示波器垂直偏转系数示值误差测量结果的不确定度评定

Assessment of Uncertainty in the Measurement Result of Indication Error of Oscillograph Vertical Deflection Coefficient

对示波器垂直偏转系数示值误差测量结果的不确定度进行了评定。测量不确定主要来源于测量的重复性、示波器校准仪标准方波不确定度和示波器校准仪垂直分辩力引入的标准不确定度。

Uncertainty in the measurement result of indication error of oscillograph vertical deflection coefficient is assessed. Measurement uncertainty originates from repeatability of measurement, uncertainty in the square wave of oscillograph calibrator and uncertainty in the standard introduced by the vertical resolution of oscillograph calibrator.
