Hello Jose, The B210's two channels use a common local oscillator so cannot tune to two separate analog frequencies. http://files.ettus.com/manual/page_usrp_b200.html#b200_fe
However if your two center frequencies are relatively close together, such that the minimum and maximum frequencies of your modulated waveforms are less than 30.72 MHz apart the FPGA's frequency shifters can be used to digitally tune each channel's center frequency. The basics of this are described on this page in the manual. We'd be happy to describe the process in more detail if it fits your application. http://files.ettus.com/manual/page_general.html#general_tuning_process Regards, Derek On Thu, Mar 15, 2018 at 1:22 PM, Jose Benito Diéguez Teixeira via USRP-users <usrp-users@lists.ettus.com> wrote: > Hello usrp users, > > We are using a B210 SDR device for our application.
