Using optimized IP core for Xilinx Virtex-6 FPGA, Cobalt® Model 52663 3U VPX Module is suited for mobile monitoring systems that must capture some or all of 1100 uplink and downlink signals in both upper and lower GSM bands. Unit accepts 4 analog inputs from external analog RF tuner, where GSM RF bands are down converted to IF frequency. IF signals are then digitized by 4 A/D converters and routed to 4 channelizer banks, which perform digital downconversion of all GSM channels to baseband.
