Impossible to say. It depends on what A/D converter you have, how it's
controlled and read out, and lots of other things --- none of which have
much to do with gnuplot.

Generally speaking, creating datafiles for gnuplot should be about two
orders of magnitude easier than creating Excel files from scratch.  See 
"help splot data" and "help glossary".
