  This study investigates the potential of the TESLA Linear Collider for
measuring resonance parameters of Higgs bosons beyond the mass range studied so
far.
  The analysis is based on the reconstruction of events from the Higgsstrahlung
process e+e- -> HZ. It is shown that the total width, the mass and the event
rate for Higgs production can be measured from the mass spectrum in a model
independent fit. Also, the branching ratios to W- and Z-bosons can be measured,
assuming these are the only relevant Higgs decay modes.
  The simulation includes realistic detector effects and all relevant Standard
Model background processes. Results are given for mH=200-320 GeV assuming 500
fb^-1 integrated luminosity at collision energies of 500 GeV.
