Overview:
The STX 460 protocol analyzer is a one solution for SAS and SATA protocol analysis and interfaces to a notebook or PC host via simple USB or Ethernet connectivity. Supporting both 1.5, 3 and 6Gbps technology decoding and analyzing the captured traffic SATA and SAS protocol streams for immediate analysis or fault and problem identification. The STX 460 has auto speed detection for selection of the 1.5 or 3 and 6Gbps SATA or
SAS data rates


Data capture:

The STX 460 has the ability to capture all frames transmitted. The system also allows the user to maximise the use of trace memory by excluding or filtering traffic that may not be of interest. Including, XXXX Fillers, IDLES, SATA_Cont. and SATA_Sync. The system will allow the use to Truncate data payloads for trace management.

Trace view display (Click image below for larger screenshot) :
The STX user interface runs on a standard Windows PC providing choice in the selection of host platform. Host platforms can be upgraded as PC specifications evolve without impacting
investment in test equipment. Host connections can be established through the STX platform’s standard USB and Ethernet ports, making it easy to find a compatible interface and facilitating
access within your network.
Advanced Mode Triggering:
The STX 460 has comprehensive triggering features. Manual triggering using an on screen start/stop button. Automatic triggering using the external trigger event connector. The system allows the user to define a trigger position that can be at the start, end or at any position within the captured trace. Allow the users to view trace traffic pre or post the problem or events. The STX application software provides two modes for control of the
capture (filter) and trigger sequences. In the Easy Mode, an extensive list of pre-defined triggers and filters are provided for quick and simple execution of traffic captures. This mode is suitable for most common tasks. For more complex tasks, an Advanced Mode interface is provided, which gives the user a powerful, programmatic approach to
controlling the capture/trigger process. This mode provides 24 sequencer states, including timers, counters, and IF, ELSE-IF, and GO-TO conditional logic.
Trigger sequencer logic (Click image below for larger screenshot) :
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.
Statistical reports (Click images below for larger screenshots) :
A wide range of statistical reports and data views helps the user to analyze complex bus traffic patterns. Reports include :- Performance, Primitive, SAS Address, SCSI command
statistics and more.


Data Views:
This is a simple and easy to understand Tree Structure showing a logical organisation of Frames with the in built ability to expand individual fields.
OOB Waveform and Sequences are also a display feature. All these different views can be simultaneously displayed on screen allowing fast and easy interpretation of the captured Trace traffic. A spreadsheet display of decoded data fields can be exported to text or
Microsoft Excel format
OOB Waveform display:
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. This sequence is also represented in the word and packet view
formats. The user can easily view the burst and idle times for each event, and can select cursors
in both views to obtain delta times between events.
Pattern generation:
The STX Series provides a pattern generator utility, which allows bit-level control over data sent out on the wire. The pattern generator is a standard feature, provided on all STX models. Test patterns are generated through simple text files. Link data can be specified in K/D, Hex, or text formats. Link speed and scrambling functions can be controlled by the user, allowing the capability to generate both compliant and non-compliant bit streams. Several sample files are provided in the STX software for both SATA and SAS applications.



Host initiator emulation - Option:

The STX Series provides integrated initiator emulation for both SAS and SATA. High level commands can be easily defined and sent to target devices through a series of convenient pull-down menus, eliminating the need to resort to low-level programming. All traffic on the bus, including traffic generated by the STX and returned traffic from the device under test, is captured and displayed in the intuitive Catalyst trace format. Various error injection capabilities allow for full characterization of target devices and related error handling
capabilities. Looping, iteration, and a wealth of conditional statements provide for precise control of the emulator scripting routines. Link layer exchanges, link initialization using Out of Band (OOB) signaling, handshaking, and retry conditions are handled automatically, allowing test files to be generated quickly and easily.

Initiator Emulator Features & Controls
:

Convenient drop-down menus for command selection
Conditional logic for control of initiator sequence
Control of ALIGN transmission period
Primitive response timeout settings
User-defined data blocks for write operations
Task attribute selections
Error injection capabilities
Concurrent operation with analyzer




Device target emulation- Option

The STX Series provides integrated target emulation for both SAS and
SATA. The target emulator simulates the behavior of a SAS or SATA
device, including normal and abnormal behaviors. The emulator can be
configured for most mode page settings, capacities, and other critical
parameters, such as payload size, block size, ALIGN transmission time,
and access time. Error conditions can be emulated for response frames,
data frames, and XFER RDY frames. SAS commands supported include SSP and
SMP.

Target Emulator Features & Controls:
Definable mode page settings
Support for SSP and SMP commands
Full R_RDY control for buffer starvation
Access time control
Pre-designated error responses
Control of ALIGN transmission period
