Abstract :
The paper characterizes selected properties of a dual-channel digitizer designed for a low value resistor calibration system working in the frequency range from 40 Hz to 10 kHz. There are presented the experimentally determined frequency characteristics of magnitude and phase of the complex voltage ratio, as well as the research results of the digitizer linearity and the phase measurement accuracy.
