Abstract

A low-frequency phase meter based on STM32 single-chip microcomputer is designed for the characteristics of expensive, complex functions and inconvenient portability of the phase meters on the market. The phase meter is mainly composed of STM32 single-chip microcomputer module, amplification and shaping module, display module, power supply module and so on. The article first introduces the design background and goals of the phase meter; secondly, introduces the overall design scheme and the selection of each module; thirdly, makes a real object for frequency and phase function tests; finally, makes a design summary. Experiments show that the frequency and phase measurement errors of the low-frequency phase meter are small, and the expected design goal is achieved. At the same time, the phase meter can measure a variety of waveforms, with low production costs and easy portability.
