Research on the latest calibration technology of vector Network Analyzer

Calibration and error correction technology, as one of the key technologies for vector network analyzer to achieve high precision measurement, has always been the focus of researchers’ continuous efforts to explore and innovate. With the development of microwave network analysis theory and technology, vector network analyzer calibration and error correction technology in the measurement speed, accuracy, usability, adaptability and other aspects have undergone fundamental changes. In this paper, the latest development of vector network analyzer calibration and error correction technology is described in detail. New calibration technology not only enhances vector network analyzer error correction function, and expands the vector network analyzer applications - including not only multiport devices, some special test environment and test problems of traditional S parameter linear test areas, including chip, fixture and on-wafer such as microelectronic test in field, It also includes mixer and power amplifier gain compression, intermodulation and other nonlinear characteristics testing fields. At the same time, the intelligent and automatic calibration mode represented by electronic calibration technology pushes the vector network analyzer calibration and error correction technology to another height
