24.3.3. FireSpy 3852
The FireSpy385x bus analyzer is world’s only PCI –based multichannel FireWire bus analyzer. Based on
the industry leading FireSpy810 architecture the FireSpy385x is the most advanced IEEE 1394 test
equipment in the market. The FireSpy385x in fact
combines three FireSpy analyzers in one single instrument. It comprises a significantly more powerful
on-board processor and improved connectivity to the host.
The PCI format takes flexibility to a higher level. This solution enables users to install the FireSpy
hardware in any PC that has at least one PCI slot available. This allows for installation of the FireSpy in
developers existing PC’s or installing the analyzer in a rugged field service laptop or lunchbox computer.
The FireSpy385x has three 1394 nodes connected to three synchronized analyzer engines. They are
controlled by an onboard RISC processor running at 400 MHz.Two ports of each node are connected to a
circular LEMO connector and include active transformer coupling
The FireSpy385x is equipped with 1 GByte memory and extensive hardware filtering and trigger
capabilities. On the host you can control the FireSpy using a graphical user interface to analyze and
display the bus traffic in a user-friendly way, or you can use the API and program your own control
software.
The seamless integration of the SAE AS5643 protocol makes the FireSpy385x the preferred tool for many
Aerospace & Defense development tasks. DapTechnology has taken considerable efforts to fully support
the SAE AS5643 protocol in all major functional areas of the FireSpy385x and continuously updates the
analyzer functionality according to implementation requirements and ongoing standardization efforts.
