Abstract

The problem of constructing precision apparatus for generating a sine-wave signal based on the direct digital synthesis method is considered. A block diagram and the basic technical characteristics are presented, and the individual units of the G3-135, G3-136, and G3-137 generators, the harmonic distortion coefficients of which are less than 0.001%, are described. The results of tests of the generators at the achieved value of the harmonic distortion coefficient are presented.
