Low-frequency digital phase tester, the design is given to SPCE061A Sunplus 16-bit single-chip microcomputer as the core of digital phase measurement and realization of the basic principles of the program. The system consists of phase-measuring instrument, digital shift believe that its generator and phase-shifting network of three modules, respectively, by two independent single-chip control and display functions. Using DDS technology to generate two sinusoidal signals, and by changing the data memory read start address to the realization of digital phase-shift function, with Ф-T transform technique to achieve the phase difference measurement, making accurate measurement resolution to 0.1 º , the measured frequency and phase difference value into the LCD display by adding infrared keyboard and voice broadcast function, the system has intelligent, user-friendly features.
