GR_UHD_API boost::shared_ptr<uhd_usrp_source> uhd_make_usrp_source	(	const uhd::device_addr_t &	device_addr,
		const uhd::stream_args_t &	stream_args
	)

Make a new USRP source block.

The USRP source block receives samples and writes to a stream. The source block also provides API calls for receiver settings.

RX Stream tagging:

The following tag keys will be produced by the work function:

• pmt::pmt_string_to_symbol("rx_time")

The timstamp tag value is a pmt tuple of the following: (uint64 seconds, and double fractional seconds). A timestamp tag is produced at start() and after overflows.

See the UHD manual for more detailed documentation: http://code.ettus.com/redmine/ettus/projects/uhd/wiki

Parameters:

device_addr	the address to identify the hardware
stream_args	the IO format and channel specification

Returns:

a new USRP source block object
