Research on Calibration Method of Digital Video Analyzer
Through the study of digital video analyzer,the necessity of calibration is expounded,and according to the current calibration status,calibration items are proposed for the main measurement functions.The frequency counter and programmable digital video signal generator are used as the main standard.According to the measure-ment principle of video parameters and audio parameters,the process and calibration method of calibration signal are introduced and verified by experiment.
