Pentek have introduced an addition to the Talon Series of recorders, the Model RTR 2750 rugged rackmount recorder. This recorder, optimised for rugged operating environments increases the performance of the Talon Rackmount Series with twice the number of channels, over 50% more storage capacity, 25% faster sampling rates and nearly twice the sustained aggregate recording rate.

The RTR 2750 is a turnkey recording system in a single 4U rackmount chassis. It provides phase-coherent, synchronous recording of sixteen independent input channels at a sustained aggregate data rate up to 8GB/sec. Transient signals and radar pulses can be precisely captured through external gating and triggering inputs.

Each input channel includes a 250 MHz 16-bit A/D and an FPGA-based digital downconverter with independent tuning and programmable decimation from 2 to 65536 to capture RF signal bandwidths ranging from 3kHz to 100MHz. The RTR 2750 offers a storage capacity up to 61 TB, utilising up to 32 hot- swappable solid-state drives (SSDs) that can be easily removed or exchanged during a mission to retrieve recorded data extends.

“The RTR 2750 is the most size and space efficient of our recorders,” stated Chris Tojeira, product director of Recording Systems. “System cost is significantly reduced by doubling the channels in a 4U configuration and the sustained recording rate is double over our existing model,” he continued. The RTR 2750 is suitable for multi-channel radar, signal intelligence and communications applications, with the flexibility of common or independent signal tuning and bandwidth.

All Talon recorders are built on a Windows 7 Professional workstation and include Pentek’s SystemFlow software, featuring a GUI (graphical user interface), signal viewer and API (Application Programming Interface).

The GUI provides intuitive controls for out-of-the-box turn-key operation using point-and-click configuration management. Configurations are easily stored and recalled for single-click setup. User settings to configure data format for the signal viewer provide a virtual oscilloscope and spectrum analyser to monitor signals before, during and after data collection. The C-callable API allows users to integrate the recorder control into larger application systems. Enhancements to the GUI allow more efficient configuration of the recording channels.

The data format used for storage follows the NTFS standard, allowing users to remove drives from the instrument and read the data using standard Windows-based systems, eliminating the need for file format conversion.
