With the continuous development of electronic testing technology, the limitations of traditional measurement instruments in terms of portability, integration, and flexibility are becoming increasingly apparent. To meet the demand for multifunctional, high-performance portable instruments in scientific research, education, and engineering fields, this paper proposes an integrated testing system based on FPGA—"Intelligent Measurement Wizard". The system innovatively integrates function modules such as signal generator, oscilloscope, and logic analyzer on a single platform, utilizing Ethernet communication to achieve high-speed data transmission while supporting real-time parameter adjustment and multi-board cascade expansion. Through the application of RISC-V soft-core transplantation and DDR3 storage technology, the system achieves 99% frequency accuracy, 15-35Msps sampling rate, and 4-channel logic analysis capability while maintaining portability. This paper will discuss the system architecture, module design, performance testing, and other aspects, providing new solutions for the development of portable testing instruments.
