The Flex400 driver (db_flex.py) has the following code:
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)
Flex Tx boards require that the PGA be maxed out to properly
bias their circuitry.
"""
g = self._u.pga_max()
return (g, g, 1.0)
Am I understanding correctly that there is no way to adjust gain on
the TX path? If I modified the code to allow programming of lower
values in the PGA, what would the effect be? I mean, would that be a
bad thing?
Thanks!
