Rackmount recorders achieve 4GB/s playback rates

Achieving 4GB/s aggregate recording and playback rates, the RTR 2728 and RTR 2748 rackmount recorders signal an expansion of Pentek's Talon family of turnkey recording systems. Designed to operate as complete recording systems, the recorders reproduce and record wideband IF signals at sample rates up to 1 GSamples/sec.

Built on a Windows 7 Professional workstation with an Intel Core I7 processor, the recorders provide both a GUI (graphical user interface) and API (application programmer’s interface) to control the system. Users can monitor and analyze signals prior to, during and after a recording with the provided signal analysis tools. Data files include time stamping as well as recording parameters and optional GPS information. Files are stored in the native Windows NTFS (new technology file system) format, eliminating the need for file conversion. Files can also be transferred from the system through gigabit Ethernet, USB ports or written to optical disks using the built-in 8X double layer DVD±R/RW drive. The recorder’s SSDs are configured to support numerous RAID levels giving the user many options to balance performance versus failsafe trade-offs. They are hot-swappable and can be easily removed or exchanged during or after a mission to retrieve recorded data.

Both recording systems use Pentek’s high powered Virtex-6-based Cobalt boards that provide the data streaming engine for the high-speed A/D and D/A converters. A built-in synchronization module is provided to allow for multi-channel phase-coherent operation. The rackmount system is scalable to accommodate multiple chassis for more channels and higher aggregate data rates.

Supporting software includes the Pentek SystemFlow, featuring a Windows-based GUI (Graphical User Interface) that provides a simple and intuitive means to configure and control the system.

According to Rodger Hosking, vice president of Pentek, “The new Talon recording systems have the ability to capture and reproduce signal bandwidths approaching 500 MHz. The recorded signals can be reproduced to replicate live sensor equipment or receivers in the field. Today’s higher-precision converters require more storage for long flights or experiments. The advanced SSDs we use in our ruggedized recorders not only add capacity, but they also keep up with the very high data rates. For example, the rackmount system can record up to 5.3 hours of contiguous data without interruption. And, both recorders operate flawlessly under shock and vibration, making them ideal for severe environments."

With pricing starting at $49,995, delivery is 8-10 weeks ARO for all models. Options are available for the number of recording and playback channels, storage capacity, and GPS time and position stamping.
