The embodiment of the invention relates to the field of communication, and discloses a time delay measurement system, a time delay measurement method, electronic equipment and a storage medium. The time delay measurement system comprises a signal generation device and an oscilloscope, the signal generation device is connected with a to-be-tested time delay device and the oscilloscope, and the to-be-tested time delay device is connected with the oscilloscope; the signal generation device is used for generating a first reference signal according to the received first pulse width data and transmitting the first reference signal to the oscilloscope and the to-be-tested time delay device; the to-be-tested time delay device delays the first reference signal according to the set to-be-tested timedelay amount to generate a first time delay signal, and transmits the first time delay signal to the oscilloscope; and if the time delay difference value between the first time delay signal and the first reference signal is equal to the to-be-measured time delay amount, the end time of the first reference signal displayed in the oscilloscope is aligned with the start time of the first time delaysignal. According to the embodiment of the invention, the to-be-measured time delay of the to-be-measured time delay device can be accurately measured, and the time delay measurement cost is reduced.
Description
technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a delay measurement system, a delay measurement method, electronic equipment, and a storage medium. Background technique [0002] The principle of satellite and ground ranging is: by measuring the electromagnetic wave transmission delay between the satellite and the ground, the distance between the satellite and the ground is calculated. This ranging principle is widely used in manned spaceflight, lunar exploration, satellite communication and other national defense / communication fields. The verification of key indicators such as reliability requires a large number of high-precision delay simulations. The delay simulation determines the reliability of the key indicator verification. Therefore, it is necessary to measure the delay to ensure the accuracy of the delay. The channel simulator can generate a controllable time delay for the electromagnetic wave sign...
