  We examine how the abilities of an SDC-like detector to discover and identify
the origin of a new neutral gauge boson are affected by $Z_1-Z_2 $ mixing and
by variations in detector parameters such as lepton pair mass resolution,
particle identification efficiency, and rapidity coverage. Also examined is the
sensitivity of these results to variations in structure function uncertainties
and uncertainties in the machine integrated luminosity. Such considerations are
of importance when dealing with the issues of detector descoping and design.
