The V615 digital transceiver 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 can do contiguous recording at 2,000 MByte until running out of disk space. The transmitter can play the recorded baseband waveform of different bandwidth, 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 80 MHz. The DDC data is packetized in VITA-49 format with the accurate timestamps, synchronous to the external PPS signal. The DDC channel can be enabled and disabled on the fly to save the storage and bandwidth to the host computer. The embedded power meter monitors the power (dBFS) of the ADC inputs, allowing users to perform possibly analog gain control in the external front-end device, not included in the system.

The spectrum analyzer, including windowing, calculates the wide- band spectrum of the ADC data or the narrow-band spectrum of the DDC output data at the programmable update rate. The maximum hold helps to retain the information in the spectrum and the programmable threshold monitoring spectrum detects the spectral activities up-to 512 bins.

A development kit is available for the custom design. Users can insert custom-made cores to create even more advanced applications.
