Dual Channel Method for Attenuator Intermediate Checking
A fast and accurate attenuation value intermediate method,the dual channel method,is proposed for commonly used attenuators in electromagnetic compatibility laboratories.The core of the method is to use the power divider and the dual channel power meter to construct two identical measurement channels,eliminate the systematic error,and realize the intermediate checking of the attenuator.After comparison and analysis with the traditional verification method of vector network analyzer and the verification method of signal generator with measurement receiver,the accuracy and reliability of this method are verified.
