LeCroy STX-131 SATA Protocol Test and Analysis for Serial Attached SCSIThe rich software and reconfigurable hardware core of the STX-131 enables users to perform a variety of sophisticated functions using a single, compact hardware package. This flexibility allows users to gain visibility and exert precise control over every aspect of the SAS and SATA architectures, thus providing the complete solution for Serial Attached SCSI and Serial ATA testing. Flexible and Extendable Verification Platform
The LeCroy STX-131 is configurable to individual user requirements and is field upgradeable, minimizing and preserving your test equipment investment. The STX-131 platform supports one full-duplex link at data rates up to 3 Gbps
Custom Data Displays for Easier Analysis of Protocol Traffic
Captured traces can be displayed in a variety of ways to suit the analysis being performed. The Packet View decodes captured events and displays them with accurate time of occurrence and duration information. Link layer, transport layer, and application layer views are provided, using color to differentiate between each layer. Layers can be hidden, collapsed or expanded to vary the amount of data, from a meaningful summary to bit-level detail. The Spreadsheet View provides an organized chronological view of all bus events. Detailed information is provided on time stamps, duration, direction, source and destination addresses, command and/or picker contents. The Text and Column Views provide an intuitive understanding of frames, primitives, and other events, and includes at-a-glance addressing and summary indications of bus activity. The OOB Waveform View indicates OOB activities in waveform-like display. The captured OOB sequence is displayed in a graphical format, which represents the time relationships between the various OOB events. 
Post Processing - Find the Issues Fast
Statistical summaries of the trace data are available at the click of a mouse button, and provide counts, timing, and performance information. Jumping from the statistical summaries to specific events is a simple mouse click, eliminating the need to search traces for events that may or may not be present. Comprehensive post-capture filters and search capabilities display relevant events with the detail necessary to isolate and solve protocol issues. When issues are found, bookmarks can be inserted in the trace to allow comments to be embedded for future reference.
STX-131 Memory Upgrade
The STX-131’s Trace Buffer can be upgraded from the standard 512MB to 1GB.
STX-131 SATA Compliance Upgrade
The STX features an option for the integrated Serial ATA (SATA) Compliance Test Suite. Testing includes support for disk drives, including HDD, SSD, and ATAPI drives, as well as SATA Hosts. Areas covered for testing are Asynchronous Signal Recovery (ASR), Interface Power Management (IPM), General Test Requirements (GTR), Software Settings Preservation (SSP), and Native Command Queuing (NCQ). These tests are informative and meant to assist in the development and debug process. The SATA Compliance Test Suite is very easy to run and can be included in regression testing. After the test suite has completed running, a report is generated with test results. Traces are saved for all tests such that the end-user can verify potential design issues. The SATA Compliance Test Suite can either be added as an option for the STX-131 or comes included in the Host (for testing Devices) and Device (for testing Hosts) Emulators. |
