摘要
Abstract
The structure of multi-channel arbitrary waveform generator (AWG) is analyzed, the methods for adjusting
phase difference between output signals are discussed, and then the resolution and range of each adjusting method are ob
tained. For the error produced by clock skew and channel delay in the design, a method of multi-channel AWG with phase
calibration module embedded is presented. The advantages and disadvantages of two correlation algorithms in measuring
phase difference are discussed. The correlation algorithm is carried after sampling two signals simultaneously for measur
ing phase difference. Then the experiments about controlling phase difference are conducted, and the results show that the
method is feasible.关键词
