thank you Eric for the useful information that cleared many doubts. My specific doubt is: as following statement Determine the appropriate Rx mux value as a function of the subdevice choosen and the characteristics of the respective daughterboard int usrp_standard_rx::determine_rx_mux_value ( const usrp_subdev_spec &ss ) in http://gnuradio.org/doc/doxygen/classusrp__standard__rx.html what is the rx_mux_value for daughter boards flex900 and flex2400? >From whare that is loaded by default for any daughter board?
