Pentek’s Talon RTR 2749 is a turnkey system used for recording high-bandwidth signals. It uses 12-bit, 3,6 GHz A-D converters and can provide sustained recording rates up to 3,2 GBps. It can be configured as a one- or two-channel system and can record sampled data, packed as 8-bit-wide consecutive samples, or as 16-bit-wide consecutive samples (12-bit digitised samples residing in the 12 MSBs of the 16-bit word.)
The system uses Pentek’s high-powered Virtex-6-based Cobalt boards that provide the data streaming engine for the high-speed A-D converters. Channel and packing modes as well as gate and trigger settings are among the GUI-selectable system parameters, providing complete control over the recording system. Optional GPS time and position stamping allows the user to capture this critical information in the header of each data file.
The RTR 2749 includes SystemFlow recording software which features a Windows-based GUI that provides a simple means to configure and control the system. Custom configurations can be stored as profiles and later loaded when needed, allowing the user to select preconfigured settings with a single click.
SystemFlow also includes signal viewing and analysis tools that allow the user to monitor the signal prior to, during and after a recording session. These tools include a virtual oscilloscope and a virtual spectrum analyser.
Built on a Windows 7 Professional workstation, the RTR 2749 allows the user to install post-processing and analysis tools to operate on the recorded data. The system records data to the native NTFS file system that provides immediate access to the recorded data.
Data can be offloaded via two gigabit Ethernet ports, six USB 2.0 ports or two eSATA ports. Additionally, data can be copied to optical disk, using the 8X double layer DVD±R/RW drive.
Because SSDs operate reliably under conditions of vibration and shock, the RTR 2749 performs well in ground, shipborne and airborne environments. The 40 hot-swappable SSDs provide storage capacity of up to 20 TB. The drives can be easily removed or exchanged during or after a mission to retrieve recorded data.
The system is configured in a 4U 19” rugged rackmount chassis, with hot-swappable data drives, front panel USB ports and I/O connectors on the rear panel.
Systems are scalable to accommodate multiple chassis to increase channel counts and aggregate data rates. All recorder chassis are connected via Ethernet and can be controlled from a single GUI either locally or from a remote PC. Multiple RAID levels, including 0, 1, 5, 6, 10 and 50, provide a choice for the required level of redundancy.
