Abstract
The paper analyzes the main components characterizing the accuracy of phase measurement methods:
— basic error, at equal levels of the signals under study;
— amplitude-phase error at unequal levels of the signals under study.
The hardware for determining these error components is:
— a developed microcontroller two-phase phase calibrator based on DDS generators, the accuracy of setting phase shifts of which in the frequency range of up to 1 MHz is hundredths of a degree;
— a calibrated attenuator D2-31 with fixed attenuation values of 10 dB, providing a phase error at a frequency of 1 MHz of no more than 0,03º.
