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 downconverters (DDCs), the system is ideal for capturing the IF outputs of RF downconverters with bandwidths as high as 600 MHz. Selectable DDC tuning frequencies allow the RTR 2745 to accommodate a broad range of IF outputs.
"The RTR 2745 was designed to complement the wideband IF outputs of the latest RF downconverters," stated Chris Tojeira, product director of Recording Systems. "With high speed, high dynamic range A/Ds and D/As, this system is our first to provide extremely wide bandwidth recording with matching playback," he continued.
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 downconverter.
Two output channels with 2.8 GHz 16-bit D/As and matching digital upconverters (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 downconverters 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.
Pentek's SystemFlow Simulator software package simulates the SystemFlow® recording software, which is installed on all Talon® recording systems. You can download and install the free SystemFlow® Simulator to your desktop or laptop PC.
