The 6220 DC Bias Current Source is designed for performing magnetic saturation current (Isat) and temperature rise current (Irms) analyses on inductors, providing a single output current of 20A. For these analyses, you can pair the system with the 6632 Impedance Analyzer.
The 6632 Impedance Analyzer offers a frequency range of 100Hz to 3MHz and can handle a maximum output current of 120A using 6 units.
