Realization of a Low-frequency Phase Standard System
This paper is based on the digital waveform synthesis techniques, designed and implemented a new digital phase standard source. The amplitude, frequency and phase of the phase-source system can be adjusted, the output sine wave frequency ranges of ~10Hz ~ 100kHz and the phase adjustable ranges of -180 ~ 180 . By extending the voltage amplifier and transconductance amplifier, the voltage output can up to 600V, the current can up to 100A , the resolution can up to 0.0017 and the phase accuracy can up to 0.005 . This circuit design is simple, reliable, and can be controlled by programs well. So it can be applied for highly accurate calibration and test as standard sine wave signal source and phase source.
