本仪器通过荧光屏显示磁带、磁浆或磁粉的磁滞回线和导数曲线,从而确定它们的磁性参数。系统的灵敏度约0.1M_x/cm,信噪比大于15。对于参考磁带Scotch777的测量结果,其偏差在5%之内本仪器的特点是采用先积分后放大的方案,减小了系统的频率失真;并且采用线性集成电路和有效地抵消磁场磁通,因此大大地提高了系统的信噪比和稳定性。
The instrument displays the magnetic hysteresis loop and derivative curve of magnetic tape, magnetic slurry or magnetic powder through the fluorescent screen to determine their magnetic parameters. System sensitivity of about 0.1M_x / cm, signal to noise ratio greater than 15. For reference tape Scotch777 measurement results, the deviation is within 5% The instrument features a first integrated after amplification scheme to reduce the system frequency distortion; and the use of linear integrated circuits and effectively offset the magnetic flux field, therefore Greatly improve the system’s signal to noise ratio and stability.
