LeCroy Corp. has extended its 6Gb/s-capable SAS and serial ATA protocol verification products with the STX M6-1, an ultraportable single-port platform available in either a protocol analyzer or error injector models.

Measuring 15.9mm x 3.5mm x 22.9mm and weighing in at 0.77kg, the STX M6-1 systems are compact units that fit easily into a corner of a brief case or backpack. Operating at 1.5-, 3- or 6Gb/s SAS or serial ATA data rates, and available with 2- or 4GB of recording memory, STX M6-1 offers protocol analysis or error injection capability at price points within reach of every budget.

STX M6-1 systems come standard with both USB and GbE interface ports for maximum flexibility in connecting to the host PC. The versatile GbE port can be used for either local or remote network connectivity. STX M6-1 systems can be linked together in cascade configurations to provide additional recording channel capacity, or used in tandem to combine simultaneous error injection and trace capture/analysis capabilities (requires multiple STX M6-1 units, at least one licensed as a protocol analyzer and at least one as an error injector).

STX M6-1 models are software-compatible with the LeCroy SAS/SATA Protocol Suite and offer the same features as the other products in the LeCroy SAS/SATA product line. The analyzer software offers an intuitive GUI combining easy setup with flexible traffic analysis views including spreadsheet, text, column, waveform and packet views. The protocol application layer can be analyzed with the packet view, which logically assembles frames and primitives that are part of specific SAS or SATA commands. Utilizing the packet view, one can quickly see the completion status of any command, which is especially useful in addressing system-level debug challenges. Statistical reports provide event and error counts, as well as performance metrics, that give users a snapshot into captured traces and rapid access to items of interest.

The STX M6-1 data capture capabilities include Easy Mode triggering to provide engineers with the ability to capture precise traffic conditions such as timing between events or changes in link state. Using Easy Mode, powerful trigger conditions can be set up quickly and easily through very straightforward, easily understood drop-down menu selections.

The STX M6-1 InFusion model performs as a standalone 1.5-, 3-, 6Gb/s version of the LeCroy InFusion Error Injector and Traffic Modifier, enabling engineers to verify error recovery characteristics of their designs. An easy-to-use pop-up menu interface allows the creation of customized test scenarios in just minutes. One can program on-the-fly modifications to any field within any frame, as the data moves across the link. Any primitive or data pattern can be intercepted and changed to a different user specified pattern. Examples include support for changing DWORD values, disconnecting links, and forcing various conditions such as a CRC error or running disparity errors. This enables unprecedented corner case modification of SAS and serial ATA traffic which is especially useful during the final test and integration cycles.
