Problems solved by technology

However, when collecting these high-speed signals, some data is usually lost because the transmission rate of these high-speed signals is too fast or signal distortion occurs because the frequency of these high-speed signals is greater than the maximum operating frequency of the data acquisition interface, resulting in correct data acquisition. rate is not high

Abstract

A signal collection system comprises a signal sending module, a computer and a data collection card, wherein the data collection card is connected between the signal sending module and the computer, the signal sending module comprises at least one signal source and a delayed chip which is connected with the signal source, the delayed chip outputs a signal received from the signal source to the data collection card in real time and outputs the signal to the data collection card again after delayed process is carried out on the signal received from the signal source, the data collection card comprises an underclocking module, and the underclocking module carries out underclocking process on the signal collected by the data collection card and outputs the signal to the computer. The invention further discloses a signal collection method based on the signal collection system. The signal collection system and the method can collect data in a double mode, carry out the underclocking process on high-speed and high-frequency signals, and accordingly reduce the probability of data loss.

Description

technical field [0001] The invention relates to a signal acquisition system and method, in particular to a high-speed signal acquisition system and method. Background technique [0002] In quantum communication or other high-speed communication systems, multiple high-speed signals are usually transmitted at the same time, thereby increasing the data transmission volume and transmission speed. However, when collecting these high-speed signals, some data is usually lost because the transmission rate of these high-speed signals is too fast or signal distortion occurs because the frequency of these high-speed signals is greater than the maximum operating frequency of the data acquisition interface, resulting in correct data acquisition. The rate is not high. Contents of the invention [0003] In view of the above, it is necessary to provide a signal acquisition system and method with a high accuracy rate of data acquisition. [0004] A signal acquisition system, including a ...
