* \brief signal source for Analog Devices front-end AD9361 connected directly
|
|
* to FPGA accelerators.
|
|
* This source implements only the AD9361 control. It is NOT compatible with
|
|
* conventional SDR acquisition and tracking blocks.
|
|
* Please use the fmcomms2 source if conventional SDR acquisition and tracking
|
|
* is selected in the configuration file.
