High-Speed, Real-Time Recording for Extremely Wide Bandwidth Signals

A ready-to-run, PC-based recorder includes a complete PC workstation running Windows XP, housed in a rackmount 4U chassis. The Model RTS 2711 Real-Time Data Recording Instrument from Pentek incorporates an extremely high-speed architecture that allows simultaneous digitizing and recording of two signals at sampling rates of 500 Megasamples/sec. Since the system handles input signal frequencies up to 750 MHz, it is well suited for development and field testing in a broad range of wideband signal applications including UAVs, telemetry, communication and radar. 

In addition to its unusually high data rates, the Model RTS 2711 has a total of 4 terabytes of RAID storage to record arriving signals. The storage is actually configured as two 2-terabyte arrays with each of the arrays assigned to one of the A/D channels. With each of the two channels running at its full rate of 500 Megasamples/sec, users can record signals continuously for an hour. And because the Model 2711 is a complete turn-key instrument, they don’t need to do any programming or write any software—they can start recording immediately.

The RTS 2711 records data directly in NTFS (new technology file system) format. This means that as soon as recordings are laid down on the RAID array hard disks, they are immediately available to any Windows application for analysis or post-processing. A number of competing instruments use a proprietary file system for recording. In order to open these files in Windows applications, such as signal analysis tools like MATLAB and others, the files must first be converted to a Windows-compatible file format. This conversion can often take many times longer than the actual duration of the recording. 

The RTS 2711 is easy to use due to its SystemFlow software package based on a client/server architecture and delivered with every RTS instrument. SystemFlow includes several key components. The Graphical User Interface (GUI) provides the user with a control interface for the recording instrument and an intuitive means for setting up system parameters. The Signal Viewer includes two companion analysis tools: a virtual oscilloscope and a virtual spectrum analyzer so users can monitor the signal prior to, during and after a recording session. Together, these elements of SystemFlow greatly simplify operation. In addition, SystemFlow includes an Applications Programming Interface (API), which allows users to integrate control of the RTS instrument into a larger system application. Pricing starts at $58,995.
