用具有行波型偏转系统的阴极射线管制作的示波记录器广泛用于快速单次物理过程的特性测量。示波记录器中,在荧光屏工作区的相应中心轴线上将时间 t 和电压 u 分别正交变换为若干段直线 x=K_p~(-1)t;Y=K_0~(-1)u(式中,K_p 和 K_o 是扫描系数与偏转系数。荧光屏上应保证以波形图(或光波形图)Y=f(x)的形式无畸变地再现过程 u=f(t)。当 K_p 与
Oscillographic recorders made with cathode ray tubes with traveling-wave deflection systems are widely used to characterize fast single physical processes. In the oscillographic recorder, the time t and the voltage u are respectively orthogonally transformed into several straight lines x = K_p ~ (-1) t on the corresponding central axis of the working area of the fluorescent screen; Y = K_0 ~ (-1) u , K_p and K_o are the scanning coefficient and the deflection coefficient, and the screen should ensure that the process u = f (t) is reproduced without distortion in the form of a waveform (or light waveform) Y = f (x)
