Pentek has added the RTR 2654 26.5 GHz RF Sentinel Intelligent Signal Scanning rackmount recorder to its Talon signal recording and playback systems range.

RTR 2654 integrates the Pentek Talon Recording System with a 25.6 GHz RF tuner and Pentek's Sentinel intelligent signal scanning software. It automatically scans from 800 MHz to 26.5 GHz for signals of interest and can monitor or record bandwidths up to 500 MHz wide.

The data acquisition engine of the Talon RTR 2654 is a Pentek Model 78141 Jade transceiver module. One of its dual 3.2 GS/sec 12-bit A/D converters samples at a rate of 2.8 GS/sec. The Model 78141 is partnered 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. Any band of interest can be detected and the real-time recorder can capture and store hundreds of terabytes of data to disk.

Sentinel recorders are built on a Windows workstation with an Intel Core i7 processor and provide both a GUI and API to control the system. Systems support Pentek’s SystemFlow software for system control and turn-key operation. The SystemFlow software has been enhanced to include intelligent scanning and integrated control of the RF tuner and optional RF upconverter.

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 file format conversion.
