The FireSpy422bT and FireSpy822bT bus analyzers are DapTechnology's latest single-bus IEEE-1394 protocol analyzers. Based on the 4th generation FireSpy analyzer architecture the FireSpy422bT/822bT is the most advanced 1394 test equipment in the market. They comprises a significantly more powerful on-board processor and improved connectivity to the host.

The seamless integration of the SAE AS5643 protocol makes the FireSpy422bT/822bT 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 FireSpy422bT/822bT and continuously updates the analyzer functionality according to implementation requirements and ongoing standardization efforts.

In order to to keep up with the growing data analysis needs this new generation of 1394 bus analyzers has been completely re-architectured.

The FireSpy422bT/822bT have a single 1394 node connected to one analysis engine. It are controlled by a dual core ARM processor running at 667MHz. The node is connected to three 1394 ports. All ports are connected to a 1394 bilingual connector in compliance with the 1394 standard.

The FireSpy3422bT/3822bT are equipped with 5 GB internal memory and extensive hardware filtering and trigger possibilities. The analyzer can be connected into a host computer using its PCIe x1 (or higher) 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.
