  Here we go arguing symantics again!

  The Nikonscan software calls it "analog gain", but it adjusts the exposure
time.  Since there is no "amplifier" per se, the only means of increasing
the signal is a longer integration time.  A longer integration time is also
preferable ... amplification would enhance noise, whereas time will average
the noise and reduce it.
