The probability density fluctuations of the harmonic signal at the change of its frequency and time between elements of samples have been measured in a model experiment. The possibility of the use of the criterion of the first output from the field of comparison for the approximation of the distributions of probability density fluctuations of harmonic signal is studied. Its suitability for measurements in dependent and independent samples is shown.
