Automated double frequency test system

This paper presents the basic principles of a method for the double frequency testing of receivers. This method makes possible the automated control of the characteristics and parameters of the electromagnetic compatibility of receivers as well as highly informative visualization of control results. Possible ways to implement the method for double frequency testing with the use of the automated double frequency test system (DFTS) built around conventional controlling and measuring equipment are outlined. Basic functionalities of the method for double frequency testing, which make possible automated detection and identification of all possible paths of the interference impact on the receiver antenna input and measurement of their parameters are described. Results of practical implementation of this method are discussed
