- Abstract:
- Two commercial two-phase digital AC voltage sources, WW2572A from Tabor Electronics and SYS-2722 from Audio Precision, were tested for their potential use in impedance comparator bridges. The mutual relative stability of magnitudes and phase shifts of their output voltages were evaluated. Results of relative amplitude and phase shift stability measurements prove that it is possible to obtain uncertainty of impedance comparison at 10-5 level?using the WW2572A or SYS-2722 as the two-phase AC voltage source in the balanced comparator bridge.
