The members of the converter product family are based on the same
digital back-end base structure. We offer two basic conversion front-
end structure for wide-band and channelised applications.
Matlab based time and frequency domain analiser toolOpen application Programming Interface (API) and sample code areavailable for developers

In wide-band the samples are available trough a FIFO for the
FPGA/DSP processing elements
In narrow-band (channelised) version DDC/DUC chips are used for
selecting the required channel and reduce the bandwidth
