Abstract. The real values of dynamical characteristics in Nuclotron have been measured by means of both sinusoidal and kick excitations of the beam. For measurement of betatron tunes the method based on the Beam Transfer Function has been used. Beam-based modeling by means of Orbit Response Matrix allowed us to calculate the amplitude beta function and the betatron phase advance with big accuracy. Applying this method, one can also calibrate the Beam Position Monitors, and reveal the bad-working units.
