In order to increase the standard equipment of the time interval, the data generator is adopted as a precision delay device. Based on the analysis of data generator principles, the formula describing the relationship among the data output time, storage digit and crystalloid period is put forward, and a method of generating precision delay pulse by using data generator is proposed. The validation experiment indicates that the proposed method can achieve the function of precision delay using current data field equipment and extend the application range of data generator.
