Pentek's Ruggedized Portable RF/IF Signal Recording and Playback Instrument for Vehicle, Ship and Aircraft Applications

  • Digitizes, records, and reproduces up to four 80 MHz bandwidth signals
  • Provides up to 4 Terabytes of rugged, hot-swappable RAID solid-state storage
  • Portable shock-resistant housing includes complete Windows 7 workstation
  • Eliminates need for separate oscilloscope or spectrum analyzer
Pentek, Inc., today released a rugged, portable, multiband recording and playback system for high-bandwidth IF and RF signals. The RTR 2726, latest in Pentek's turnkey Talon" recorder family, is a complete workstation, data acquisition, and solid-state RAID recording system in a box for the capture and playback of signals up to 700 MHz in shock- and vibration-prone environments such as vehicles, ships, and aircraft.

The RTR 2726 is Pentek's second-generation in portable recording devices, but the first to use the popular Cobalt" series of software radio modules. "Customers with our first-generation RTS 2721 were using it in flight applications and asked for an upgrade to solid-state disk drives for tougher environments," said Rodger Hosking, vice president of Pentek. "We went much further, increasing signal frequency and bandwidth, and nearly tripling the recording speeds."

The system includes built-in digital up- and down-converters, with record channels offering 16-bit, 200 MHz ADCs and playback channels offering 16-bit, 800 MHz DACs. It can stream data to and from storage at sustained data rates of 1600 Mbytes/second, allowing the RTR 2726 to support four channels of record and/or playback in a variety of configurations. Storage consists of eight hot-swappable solid-state disk drives in a RAID configuration with up to 4 TB in total capacity.

Data files include time stamping as well as recording parameters and optional GPS information. They are stored in the native Windows NTFS format, allowing drive units to be read by other PCs without the need for extensive file conversion. Files can also be downloaded from the system through Ethernet, USB ports, eSATA ports or written to optical disks using the built-in 8X double layer DVD±R/RW drive.
