low-frequency digital phase-measuring instrument; This system consists of phase-measuring instrument, digital phase shifting generator and phase three network components. To make the system more stable, the overall accuracy of the system can be protected, the two T89C52 circuit control devices at the core respectively phase measurement control, digital believe the shift occurred, the digital shift occurred some believe that the use of lock-in technologies, such as CPLD technology, the output waveform accuracy greatly improved, and can automatic calibration frequency, frequency stability.
