<P>PROBLEM TO BE SOLVED: To provide a detection device capable of solving the problems that a method for using a network analyzer to adjust skew of a two-channel transmission signal generated from a signal generating device takes a lot of trouble and requires a large device configuration, an analog modulation circuit and a testing device. <P>SOLUTION: The detecting device for detecting skew of first and second analog signals supplied in parallel from a signal generating device to a signal processor is provided with a multiplying part for multiplying the first analog signal by the second analog signal outputted by the signal generating device, and a detecting part for outputting signal of a level corresponding to a skew value on the basis of a multiplication result in the multiplying part. In the detection device, the signal generating device may be further provided with a signal control part for outputting a first analog signal and a second analog signal having almost the same cycle. <P>COPYRIGHT: (C)2008,JPO&INPIT |
