The DC Bias Source Testing System combines the impedance analyzer 6632S with a DC bias source. This system is capable of analyzing the saturation characteristics of inductors, coils, ferrites, and magnetic cores. 6632S supports Equivalent Circuit Analysis with seven different models to assist customers in analyzing the impact of parasitic components on impedance/frequency. The system supports magnetic saturation current and temperature rise current scanning analysis, providing research and development engineers with fast and accurate current curve variations.
