Abstract Inductors are critical components in electronic circuits, and the magnetic core within them directly determines their performance stability and service life. Traditional inductance testing methods often fail to accurately reflect the actual working state of the core due to the lack of a DC bias current environment. This paper takes the LISUN LS1373 LCR Meter with DC Bias Current Source as the core testing tool, systematically explores how to use its built-in DC bias current source to analyze the characteristics of inductor cores, and verifies its application value in inductor quality inspection and product characteristic analysis through experimental data. The results show that the LS1373 DC Bias Current Source can simulate the actual working current of the inductor, accurately measure core parameters such as inductance (L) and quality factor (Q) under different bias conditions, and provide reliable data support for judging the core quality and optimizing the inductor design. ...
