Signal recordings are stored as files in the native Windows new technology file system (NTFS) format for immediate use by PCs and applications without the need for post-recording file conversion. "As complete recording systems, the Extreme Talon recorders are ideal for capturing a range of wideband analog signals for communications and radar systems," said Rodger Hosking, vice president of Pentek. "The RTX 2786 extends the advanced recorder technology developed for our commercial Talon products to extreme operating environments."
For the RTX 2786 chassis, Pentek selected MIL/AERO specialist Themis Computer. "Pentek's data acquisition and recording expertise, joined with our experience in ruggedized chassis development and cooling, now provides engineers a proven data collection and playback system for the harshest operating conditions," said Themis' director, Business Development, Bill Ripley.
The RTX 2786 digitizes and records multiple analog input channels using 200 MHz 16-bit ADCs. The system can capture up to 80 MHz of instantaneous bandwidth for IF signals ranging up to 700 MHz. Built in digital downconverters allow signals to be translated to baseband. These signals can be reproduced at their original IF frequency using the optional 800 MHz 16-bit DAC with built-in digital upconversion. The recording system supports sustained recording rates to 500 Mbytes/second from up to four data channels.
By using conduction-cooled circuit boards and solid-state drives, the RTX 2786 exhibits high immunity to temperature, shock and vibration. The drive array capacity can be as large as 1.92 TB and supports RAID levels 0 or 1. An optional data transfer unit (DTU) allows a user to add storage and provides a mechanism for the quick and easy replacement of data drives in the field.
The recorder's rugged ½ ATR 3U VPX chassis utilizes five D38999 circular connectors for 24 to 32 VDC power and digital I/O, and SMA connectors for analog inputs and outputs. Available I/O includes audio and VGA video, RS-232/422/485 serial, multiple USB 2.0 and dual Gigabit Ethernet connections.
Designed to be mounted on a cold plate for conduction cooling, the unit also has an optional shrouded heat sink for forced-air cooling.
The built-in Windows 7 Professional workstation with an Intel Core i7 processor gives the user total flexibility in routing data to various drives, networks and I/O channels. Also, the user can install post-processing and analysis tools on the system itself to operate on the recorded data. The RTX 2786 is fully supported with Pentek's SystemFlow software for system control and turn-key operation. The software provides a graphical user interface with point-and-click configuration management and can store custom configurations for single-click setup. The software also includes a virtual oscilloscope and signal analyzer to monitor signals before, during and after data collection.
The RTX 2786 can be controlled remotely through a network connection when operating in severe environments unsuitable for humans.
