The experimental results of investigations on capillary wave turbulence on the surface of water, using low-frequency pumping in the range from 20 to 200 Hz, are presented. The correlation function of deviations of the surface from the equilibrium state in the frequency range of 300 Hz–8 kHz can be described by a power function, scaling with an exponent close to . It is observed that the high-frequency boundary of the inertial interval, in which scaling is realized, is shifted towards higher frequencies with increasing amplitude of pumping.
