Pentek, Inc. introduced a new addition to the Talon® Series of recorders, the Model RTR 2742 4U 19 in. rackmount recorder. The Talon RTR 2742 is a turn-key record and playback system for ultra-wideband analog RF/IF signals. Using two 12-bit, 6.4 GHz A/D converters, this system can achieve sustained recording of 2.4 GHz bandwidth signals at rates up to 6 GB per second. It can be configured as a one- or two-channel system and can record real samples or complex I+Q digitally down-converted samples. 

Complemented by a 16-bit, 6.4 GHz D/A converter, the RTR 2742 is capable of playing back analog signal bandwidths up to 1.28 GHz. Built-in digital down- and up-converters provide flexible bandwidth and tuning frequency selection for both record and playback. 

“Many communications and radar applications operate across ultra-wideband frequencies. Now we can satisfy the many customers who need to digitize and record these signals with bandwidths as high as 2.4 GHz,” noted Rodger Hosking, vice-president at Pentek. “With the Talon RTR 2742, engineers can capture the whole spectrum in a single wideband channel, eliminating the need to break up the signal into smaller bands, covering adjacent slices of the spectrum,” he added.

The industrial grade 4U 19 in. rackmount chassis of the RTR 2742, with hot-swappable data drives, front-panel USB ports and I/O connectors on the rear panel, is optimized for cooling and ruggedized to operate in challenging environments. 

The RTR 2742 includes a 12-bit 6.4 GHz A/D that can be clocked at rates from 1.6 to 6 GHz in single-channel mode. Data can be truncated and packed as eight-bit samples, to support continuous recording up to the maximum sample rate. The D/A is capable of reproducing signals with up to 1.28 GHz of instantaneous bandwidth and includes a wide range of interpolations. The RTR 2742 provides up to 122 TB of front panel removable solid-state storage for hours of real-time, high-bandwidth signal recording.

Ease of Operation
All Talon recorders are built on a Microsoft Windows platform and include Pentek’s SystemFlow software, featuring a graphical user interface (GUI), the Signal Viewer and Application Programming Interface (API). 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. The Signal Viewer provides 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.
