Member Function Documentation

◆ args_to_io_signature()

gr::io_signature::sptr gr::limesdr::sink_impl::args_to_io_signature ( int channel_number )

inline

◆ calibrate()

void gr::limesdr::sink_impl::calibrate	(	double	bandw,
		int	channel = 0 )

virtual

Perform device calibration.

Parameters

bandw	Set calibration bandwidth in Hz.
channel	Channel selection: A(LMS_CH_0),B(LMS_CH_1).

Implements gr::limesdr::sink.

◆ init_stream()

void gr::limesdr::sink_impl::init_stream	(	int	device_number,
		int	channel )

◆ read_gpio()

uint8_t gr::limesdr::sink_impl::read_gpio ( )

virtual

Read GPIO inputs

Read GPIO inputs by calling LMS_GPIORead()

Returns: input level bitmap (eight bits, one for each pin)

Implements gr::limesdr::sink.

◆ release_stream()

void gr::limesdr::sink_impl::release_stream	(	int	device_number,
		lms_stream_t *	stream )

◆ set_antenna()

void gr::limesdr::sink_impl::set_antenna	(	int	antenna,
		int	channel = 0 )

virtual

Set which antenna is used

Note: setting antenna to BAND1 or BAND2 will enable PA path and because of that Lime boards will transmit CW signal, even when stream is stopped.

Parameters

antenna	Antenna to set: None(0), BAND1(1), BAND(2), NONE(3), AUTO(255)
channel	Channel selection: A(LMS_CH_0),B(LMS_CH_1).

Implements gr::limesdr::sink.

◆ set_bandwidth()

double gr::limesdr::sink_impl::set_bandwidth	(	double	analog_bandw,
		int	channel = 0 )

virtual

Set analog filters.

Parameters

analog_bandw	Channel filter bandwidth in Hz.
channel	Channel selection: A(LMS_CH_0),B(LMS_CH_1).

Returns: actual filter bandwidth in Hz

Implements gr::limesdr::sink.

◆ set_buffer_size()

void gr::limesdr::sink_impl::set_buffer_size ( uint32_t size )

virtual

Set stream buffer size

Parameters

size	FIFO buffer size in samples

Implements gr::limesdr::sink.

◆ set_center_freq()

double gr::limesdr::sink_impl::set_center_freq	(	double	freq,
		size_t	chan = 0 )

virtual

Set center frequency

Parameters

freq	Frequency to set in Hz
chan	Channel (not used)

Returns: actual center frequency

Implements gr::limesdr::sink.

◆ set_digital_filter()

void gr::limesdr::sink_impl::set_digital_filter	(	double	digital_bandw,
		int	channel = 0 )

virtual

Set digital filters (GFIR).

Parameters

digital_bandw	Channel filter bandwidth in Hz.
channel	Channel selection: A(LMS_CH_0),B(LMS_CH_1).

Implements gr::limesdr::sink.

◆ set_gain()

unsigned gr::limesdr::sink_impl::set_gain	(	unsigned	gain_dB,
		int	channel = 0 )

virtual

Set the combined gain value in dB

Note: actual gain depends on LO frequency and analog LPF configuration and resulting output signal level may be different when those values are changed

Parameters

gain_dB	Desired gain: [0,73] dB
channel	Channel selection: A(LMS_CH_0),B(LMS_CH_1).

Returns: actual gain in dB

Implements gr::limesdr::sink.

◆ set_tcxo_dac()

void gr::limesdr::sink_impl::set_tcxo_dac ( uint16_t dacVal = 125 )

virtual
