Hi all,
We are currently trying to implement an RF Radar with the USRP 2954R & PXIe-1071 as a part of our Master Project.
As a step to learn FPGA Programming on the USRP device, we intend to use the internal FPGA for the generation of the chirp signal and for custom DSP.
Q1) We decided to modify the NI Simple Streaming Example to suit the application. We already know, that our code must be inserted in Rx & Tx core.vi in between the stream FIFO & DDC/DUC.
In this example, the signal generation (single tone) is done on the host side. But, what if we want to generate the signal on the FPGA and just trigger the sending of this generated signal on the host side?
Q2) Could you please explain the interaction between the standard high and low level USRP functions (Eg: attached) and the standard FPGA program in the example. And when we change the FPGA program, can we still use these USRP functions?
Q3) How could we modify the example Streaming host program to fit to our application (RF Radar).
Thanking you in advance.
