The V616 digital transceiver from Innovative Integration (Camarillo, CA) supports one or two plug-in modules, each featuring four independent channels of DDC, two DUC, and one spectrum analyzer embedded in the Xilinx Virtex-6 FPGA. It allows users to monitor the wide-band or narrow-band spectrum and record the data directly from the ADCs or down-convert the channels modulated on the IF band. The embedded PC supports contiguous recording at 2,000 MBytes until running out of disk space. The transmitter can play a recorded baseband waveform of independent bandwidth, and up-convert and modulate it on the IF band on the DACs. Each DDC/DUC has its own programmable tuner, programmable low-pass filtering, gain control, and decimation/interpolation setting, supporting independent channel bandwidths up to 100 MHz.
