Member Function Documentation

◆ set_dc_corr()

void gr::funcube::fcd_impl::set_dc_corr ( double  _dci,
double  _dcq 
)
virtual

Set DC offset correction.

Parameters
_dciDC correction for I component (-1.0 to 1.0)
_dcqDC correction for Q component (-1.0 to 1.0)

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

Implements gr::funcube::fcd.

◆ set_freq()

void gr::funcube::fcd_impl::set_freq ( float  freq)
virtual

Set frequency with Hz resolution.

Parameters
freqThe frequency in Hz

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

Implements gr::funcube::fcd.

◆ set_freq_corr()

void gr::funcube::fcd_impl::set_freq_corr ( int  ppm)
virtual

Set new frequency correction.

Parameters
ppmThe 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).

Implements gr::funcube::fcd.

◆ set_iq_corr()

void gr::funcube::fcd_impl::set_iq_corr ( double  _gain,
double  _phase 
)
virtual

Set IQ phase and gain balance.

Parameters
_gainThe gain correction (-1.0 to 1.0)
_phaseThe 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.

Implements gr::funcube::fcd.

◆ set_lna_gain()

void gr::funcube::fcd_impl::set_lna_gain ( float  gain)
virtual

Set LNA gain.

Parameters
gainThe new gain in dB.

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

  1. 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.

Implements gr::funcube::fcd.

◆ set_mixer_gain()

void gr::funcube::fcd_impl::set_mixer_gain ( float  gain)
virtual

Set mixer gain.

Parameters
gainThe 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.

Implements gr::funcube::fcd.
