Verify and debug your SAS devices faster and more easily

Keysight Technologies, Inc. Serial Attached SCSI-3 (SAS-3) compliance test software for Infiniium Series oscilloscopes provides you with a fast and easy way to validate and debug your SAS 1.5, 3.0, 6.0 and 12.0 Gbps silicon, host bus adapter, initiator, high-density disk drive or enclosure backplane. It also supports automated SAS out-of-band (OOB) and loop back signal tests with the 81134A pattern generator and N4903B BERT with Option 002. The SAS compliance test software allows you to automatically execute SAS electrical checklist tests at each of the IT and CT interface points and displays the results in a flexible report format. In addition to the measurement data, the report provides a margin analysis that shows how closely your device passed or failed each test.

SAS-3 software saves you time

The SAS-3 compliance test software saves you time by setting the stage for automatic execution of SAS electrical tests. Part of the difficulty of performing electrical tests for SAS is connecting the oscilloscope to the target device, configuring the scope’s measurement system for compliance testing, issuing the proper commands to perform the tests and then analyzing the measured results by comparing them to limits published in the specification. The SAS electrical test software does much of this work for you. In addition, if you discover a problem with your device, debug tools in the scope are available to aid in root-cause analysis.

Easy test definition

The SAS-3 compliance test software extends the ease-of-use advantages of Keysight’s Infiniium Series oscilloscopes to testing SAS designs. The Keysight automated test engine walks you quickly through the steps required to define the tests, set up the tests, perform the tests, and view the test results. You can select a category of tests all at once, or specify individual tests. The user interface is oriented to minimize unnecessary reconnections, which saves time and minimizes the potential for operator error. You can save tests and configurations as project files and recall them later for quick testing and review of previous test results. Straightforward menus let you perform tests with a minimum of mouse clicks.

Configurability and guided connections

The SAS-3 compliance test software provides flexibility in your test setup. When the tests you select require it, the software guides you to make connection changes with hookup dia­grams. The SAS electrical test soft­ware provides you with user-defined controls for critical test parameters, such as interface, line baud rate and number of unit intervals (UI) desired for the test group.

Reports with margin analysis

In addition to providing you with measurement results, the SAS-3 compliance test software provides a report format that shows you not only where your product passes or fails, but also reports how close you are to the limits specified for a particular test assertion. You select the margin test report parameter, which means you can specify the level at which warnings are issued to alert you to the electrical tests where your product is operation close to the official test limit defined by the specification for a given test assertion.

Thorough performance reporting

The SAS-3 compliance test software generates thorough reports that not only capture the performance and status of the device under test, but capture the screen shots of your most significant measurements for your documentation and evaluation.

Measurement requirements

To use the SAS-3 compliance test software you will need a Keysight Infiniium Series oscilloscope with at least 12-GHz of analog, real-time bandwidth. MATLAB license is required to run the WDP tests. In order to use the SAS-3 compliance test software for compliance validation, your SAS chipset will need to be able to source the required compliance jitter tolerance pattern (CJTPAT or jitter tolerance pattern (JTPAT), SCRAMBLE_0 pattern and long random pattern (e.g. IDLE Dwords, PRBS 15 , etc.). The SCSI software command language provides a method for enabling these PHY test patterns in most chipsets by sending a “send diagnostic” command through a protocol-specific diagnostic page (see “Section 4.2 Phy test functions” of the SAS-3 Specification for details).
