LeCroy STX-460 SAS/SATA Protocol Test and Analysis for Serial ATAThe rich software and reconfigurable hardware core of the STX-460 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 STX-460 is configurable to individual user requirements and is field upgradeable, minimizing and preserving your test equipment investment. The STX-460 platform supports up to four full-duplex links at data rates up to 6 Gbps. The STX-460 can also be cascaded with other STX-460 and STX-431 units, increasing the number of physical links that can be monitored (up to 32 physical links) through a single GUI.
Expert Trigger and Filter options to pinpoint events of interest
The STX-460 features several customizable options for triggering and pre-filtering ensuring that relevant data is captured. Both the triggering and filtering capabilities can be accessed either through ‘Easy’ mode, which features simple ‘click to add’ functionality, or ‘Advanced’ mode which features a 24-level state sequencer with 1 IF and 3 ELSE-IF conditions per state. ‘Advanced’ mode also supports three independent timers and the ability to change pre-filters for each state. Trace/Buffer size as well as pre- and post-trigger capture is also definable.
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-460 Memory Upgrade
The STX-460’s Trace Buffer can be upgraded from the standard 4GB to 8GB.
