The new RTS 2701 from Pentek (Upper Saddle River, NJ) is a complete dual-channel transceiver recording and playback system in a standard 19-inch, rack-mount server chassis that can be placed in a rack or used on a desktop. As a powerful Windows XP workstation, the system allows customers to run their own applications plus a wide range of thirdparty software for signal analysis and post processing.

Building upon previous expertise in portable recording and playback systems, the RTS 2701 incorporates enhanced software features and a highly capable 7641-420 Software Defined Radio (SDR) module. It comprises wideband and narrowband digital downconverters that translate analog IF signals to baseband and digital upconverters that translate baseband digital signals to analog IF frequencies. They deliver a diverse set of bandwidths and sampling rates, with bandwidths as low as 8 kHz for voice bands, all the way up to 60 MHz for wideband radar. Input signals can be centered at IF frequencies as high as 300 MHz, so the RTS 2701 can handle a signal that is 40 MHz wide at 140 MHz just as easily as a signal 10 kHz wide at 21.4 MHz.

The RTS 2701 Recording and Playback System includes two 125 MHz A/Ds each generating data samples at 250 MB/sec. To match this rate, the system can record or playback both channels continuously in real-time at an aggregate sustained rate of 500 MB/sec. The standard version of the RTS 2701 comes with 5 terabytes of disk storage in a RAID (Redundant Array of Independent Disks) array. The system can be configured for RAID levels 0, 1, 5, 6, 10 and 50.
