Given an instance of the daughterboard in question, you can ask it:
subdev.freq_range()
or
subdev.gain_range()
for the valid gain ranges
>From the abstract daughterboard base class db_base.py:
def freq_range(self):
"""
Return range of frequencies in Hz that can be tuned by this d'board.
@returns (min_freq, max_freq, step_size)
@rtype tuple
"""
raise NotImplementedError
def 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)
"""
raise NotImplementedError
