Member Function Documentation

double microtune_4937::get_output_freq

(

)

[virtual]

Returns:

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

Implements microtune_xxxx.

bool microtune_4937::pll_locked_p

(

)

[virtual]

Returns:

true iff PLL is locked

Implements microtune_xxxx.

bool microtune_4937::set_RF_freq	(	double	freq,
		double *	actual_freq
	)		[virtual]

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.

Implements microtune_xxxx.
