New Spectrum Record and Playback Solution Supports up to 600 MHz of Bandwidth

Pentek has added the new Model RTR 2745 rugged rackmount recorder to its Talon series of recorders. The new recorder is optimized for rugged operating environments and can capture signals up to 3 GHz. This new model increases the bandwidth for record and playback of the Talon Rackmount Series with capability to capture and reproduce signal bandwidths up to 560 MHz.

The RTR 2745 is a turnkey, wideband recording and playback system that provides real-time capture of RF and IF signals. With two 3 GHz 14-bit A/D converters and built-in digital down-converters (DDCs), the system is ideal for capturing the IF outputs of RF down-converters with bandwidths as high as 600 MHz. Selectable DDC tuning frequencies allow the RTR 2745 to accommodate a broad range of IF outputs. With high speed, high dynamic range A/Ds and D/As, the system is Pentek’s first to provide extremely wide bandwidth recording with matching playback.

The DDCs provide a fixed decimation of 4 with selectable tuning frequencies to fs/2. This provides excellent flexibility when trying to match the IF of a selected wideband RF down-converter. Two output channels with 2.8 GHz 16-bit D/As and matching digital up-converters (DUCs) provide a fixed interpolation of 4 to allow for precise signal reproduction of recorded signals.

The 3 GHz A/Ds can operate without the digital down-converters to provide an extremely wide baseband capture. The system offers flexible sample rates ranging from 1.5 GHz to 3.0 GHz. The RTR 2745 offers a storage capacity up to 61 TB, utilizing up to 32 hot-swappable solid-state drives (SSDs) that can be easily removed or exchanged during a mission to retrieve recorded data.

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 analyzer 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. The SystemFlow Simulator software package simulates the SystemFlow recording software, which is installed on all Talon recording systems.
