Description

Technical Field

[0001] The present invention relates to the technical field of vector network analysis, and specifically to a vector network analysis test system. Background Art

[0002] A vector network analysis instrument is a test device for electromagnetic wave energy. It can measure the amplitudes of various parameters of a single-port network or a two-port network, and can also measure the phase. The vector network analyzer can display test data using a Smith chart; a vector network analysis instrument is a test device for electromagnetic wave energy. A vector network analyzer is an instrument that uses its own signal source to measure the scattering parameters of RF and microwave devices, cable lines, connectors, etc. It combines various technologies such as spectrum analysis, signal generation, and signal separation, and is often used in the R & D testing and production manufacturing of basic industries and fields such as microwave devices, materials science, and electronic communication; the principle and use of a vector network analyzer directly depend on indicators such as the frequency range, trace noise, and dynamic range of the system; the test of the phase fluctuation parameter is achieved by using the Electrical Delay function of the vector network analyzer; directly observing the insertion phase shift is usually not very useful because the electrical length phase shift of the device shows a negative slope with respect to frequency (the longer the device, the greater the slope). Since only the deviation from the linear phase shift will cause distortion, it is desirable to remove the linear part of the phase response. By using the electrical delay function of the network analyzer, the electrical length of the device under test can be cancelled, and as a result, the deviation from the linear phase shift, that is, the phase fluctuation (distortion), can be obtained; the vector network analyzer can measure the amplitudes of various parameters of a single-port network or a two-port network, and can also measure the phase. The vector network analyzer can display test data using a Smith chart, which is more convenient for engineering applications and debugging.
