    Understanding magnetic core losses and characteristics in medium-frequency (MF) (~1-100kHz) magnetic components is an active area of research, limited by the ability to characterize and model properties, particularly losses. To build accurate models for a range of excitation waveforms, large quantities of data are required. This digest discusses the establishment of a magnetic core characterization test set-up with arbitrary excitation capability and automation for MF magnetic applications. Measurement and post-processing automation enables rapid characterization of magnetization behavior using a variety of waveforms, frequencies, and temperatures. The system is built using python to control Standard Commands for Programmable Instrumentation (SCPI) [1] enabled lab equipment and the open-source Genetic Optimization System Engineering Toolbox (GOSET) [2] for data analysis and loss-fitting. The system is equipment agnostic and transferable to any SCPI-enabled testbed. Examples of magnetic core characterization results and loss models are discussed.
