def db_dbs_rx::db_dbs_rx::__del__ (   self  ) 

def db_dbs_rx::db_dbs_rx::__init__ (   self,
  usrp,
  which 
)

Control DBS receiver based USRP daughterboard.

Parameters:
usrp,: instance of usrp.source_c
which,: which side: 0 or 1 corresponding to RX_A or RX_B respectively which: int

Reimplemented from db_base::db_base.

def db_dbs_rx::db_dbs_rx::freq_range (   self  ) 

Return range of frequencies in Hz that can be tuned by this d'board.

Returns:
(min_freq, max_freq, step_size) tuple

Reimplemented from db_base::db_base.

def db_dbs_rx::db_dbs_rx::gain_range (   self  ) 

Return range of gain that can be set by this d'board.

Returns:
(min_gain, max_gain, step_size) Where gains are expressed in decibels (your mileage may vary)

Reimplemented from db_base::db_base.

def db_dbs_rx::db_dbs_rx::is_quadrature (   self  ) 

Return True if this board requires both I & Q analog channels.

This bit of info is useful when setting up the USRP Rx mux register.

Reimplemented from db_base::db_base.

def db_dbs_rx::db_dbs_rx::set_bw (   self,
  bw 
)

def db_dbs_rx::db_dbs_rx::set_freq (   self,
  freq 
)

Set the frequency.

Parameters:
freq,: target frequency in Hz freq: float
Returns:
(ok, actual_baseband_freq) where: ok is True or False and indicates success or failure, actual_baseband_freq is the RF frequency that corresponds to DC in the IF.

Reimplemented from db_base::db_base.

def db_dbs_rx::db_dbs_rx::set_gain (   self,
  gain 
)

Set the gain.

Parameters:
gain,: gain in decibels
Returns:
True/False

Reimplemented from db_base::db_base.
