SOFTWARE FOR AMORPHOUS MATERIALS SINGLE STRIP TESTERS

Ivan Zemánek

   PC controlled single strip tester (SST) for amorphous magnetic materials laboratory testing based on MMF Czech compensation method was developed. The SST can be used for the measurement of dynamic hysteresis loops of amorphous magnetic materials at arbitrary waveform magnetization up to 20 kHz and for the determination of all important material parameters by the digital processing of digitized measured signals H(t) and B(t). The SST functions are controlled by special user friendly dialogue mode control software developed in Microsoft Visual Studio C++ 6.0 and National Instruments Measurement Studio 6.0 as Windows XP application executable on standard PC completed by three special PC plug-in boards serving as the arbitrary exciting signalgenerator and analogue-digital measuring boards, respectively.
