Device and method for generating multi-channel sine wave phase standard signals

The invention relates to a device and a method for generating multi-channel sine wave phase standard signals and belongs to the technical field of electronics. The device comprises two or more filter and amplification circuits, two or more digital-to-analog conversion circuits, two or more waveform memories, a logic control circuit, an address counter, a computer, a human-machine interface circuit and a clock circuit, wherein the number of filter and amplification circuits, the number of digital-to-analog conversion circuits and the number of waveform memories are the same; and the filter andamplification circuits, the digital-to-analog conversion circuits and the waveform memories are correspondingly matched with one another one by one. The device is stable and reliable and high in resolution and is not influenced by factors such as noise, distortion and the like, and can generate multi-channel sine wave phase standard signals with adjustable phase differences among channels, and drifting is avoided; the common address counter and the control logic circuit avoid influences of factors such as time base distortion, time base dithering, synchronous time delay error and the like on the phase difference; and the device has the characteristic that phase difference values can be reproduced at high precision.
