FPGA-based 3U VPX DSP module with on-board A/D and D/A converters introduced by GE for electronic warfare applications
CHARLOTTESVILLE, Va., 2 March 2011. GE Intelligent Platforms in Charlottesville, Va., is introducing the SPR870A 3U VPX wideband digital receiver and exciter module for wideband signal-acquisition and -conversion applications such as radar electronic counter measures (ECM), pulse intercept and analysis electronic intelligence, and RF test and measurement.
"Legacy systems use carefully tuned analog components to determine key transmitter identification parameters such as instantaneous frequency, and modulation rate," McKeel explains. "The SPR870A allows these parameters to be measured using DSP techniques rather than analog circuits, making them much faster, more accurate and more flexible. Waveforms can be stored as they are received, used as raw data to generate false returns, and played back on demand."
The rugged and conduction-cooled SPR870A digitizes analog input signals from below 50 MHz to over 1.5 GHz, using a dual channel 10-bit A/D converter and two 12-bit D/A converters, and (re)creating analog output waveforms over a similar frequency range.
