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.
