- Abstract:
- Today uncertainties of a phase difference of two sinusoidal signals is commonly about 10 μrad for non coherent measurements and signal amplitudes up to several volts. Increasing voltage range of a phase meter requires special considerations. The construction of a special voltage divider intended for precise phase difference measurement is presented in this paper. The uncertainty contribution of the voltage divider was determined by repeated measurement and an Allan variance calculation. The result showed out the voltage range of the phase meter increased substantially with very small addition to the total uncertainty of the phase difference.
