Dear All, I am trying to migrate from home-made daughterboard code to the code by Trondeau. I am using the version 9305. I use db_flexrf_1800_tx_mimo_b. After changing "d_common->R_DIV(1)" to "d_common->R_DIV(16)" the signal is showing up on my spectrum analyzer at the correct frequency. However, the amplitude is about 25dB weaker than when using the home-made daughterboard code. I am using the daughterboard code as given by the code fragment below. Does anyone have an idea what could be wrong ?
BR/ Per usrp_standard_tx* tx = usrp_standard_tx::make(0,64,2,47768); std::vector<db_base_sptr> db_rx0,db_rx1,db_tx0,db_tx1; db_tx0=tx->db(0); db_tx1=tx->db(1); db_tx0[0]->set_lo_offset(tx_lo_offset); tr=db_tx0[0]->tune(0,carrier_frequency); db_tx0[0]->set_enable(true); db_tx0[0]->set_gain(db_tx0[0]->gain_max()); _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
