SY-8232B-H AnalyzerThe SY-8232 high-frequency B-H analyzer is theflagship of IWATSU’s line of B-H analyzers. It has ahigh-frequency B-H curve tracing capability over anultrawide-range measurement frequency from 10Hz (optionally 1 Hz) to 10 MHz.The SY-8232’s compact design makes it ideal fordesktop use. It incorporates features required formeasuring high-frequency magnetic characteristics,including an oscillation circuit, power amplifiercircuit, high-speed digitizer, operation control circuitand a printer.The built-in 25 VA power amplifier allows directmeasurement of small specimens such as magneticheads, while use of an external power amplifierenables measurement of large amplitudecharacteristics and saturation characteristics ofpower ferrite or ultrathin amorphous materials. Thelower limit frequency is as low as 10 Hz (optionally1 Hz), permitting the measurement of near DCmagnetic characteristics of soft magnetic materials.As the analyzer allows both near DC and AC, themeasurements of coercive force (Hc) related tomagnetic wall production, migration and extinctioncan be more effective and research and testing inmaterials development can be performed morequickly.*Ultrawide measurement frequencybandwidthThe frequency range for measurement is exceptionally wide,from 10 Hz (optionally 1 Hz) to 10 MHz.*Desktop size, all-in-one constructionA compact design incorporating an oscillation circuit, power amplifiercircuit, high-speed digitizer, operation control circuit and printer.Magnetic head material can be directly measured by the built-inpower amplifier (25 VA) for excitation. (An optional external poweramplifier can also be used.)*measuring functionsContinuous measurement function andan extensive selection of otherContinuous measurement with up to 12 steps, and variousmeasurements including a B-H curve, core loss curve, μ-characteristics and L-characteristics, are available.*High-speed, high-precisionmeasurementHigh-speed measurement in approx. 3 seconds can be performed. Inaddition, an FFT arithmetic circuit permits automatic compensationand calibration of frequency characteristics, enabling high-precisionmeasurements.*Printer provided as standard (built-in)Measurement results can be printed out immediately. Convenient fordata sorting.*GP-IB interface provided as standardAn automated measurement system in combination with a PC can beconfigured.*Easy-to-view 9-inch color CRT display*Easy operation with pop-up menusystemPop-up menus are displayed on the CRT to facilitate operation.Results are displayed as graphs or lists.*Enhanced measurement efficiency witha wide range of optionsOptions include an external power amplifier and sample connectionpod for various use.Major ApplicationsR&D of magnetic heads, power ferrite, ultrathin amorphous materials, etc.Example of Combination*Core loss measurement of transformersfor high-frequency power suppliesBy combining the SY-8232 B-H analyzer with the GB-12145 power amplifier (optional), core loss up to 3 MHzcan be measured.* GB-12145 will be alternated with IE-1125 on and after the 2nd halfof 2000.
