RapXG™ Quad-Port Network Record & Playback System

*This product is no longer recommended for new designs.

Real-time systems, such as electronic trading systems or radar track distribution, rely on the timely receipt of information for proper operation. The RapXG delivers scalable, high-performance packet capture and playback. The RapXG comes standard with essential features, such as accurate time synchronization, programmable 5-tuple filters, PCAP Next Generation file format, a highly efficient PCI Express Gen3 host, a user-friendly GUI, and a feature-rich API for record and playback functions.

Playback of recorded network data is a key feature of the RapXG systems. Instead of simply sending captured packets back onto the network, RapXG plays them back at the rate they were captured. Using hardware-controlled precision clocks and the recorded capture timestamp, the RapXG plays back network data to within 20ns of captured time. The RapXG card supports IRIG-A, B, and G time code to ensure precise time synchronization of network data. The time source is provided via a front panel SMA connector

The RapXG is available with a high-level application API and drivers for Linux. This allows application software to take advantage of the card’s capabilities through a C++ library and allows applications to modify card settings easily. Because the RapXG system is fully integrated with the popular Wireshark network protocol analyzer, it provides a powerful tool for engineers and managers to easily leverage their existing expertise, increasing efficiency in diagnosing network issues.
