I looked at the source and found the following. /*! * \brief High-level "tune" method. Works for the single channel case. * * This method adjusts both the daughterboard LO and the DDC so that * target_freq ends up at DC in the complex baseband samples. * * \param chan which DDC channel we're controlling (almost always 0). * \param db the daughterboard we're controlling. * \param target_freq the RF frequency we want at DC in the complex baseband. * \param[out] result details how the hardware was configured. * * \returns true iff everything was successful. */ Thomas _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
