摘　　要：提出了一种数字电视码流发生器的校准方法,并分析了其测量不确定度e主要的校准项目为解码后的串行数字信号的质量参数,包括眼图幅度、上升时间、下降时间、直流偏置、定时抖动、校准抖动和比特率等@该校准方法旨在解决数字电视码流发生器在校准过程中存在的问题,从而更全面地对其技术特性进行校准s该校准方法具有可操作性和实施的经济性,对于保障数字视频产品的质量具有重要的意义。A calibration method for digital TV code stream generator is proposed and its measurement uncertainty is analyzed. The main calibration items are the quality parameters of decoded serial digital signals, including eye diagram amplitude, rise time, descent time,DC bias,timing jitter, calibration jitter and bit rate. The purpose of this calibration method is to solve the problems existing in the calibration process of digital TV code stream generator and to calibrate its technical characteristics more comprehensively. The calibration method has maneuverability and economy, and it is of great significance to ensure the quality of digital video products.
