초록
Analog-digital converter boards for use in personal computers have recently being improved markedly, many kinds of high speed(1 MHz - 10 MHz sampling rale) and over 12-bit vertical resolution A/D boards released. It can be applicable to high frequency magnetic measurements. In measurement of magnetic properties of high frequency, digitizing oscilloscope or trasient recorder are being used. but, those price are often expensive, we constructed PC controlled A-C B-H loop tracer that can measure Bs, Br, He, permeability and may be applied about 100 Hz - 20 kHz range. it use IBM PC compatible 1 M Sample/s, 12 bit A/D converter board with SSH(Simultaneous Sample and Hold).
