At higher excitation frequencies, rising impedance can make it more difficult to supply sufficient excitation energy. A power amplifier addresses this by increasing the SY-8264 output signal. The excitation signal is routed from the SY-8264 to the amplifier, amplified, and then returned to the measurement pod to drive the DUT.

Users can input key sample parameters (e.g., effective magnetic length, cross-sectional area, number of turns) and test conditions (e.g., frequency, peak field strength Hm, flux density Bm, voltage V2m, current I1m). The analyzer then automatically generates accurate B-H hysteresis curves and calculates the corresponding magnetic properties.
The SY-810 Remote Control Software supports seamless operation of various optional test systems.
As frequencies increase in applications like switching power supplies and DC-DC converters, core losses—primarily due to hysteresis and eddy currents—become critical. These losses lead to temperature rise and hinder miniaturization. Measuring and minimizing core loss in soft magnetic materials is key to developing more efficient, compact designs.
Understanding magnetic saturation is essential when designing with soft magnetic materials. The B-H Analyzer delivers accurate B-H curves across a wide frequency range—including into the MHz domain—making it the only tool capable of capturing saturation behavior under real-world conditions.
Materials such as silicon steel, soft iron, permalloy, and stainless steel vary significantly in magnetic performance based on manufacturing and heat treatment. The B-H Analyzer provides a reliable method for characterizing permeability and inductance, facilitating data-driven material improvements—even in common ferrite cores.
Sample parameters (Effective magnetic length, Effective cross section, number of turns of windings, etc.) and test conditions (Frequency, Maximum field strength: Hm, Maximum flux density: Bm, Maximum induced voltage: V2m, Maximum exciting current: I1m) inputs enable obtaining BH hysteresis curve and magnetic properties in value automatically.
Temperature scanner system, Single Sheet test system and DC biasing system are able to control with the SY-810 Remote control software.
