drive/Device): Mini-SAS HD Receptacle Adapter (MSASHD-TPA-R)

For Mini-SAS HD (Host): Mini-SAS HD Plug Adapter Right (MSASHD-TPAR-P) or Left
(MSASHD-TPAL-P)

• 1 PC power supply – required to power the SAS test fixture and Device Under Test (DUT)

• SMA Cables (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
~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
