Maximo,
Did you find the find the windows software? Most of the values you're
seeking could be derived using Master Sweep Tools.

Line sweep tools is one. VMA master is aother. Both are completely
free.LST records datam MST allows far more than basic manipulation
MIne is odd. It requires a rs-232 dummy mode, then an rs cable.
