Resum

This paper presents a cost-effective solution for high-frequency signal acquisition using a subsampling-based system. The focus is on the practical implementation of a uniform subsampling setup, leveraging Track-and-Hold Amplifiers (THAs) and precise timing control for efficient signal reconstruction. The system allows the acquisition of signals above the Nyquist frequency, significantly reducing data storage needs, simplifying real-time analysis, and enabling the use of economically competitive components. Special attention is given to the challenges and considerations in deploying such a system, including the need for synchronization between THAs and the measurement system, and the impact of timing jitter. The paper demonstrates that with careful implementation, subsampling-based systems offer a promising and economically viable approach for high-frequency signal acquisition and control.
