attenuator.c: DAT-31A-S+ has 6th unused bit
...
So In reality DAT-31A-S+ seems to have steps of 0.5dB, but the LSB
is "defined" to be alwasy 0. This means we have to multiply the
dB value by 2 (shift one left) to make sure the LSB in 0.5dB steps
remains 0, and to make sure we actually step n steps of 1dB
