We investigate the evolution of timing and spectral properties of XTE 1859+226 during its 1999 outburst. We consider the formation of energy spectrum in terms of Comptonization model and the formation of Fourier power density spectrum in terms of disk perturbation diffusion propagation model. We found strong correlations between QPO frequency and energy spectral index similar to observed in other BH binaries. We establish the saturation effect claimed to be black hole signature. We also estimate a mass of central black hole using a method of QPO-index correlation scaling.
