UPPER SADDLE RIVER, N.J. – Pentek Inc. in Upper Saddle River, N.J., is introducing the RTR 2654 26.5 GHz RF Sentinel intelligent signal scanning rackmount data recorder for military, security, and government signals, communications, and electronic intelligence applications.
The RTR 2654 combines a Pentek Talon recording system with a 25.6 GHz RF tuner and Pentek's Sentinel intelligent signal scanning software for automatic scans of the RF spectrum from 800 MHz to 26.5 GHz for signals of interest and monitor or record bandwidths as wide as 500 MHz.
A Pentek Model 78141 Jade transceiver module serves as the data acquisition engine of the Talon RTR 2654. One of its dual 3.2 gigasamples per second 12-bit A/D converters operates at a sample rate of 2.8 gigasamples per second.
The model 78141 rackmount system is coupled to the 500 MHz bandwidth IF output signal of a 6 GHz RF tuner front end. A digital downconverter (DDC) in the model 78141 provides frequency zooming for signal bandwidth steps of 500, 280, or 140 MHz.
The Sentinel recorder provides automated signal monitoring and detection. The user specifies a start and stop frequency for the scan, covering any range between 800 MHz and 26.5 GHz. The RF tuner and DDC step across the scan range in consecutive bands, each programmable up to 500 MHz in width for signals intelligence. Threshold RF energy in each band can be detected to trigger creation of a waterfall spectrum display over the entire scan.
Users can choose any band for continuous real-time monitoring and recording. In addition to manual band selection, a recording can be automatically started during a scan by configuring signal strength threshold levels to trigger a recording of the detected band. Once a signal of interest is detected, the real-time recorder can capture and store hundreds of terabytes of data to disk, allowing users to store data spanning multiple days.
Sentinel recorders are built on a Windows workstation with an Intel Core i7 processor and provide a graphical user interface and application programmer interface to control the system.

Post processing and analysis software tools like Matlab can be installed on the Talon RTR 2654 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.
