I was wondering about that myself.  NikonScan calls it "analog gain," but
since exposure time seems to be the usual way of doing things, I was
wondering why or if the Nikon scanners did it the same way.

I prefer extending the exposure time to trying to boost the gain, although I
suppose longer exposure time increases noise, too (but hopefully to a lesser
extent).
