Design and Implementation of 5GSPS High-Speed High-Precision Data Acquisition and Signal Synthesis Module

Radar signal test systems have the ability to capture broadband signals in real time, analyse high-speed data streams and synthesise large bandwidth signals. The traditional test system is usually built with separate instruments and equipment, which makes it difficult to unify the indicators among the equipment, occupies a large space, has a complicated debugging and testing process, and has low system testing efficiency. Based on the characteristics of the standardised structure, a modular instrument that integrates high-speed and high-precision data acquisition and signal synthesis, and digital signal processing functions is designed and implemented, which improves the functional scalability and portability of the test system, perfects the performance of the radar test system and enhances the test efficiency.
