DC Bias Current Source Testing System, paired with the 6632 Impedance Analyzer, can analyze the saturation characteristics of inductors, coils, ferrites, and cores. It also provides relative permeability (μr) testing, analyzing key characteristics of magnetic materials. The system supports magnetic saturation current and temperature rise current sweep analysis, offering quick and accurate current curve changes for R&D engineers. It can be integrated into production lines with the option of meter mode or multi-step mode. Measurement results are displayed numerically, and the system supports PC connection software for data storage or report analysis.
