Sažetak
Sampling of a sine waveform with high-resolution integrating DMM with the input parameters, such as aperture, sampling and measurement time, number of bursts, the number of harmonics, expected RMS and measured frequency of a signal can be accurate to 5 ppm. The precision of a measured frequency can highly influence on sampling parameters. The amplitude of expected RMS behaves as sinc function due change of an aperture time. Still the error exists. The alternative method for correction of a root-mean-square value of a measured sine signal due impact of aperture time is presented.
