Member Function Documentation

double microtune_4937::get_output_freq (   )

Returns: the output frequency (IF center freq) of the tuner in Hz.

virtual int microtune_4937::i2c_read (  int  addr, unsigned char *  buf, int  max_bytes )  [private, pure virtual]

Returns: number of bytes read or -1 if error Implemented in microtune_eval_board.

virtual bool microtune_4937::i2c_write (  int  addr, const unsigned char *  buf, int  nbytes )  [private, pure virtual]

Returns: true iff successful Implemented in microtune_eval_board.

bool microtune_4937::pll_locked_p (   )

Returns: true iff PLL is locked

double microtune_4937::set_RF_freq (  double  freq  )

bool microtune_4937::set_RF_freq (  double  freq, double *  actual_freq )

select RF frequency to be tuned to output frequency. freq is the requested frequency in Hz, actual_freq is set to the actual frequency tuned. It takes about 100 ms for the PLL to settle. Returns: true iff sucessful.
