BUS DOCTOR? SATA ANALYZER
Protocol, Timing & Statistical Analysis Modular Bus Protocol Analyzer for 1.5 and 3.0 Gb/s Serial ATA OVERVIEW
Serial ATA (SATA) is an evolutionary replacement for the Parallel ATA physical storage interface. Offering scalability and easier configuration than its parallel predecessor, SATA products such as hard drive are already available in the market. CDs, DVDs, and tape drives will be the next devices to benefit from SATA technology. By using a SATA protocol analyzer, storage product manufacturers can reduce their development times and improve their delivery times.
PRODUCT DESCRIPTION
The Bus Doctor? RX from Finisar is a powerful modular bus protocol Analyzer. With advanced features such as large trace buffers and 4 nanosecond capture resolution, the RX is a unique platform able to analyze SATA technology. By connecting a SATA Pod to a RX, the RX becomes a dedicated SATA protocol Analyzer. The Analyzer operates at line rate up to 3.0 Gb/s. There is also support for SSC (Spread Spectrum Clocking), Serial ATA-II Extensions and ATAPI. The Analyzer is controlled by a Microsoft Windows? PC through a USB connection; Finisar?s powerful Bus Doctor Graphical User Interface (GUI) software runs on the PC. The software provides an easy-to-use interface that allows engineers to configure the instrument and to view and analyze captured SATA traffic. High-level dialogs provide for the quick creation of powerful triggers and pre- and post-capture filters. These filters allow engineers to home in, and capture and analyze only those events and sequences of interest. One can filter on a Primitive (e.g. ALIGN), FIS (e.g. FIS 39 - DMA ACTIVATE) or Error (e.g. OOB) in either the host to device or device to host direction. The powerful trigger sequencer has 12 levels, including 2 timer and 2 counter levels. This allows for triggering on such things as FIS Types, Primitives and ATAPI commands. Triggers may also be setup for a variety of hardware and software errors. Once data is captured, the software simplifies analysis by organizing and grouping the captured bus data into different displays.
