A good knowledge of the beam optics is important for many aspects of accelerator operation. Furthermore, when large deviations are observed with respect to the nominal machine model, a correction of the optics may be required. A simple method to verify the beam optics consists in measuring the orbit response to kicks applied with steering magnets. Besides providing a fast qualitative check of the optics, such measurements can be used to correct the machine model and evaluate beam position monitor and steering magnet calibrations. In 2001 this method was evaluated experimentally in the SPS. Results and fits of the SPS machine model to the data will be presented. Potential applications of this method to the long SPS-LHC transfer lines will also be discussed.
