announced an addition to its popular family of Talon® signal recording systems,
the RTR 2623 6 GHz RF Sentinel™ Intelligent Signal Scanning portable, rugged
recorder. The RTR 2623 combines and exploits the power of a Pentek Talon
recording system with a fully integrated 6 GHz RF down converter. The Sentinel
capability adds intelligent signal scanning with real-time signal monitoring
and detection that is fully user configurable.  


Pentek - Rugged Sentinel intelligent signal scanning recorder

The Talon RTR 2623 is configured in a small footprint
portable package measuring only 16.0″ W x 6.9″ D x 13.0″ H and
weighing 30 pounds. The portable and rugged RTR 2623 recorder is a grab-and-go
portable recorder suitable for mobile military, security and government
intelligence (SIGINT, COMINT and ELINT) applications. The recorder performs in
nearly any mobile platform, even when subject to challenging levels of

A Pentek Model 78621 Cobalt® transceiver module serves as
the data acquisition engine of the Talon RTR 2623. Its 200 MHz 16-bit A/D
converter provides 86 dB of spurious-free dynamic range and 74 dB of SNR. A
digital downconverter (DDC) provides frequency zooming for signal bandwidths as
low as a few kHz. The Model 78621 is coupled to a 6 GHz RF tuner front end with
excellent dynamic range across its entire spectrum. 

Sentinel Intelligent Signal Scanning 
Sentinel users can scan the entire available spectrum or
select a region of interest. Selectable-resolution bandwidth allows for the
trading of sweep rate for a finer resolution and better dynamic range. RF
energy in each band of the scan is detected and presented in a waterfall

Any RF band can be selected for real-time monitoring or
recording. The Sentinel hardware resources are controlled through enhancements
to Talon’s SystemFlow® software package.  

“The RTR 2623 can reliably and intelligently capture
massive amounts of signal data in real-time, all within a compact, rugged and
highly portable package,” said Rodger Hosking, vice-president of Pentek. “The
deep storage capacity provides hours and hours of data capture and the
intuitive user interface outclasses other types of equipment on the market,” he

Ease of Operation 
Talon Sentinel recorders are built on a Windows 7
Professional workstation with an Intel Core i7 processor and provide both a GUI
(graphical user interface) and API (Application Programmer’s Interface)
to control the system. Systems are fully supported with Pentek’s SystemFlow®
software for system control and turn-key operation.  SystemFlow software has been enhanced to
include intelligent scanning and integrated control of the RF tuner and
optional RF upconverter. The software provides a GUI with point- and-click
configuration management and can store custom configurations for single-click
setup. It also includes a virtual oscilloscope, spectrum analyzer and
spectrogram to monitor signals before, during and after data collection.  

Post processing and analysis software tools like Matlab
can be installed directly on the Talon RTR 2623 platform. Data files are
recorded to the Windows native NTFS file system, which allows operators
immediate access to recordings without the need for any file format conversion.
