Widely known methods of measuring instrument errors on a constant signal place high demands on precision formation test signals. Methods for measuring the ac signal free from high demands on the accuracy of the test signal. There are several methods for measuring the random component of the instrumental error of ADC on an alternating signal. This article discusses a method for measuring the distortion of the density distribution of samples. Is rectilinear scanning test signal within the scope of the random instrumental errors. Uniform sampling is performed with a given number of samples at a nominal level of quantization. The cases of small measurement noise when the scope of random instrumental error does not exceed the level of quantization, and random noise. The analysis of errors of measurement results. Formulated a program of experiments and the estimation algorithm of the measured value.
