Detailed Description

Funcube Dongle source block.

This class provides a Funcube Dongle soure block by wrapping the USB audio interface and the USB HID control interface of the Funcube Dongle into one convenient source block.

The Funcube Dongle needs to have firmware 18f or later for the control interface to work properly. As of early 2011, FCDs still come with firmware 18b. You can use qthid 2.2 (not 3) to upgrade the firmware: http://qthid.sf.net

Member Typedef Documentation

typedef boost::shared_ptr<source_c> gr::fcd::source_c::sptr

Member Function Documentation

static sptr gr::fcd::source_c::make ( const std::string device_name = "" )

static

Return a shared_ptr to a new instance of fcd_source_c.

This is effectively the public constructor. To avoid accidental use of raw pointers, fcd_source_c's constructor is private. fcd_make_source_c is the public interface for creating new instances.

virtual void gr::fcd::source_c::set_dc_corr	(	double	_dci,
		double	_dcq
	)

pure virtual

Set DC offset correction.

Parameters

_dci	DC correction for I component (-1.0 to 1.0)
_dcq	DC correction for Q component (-1.0 to 1.0)

Set DC offset correction in the device. Default is 0.0.

virtual void gr::fcd::source_c::set_freq ( int freq )

pure virtual

Set frequency with Hz resolution.

Parameters

freq	The frequency in Hz

Set the frequency of the Funcube Dongle with 1 Hz resolution applying the frequency correction set by set_freq_corr().

See Also: set_freq_khz()

virtual void gr::fcd::source_c::set_freq ( float freq )

pure virtual

Set frequency with Hz resolution.

Parameters

freq	The frequency in Hz

This is a convenience function that uses float parameter in order to allow using engineering notation in GRC.

See Also: set_freq_khz()

virtual void gr::fcd::source_c::set_freq_corr ( int ppm )

pure virtual

Set new frequency correction.

Parameters

ppm	The new frequency correction in parts per million

Version 1.1 FCDs (S/N 810 or later) need a correction of -12 ppm. Earlier FCDs need roughly -120 ppm (default for gr-fcd).

Ref: http://www.funcubedongle.com/?p=617

virtual void gr::fcd::source_c::set_freq_khz ( int freq )

pure virtual

Set frequency with kHz resolution.

Parameters

freq	The frequency in kHz

Sets the frequency of the Funcube Dongle with 1 kHz resolution applying the frequency correction set by set_freq_corr().

See Also: set_freq()

virtual void gr::fcd::source_c::set_iq_corr	(	double	_gain,
		double	_phase
	)

pure virtual

Set IQ phase and gain balance.

Parameters

_gain	The gain correction (-1.0 to 1.0)
_phase	The phase correction (-1.0 to 1.0)

Set IQ phase and gain balance in the device. The default values are 0.0 for phase and 1.0 for gain.

virtual void gr::fcd::source_c::set_lna_gain ( float gain )

pure virtual

Set LNA gain.

Parameters

gain	The new gain in dB.

Set the LNA gain in the FCD. Valid range is -5 to

Although the LNA gain in the FCD takes enumerated values corresponding to 2.5 dB steps, you can can call this method with any float value and it will be rounded to the nearest valid value.

By default the LNA gain is set to 20 dB and this is a good value for most cases. In noisy areas you may try to reduce the gain.

virtual void gr::fcd::source_c::set_mixer_gain ( float gain )

pure virtual

Set mixer gain.

Parameters

gain	The new gain in dB.

Set the mixer gain in the FCD. Valid values are +4 and +12 dB.

By default the mixer gain is set to +12 dB and this is a good value for most cases. In noisy areas you may try to reduce the gain.
