The SPR870A 3U VPX Wideband Digital Receiver/Exciter module builds on abaco´s legacy of industry-leading digital receiver families and extending still further the growing ecosystem of abaco´s 3U VPX solutions. It features Xilinx Virtex-6 FPGA technology to enable its deployment in wideband signal acquisition and conversion applications such as radar ECM (Electronic Counter Measures), pulse intercept and analysis (ELINT) and RF (radio frequency) test applications.
Fully rugged and conduction-cooled, the SPR870A is capable of digitizing analog input signals from below 50 MHz upto 1.5 GHz, using a dual channel 10-bit ADC (analog to digital converter) and two 12-bit DAC (digital to analog converter), and re-creating analog output waveforms over a similar frequency range. An open source Xilinx Virtex-6 FPGA is provided for user-defined signal processing functions, giving greater capacity than previous generations. A second Virtex-6 provides a PCIe interface to the system controller. Other protocols, such as sRIO can be provided on request.
Legacy systems use carefully tuned analog components to determine key transmitter identification parameters such as instantaneous frequency, and modulation rate and the SPR870A allows these parameters to be measured using DSP techniques rather than analog circuits, making them much faster, more acurate and more flexible. Waveforms can now be stored as they are received, used as raw data to generate false returns, and played back on demand.
