Abstract
A real-time triggering transmission delay measurement model and a data transfer model are proposed to solve the problem that the delay time of triggering instruction received by the data acquisition node in distributed test system is different and unknown. Furthermore, a high-precision time interval measurement method with the use of delay chain cycle comparison is proposed to achieve the propagation delay of the synchronous triggering pulse. The delay measurement provides high-precision delay data for subsequent calibration of the synchronization triggering error. The test results show that the proposed method can realize high-precision measurement of the synchronous triggering pulse transmission delay in distributed test system.
