Member Enumeration Documentation

sampling_t

enum uhd::usrp::fe_connection_t::sampling_t

Sampling mode. Represents the sampling architecture for the front-end

Enumerator
QUADRATURE	Complex sampling (Complex input, Complex output).
HETERODYNE	Heterodyne sampling (Real input, Complex output). Only one of the I and Q inputs is used.
REAL	Real sampling (Real input, Real output). Only one of the I and Q inputs is used.

Constructor & Destructor Documentation

fe_connection_t() [1/2]

uhd::usrp::fe_connection_t::fe_connection_t	(	sampling_t	sampling_mode,
		bool	iq_swapped,
		bool	i_inverted,
		bool	q_inverted,
		double	if_freq = 0.0
	)

Create a frontend connection class from individual settings.

Parameters

sampling_mode	can be { QUADRATURE, HETERODYNE, REAL }
iq_swapped	indicates if the IQ channels are swapped (after inverion and heterodyne correction)
i_inverted	indicates if the I channel is inverted (negated)
q_inverted	indicates if the Q channel is inverted (negated)
if_freq	the baseband sampling frequency.

fe_connection_t() [2/2]

uhd::usrp::fe_connection_t::fe_connection_t	(	const std::string &	conn_str,
		double	if_freq = 0.0
	)

Create a frontend connection class from a connection string The connection string can be:

• in {I, Q}: Real mode sampling with no inversion.
• in {Ib, Qb}: Real mode sampling with inversion.
• in {IQ, QI}: Quadrature sampling with no inversion.
• in {IbQb, QbIb}: Quadrature sampling with inversion.
• in {II, QQ}: Heterodyne sampling with no inversion.
• in {IbIb, QbQb}: Heterodyne sampling with inversion.

Parameters

conn_str	the connection string.
if_freq	the baseband sampling frequency.
