TWO-CHANNEL ADC SYSTEM FOR HYSTERESISGRAPH
A. Platil, P. Ripka, J. Roztoèil
Abstract:
System for measurement of dynamic hysteresis loops is based on a pair of measuring ADC boards. Influence of different phase shift in both channels causes false phase information in the digitised signals. The character of the phase shift was identified as transport delay and its frequency dependence was measured. Software correction was implemented and tested. Study of the effective number of bits of resolution is also presented.
