This sort of thing makes perfect sense for a spreadsheet.

Our RF engineer uses them for working out receiver gain distribution and other 

We use the Tcl/Tk program for doing stuff like calculating output power of a 
transmitter as you look at the scope on its sniff port.. much faster than 
loading a spreadsheet :)

Languages like Tcl are *very* easy to program even for novice coders (like our 
RF engineer :) and are usually very portable as well.
