I have been using a SDR provided by Ettus Research (B205mini-i). This SDR uses a AD9364 transceiver. Ettus Research provide command definitions for their API which have been implemented in GNU Radio. I would like to extend what GNU Radio has but I am weak in the core functionality of the AD9364. The data sheet provides guidance but I need more to truly appreciate the transceiver. For instance, I would like to generate a 400 MHz CW signal on the transmitter port and I can not. It would be helpful to know what the AD6364 requires to do this so I can use the Ettus's API to achieve this. Are there any examples available for this or other examples for typical applications? I have not been able to find any application notes/white papers that are useful to me. Is there source for such items?
