The SY-8232 high-frequency B-H analyzer is the flagship of IWATSU’s line of B-H analyzers. It has a high-frequency B-H curve tracing capability over an ultrawide-range measurement frequency from 10 Hz (optionally 1 Hz) to 10 MHz. The SY-8232’s compact design makes it ideal for desktop use. It incorporates features required for measuring high-frequency magnetic characteristics, including an oscillation circuit, power amplifier circuit, high-speed digitizer, operation control circuit and a printer. The built-in 25 VA power amplifier allows direct measurement of small specimens such as magnetic heads, while use of an external power amplifier enables measurement of large amplitude characteristics and saturation characteristics of power ferrite or ultrathin amorphous materials. The lower limit frequency is as low as 10 Hz (optionally 1 Hz), permitting the measurement of near DC magnetic characteristics of soft magnetic materials. As the analyzer allows both near DC and AC, the measurements of coercive force (Hc) related to magnetic wall production, migration and extinction can be more effective and research and testing in materials development can be performed more quickly. 二、产品详细参数Specifications
