Abstract
A practical estimate of the accuracy of calculations of a software-hardware system consisting of an audio-frequency generator and a combined spectrum analyzer is presented. It is shown, using the example of a number of model measurements, that the frequency, amplitude, and phase errors of the calculations are very close to the theoretical limits.
