OTTAWA, Ontario. Engineers at D-TA Systems Inc., released two new software radio solutions, dubbed RFvision-1 and RFvision-2, for performing signal activity detection, RF spectrum scanning, and real-time signal recording and playback.

The products are designed for applications such as signals intelligence (SIGINT), RF Spectrum Monitoring; electronic intelligence (ELINT); communications intelligence (COMINT), RF test and measurements; and arbitrary waveform generation.

The RFvision-1 has frequency coverage from 20 MHz to 6 GHz with a bandwidth of 40 MHz. The RFvision-2 (pictured) delivers frequency coverage is from 500 MHz to 26.5 GHz with a bandwidth of 500 MHz. Each product offers real-time recording and playback of the selected signal. Either one can be controlled from a user’s PC that uses a D-TA-supplied GUI.

The products’ real-time recording and playback of almost 2 GBytes per second is possible due to D-TA’s 10 gigabit sensor processing technology,” says Dipak Roy, Chairman of D-TA Systems. “We have adapted the 10 gigabit network technology for sensor processing.”

Other key features RF signal activity detection; include, high-precision data converters; and programmable DDC based processing bandwidth selection.

We’ve implemented the whole thing using FPGA technology, Roy says. It is faster than most computer buses and also is free of the digital noise associated with a computer bus. The technology also uses optical fibers to transfer data, over long distances if required. The device’s throughput rate can be increased by adding more fibers -- multiple fibers also can be synchronized.

This processing architecture is also sensor independent, remaining the same no matter what type sensor is being processed.

The D-TA devices also can be quickly deployed with little customization, Roy says. For 90 percent of the solutions all the customer has to do is write the application code, he adds. “They can just drop the server into the network – making sensor to network a reality.”
