Bus Doctor SD/SDIO Analyzer

Compatible Operating Systems: Windows XP Professional or Windows 2000 Professional

The Bus Doctor™ RX SD/SDIO protocol analyzer allows
storage, silicon, and design engineers working with this
technology to capture, decode and analyze bus states,>
command tokens, and response tokens, and to measure
bus performance. The Bus Doctor’s interface is intuitive
and employs the Bus Doctor legendary easy-to-use GUI
software, making it the ideal analyzer for anyone developing
SD/SDIO hosts, devices, drivers, and consumer
electronic products.

The Bus Doctor RX from Finisar is a powerful, modular
bus-protocol analyzer with advanced features, such
as trace buffers as large as 4.6 GBs and 4 nanosecond
capture resolution. The Bus Doctor RX is able to analyze
SD/SDIO technology as well as other consumer electronics
and computing protocols.

The Beagle Data Center is the free software that is included with the Beagle USB 480 analyzer. Everyone is welcome to download this software from the Total Phase website to allow for easy collaboration through the sharing of capture data files.

By connecting a MC (Memory Card) Pod fitted with a SD/
MMC interposer board to a SD/SDIO system consisting
of a host and drive, the RX becomes a dedicated SD/SDIO
protocol analyzer. The analyzer operates at the SD/SDIO
data widths of x1 and x4 and supports filtering, capturing
and triggering of SD and SDIO events. The analyzer is
controlled by a Microsoft Windows™ PC through a USB
connection. Finisar’s powerful Bus Doctor Graphical
User Interface (GUI) CE 4.2 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 SD or SDIO information.
