Overview:
The STX 131 interfaces to a notebook or PC host via simple USB port connectivity. Supporting both 1.5 and 3Gbps technology decoding and analysing the captured traffic SATA and SAS protocol streams for immediate analysis or fault and problem identification.
The STX has auto speed detection for selection of the 1.5 or 2Gbps data rates


Data capture:

The STX 131 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.

Packet view display:


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.

Triggering:
The STX 131 has comprehensive triggering features, manual using an on screen start/stop button. Automatic triggering using the external trigger event connector. Manual mode by using a "snap shot" mode (record until a predefined buffer size is reached). 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.


Statistical reports:

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.
General view 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.

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.
