1394 and AS5643 Bus Analyzer - FireSpy3432bT/3832bT

FireSpy® 3432bT/3832bT

The FireSpy3832bT and FireSpy3432bT bus analyzers are DapTechnology's latest 3-bus IEEE-1394 protocol analyzer. Based on the 4th generation FireSpy analyzer architecture the FireSpy3432bT/3832bT is the most advanced 1394 test equipments in the market. The FireSpy3x32bT 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 seamless integration of the SAE AS5643 protocol makes the FireSpy3432bT/3832bT the preferred tool for many Aerospace & Defense development tasks. DapTechnology has taken considerable efforts to fully support the AS5643 protocol in all major functional areas of the FireSpy3x32bT and continuously updates the analyzer functionality according to implementation requirements and ongoing standardization efforts.

4th Generation Hardware

In order to support multi-bus analysis more efficiently this new generation of 1394 bus analyzers has been completely re-architectured.

The FireSpy3432bT/3832bT has three 1394 nodes connected to three synchronized analysis engines. It is controlled by a dual core ARM processor running at 667MHz. Each node is connected to two 1394 ports. Two ports of each node are connected to LEMO connector.

The FireSpy3432bT/3832bT is equipped with 5 GB internal memory and extensive hardware filtering and trigger possibilities. The analyzer can be connected to a host computer using its USB3.0 interface. 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 to program your own control software.

FireDiagnostics Suite

The FireDiagnostics Suite is the most comprehensive collection of 1394 analysis, simulation and interface tools for a wide range of applications. Apart from well established and hardware assisted analyzer tools like Monitor, Recorder, Generator, Commander, Scriptor and Mil1394 Signal Monitor, the suite also offers a set of software tools designed to allow the integration of the FireSpy products in a wide variety of testing applications, as well as extend customization of its functionality beyond the baseline feature set provided by DapTechnology.

FireSuite API

The foundation for all software tools included in the FireDiagnostics Suite is formed by the Application Programming Interface (API). With its interfaces for a wide range of development environments using C/C++ or LabVIEWTM on WindowsTM Operating Systems, the application of FireSpy analyzers is extremely flexible. With its feature-rich function library, all hardware assisted analyzer tools like the Monitor and Recorder can be controlled as well as more low-level 1394 bus functions.

Protocol Support

A cornerstone of FireDiagnostics Suite functionality is the unparalleled level of support for high-level protocols. With IEEE-1394 being the basic data exchange mechanism application specific protocols for the PC & storage environment (IPv4, SBP2), consumer electronics (AV/C, HAVi), Automotive Infotainment (AMI-C), Industrial Imaging (IIDC) have been successfully deployed. In recent years AS5643 has been adopted for use within Aerospace and Defense and largely fueled the continuous growth of IEEE-1394.
