SY-8232 B-H Analyzer
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 circuitand 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.
*Ultrawide measurement frequency bandwidth
The frequency range for measurement is exceptionally wide, from 10 Hz (optionally 1 Hz) to 10 MHz.
* Desktop size, all-in-one construction
A compact design incorporating an oscillation circuit, power amplifier circuit, high-speed digitizer, operation control circuit and printer.
Magnetic head material can be directly measured by the built-in power amplifier (25 VA) for excitation. (An optional external power
amplifier can also be used.)
*Continuous measurement function and an extensive selection of other
Continuous measurement with up to 12 steps, and various measurements including a B-H curve, core loss curve, μ-
characteristics and L-characteristics, are available.
*High-speed, high-precision measurement
High-speed measurement in approx. 3 seconds can be performed. In addition, an FFT arithmetic circuit permits automatic compensation
and calibration of frequency characteristics, enabling high-precision measurements.
*Printer provided as standard (built-in)
Measurement results can be printed out immediately. Convenient for data sorting.
*GP-IB interface provided as standard
An automated measurement system in combination with a PC can be configured.
*Easy-to-view 9-inch color CRT display
*Easy operation with pop-up menu system
Pop-up menus are displayed on the CRT to facilitate operation. Results are displayed as graphs or lists.
*Enhanced measurement efficiency with a wide range of options
Options include an external power amplifier and sample connection pod for various use.
R&D of magnetic heads, power ferrite, ultrathin amorphous materials, etc.
Example of Combination
* Core loss measurement of transformers for high-frequency power supplies
By combining the SY-8232 B-H analyzer with the GB-12145 power amplifier (optional), core loss up to 3 MHz can be measured.
* GB-12145 will be alternated with IE-1125 on and after the 2nd half of 2000.
