Function Documentation

def grc_gnuradio.usrp.simple_usrp._set_frequency	(		u,
			which,
			subdev,
			frequency,
			verbose = False
	)			[private]

Set the carrier frequency for the given subdevice.

Parameters:

	u	the usrp source/sink
	which	specifies the DDC/DUC number
	frequency	the carrier frequency in Hz
	verbose	if true, print usrp tuning information

Definition at line 28 of file simple_usrp.py.

def grc_gnuradio.usrp.simple_usrp._setup_rx_subdev	(		u,
			subdev_spec,
			ddc,
			gain,
			frequency,
			auto_tr = None,
			rx_ant = None
	)			[private]

Setup a usrp receive subdevice by setting gain and frequency. Add the gain and frequency callbacks to the flow graph. FlexRF: Handle auto transmit/receive and set the receive antenna.

Parameters:

	u	the usrp object
	subdev_spec	the sub-device specification
	ddc	which ddc to use: 0 or 1
	gain	the gain to set
	frequency	the frequency to tune
	auto_tr	auto transmit/receive True, False, or None
	rx_ant	the receive antenna: 'TX/RX', 'RX2', or None

Returns:

the subdevice

def grc_gnuradio.usrp.simple_usrp._setup_tx_subdev	(		u,
			subdev_spec,
			gain,
			frequency,
			auto_tr = None,
			tx_enb = None
	)			[private]

Setup a usrp receive subdevice by setting gain and frequency. Add the gain and frequency callbacks to the flow graph. FlexRF: Handle auto transmit/receive and enable the transmitter.

Parameters:

	u	the usrp object
	subdev_spec	the sub-device specification
	gain	the gain to set
	frequency	the frequency to tune
	auto_tr	auto transmit/receive True, False, or None
	tx_enb	the transmit enable: True, False, or None

Returns:

the subdevice
