Description
| 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. |
