  We explore an alternative to the usual procedure of scanning for determining
the properties of a narrow $s$-channel resonance. By varying the beam energy
resolution while sitting on the resonance peak, the width and branching ratios
of the resonance can be determined. The statistical accuracy achieved is
superior to that of the usual scan procedure in the case of a light SM-like
Higgs boson with $\mh>130\gev$ or for the lightest pseudogoldstone boson of a
strong electroweak breaking model if $\mpzero>150\gev$.
