One good place to check for how to operate with RFNoC is the source file " multi_usrp_rfnoc.cpp <https://github.com/EttusResearch/uhd/blob/master/host/lib/usrp/multi_usrp_rfnoc.cpp>". Under the hood, the multi_usrp object used by most users for a stock FPGA image implements all functionality using RFNoC API calls for any of the USRPs that use RFNoC. Thus, if the multi_usrp object can do something, then it is equally possible with the RFNoC API. I realize that this gets into reverse-engineering code, but it is often a good place to look for an example. Rob
