N2 - Based on the digital sampling technology, a new broadband phase difference calibration device is developed. The DFT and interpolation compensation algorithms under non-integer period sampling are used. The construction, sampling strategy and compensation algorithm of the calibration device are introduced in detail. Its uncertainty is evaluated and verified by experiments. The frequency of the device covers 10Hz∼100kHz and the best measurement uncertainty on the phase difference is 0.0006°.
