摘要
提出了一种理论计算的新方法,它可根据数字记录仪的指数波响应计算冲击电压的数字测量误差。利用这种方法,计算了冲击电压峰值和波前时间的数字测量误差,并分析了误差的影响因素和变动范围。最后,测量误差的计算结果与实测误差作对比检验,证实了这种理论计算方法在实际应用中是有效的。
This paper presents a new theoretical calculation method which can be used to calculate errors in digital measurement of impulses based upon the exponential wave response of the digital recorder. Errors in digital measurement of the peak value and front time of impulses are calculated by this method, with influence factors and variance ranges analysed. Finally, the calculated results of measurement errors are checked by comparison with the measured errors. The effectiveness of this theoretical calculation method for practical application is thus proved.
