Research on the Dynamic Range of High End Vector Network Analyzer

This article focuses on the basic concept of the dynamic range of vector network analyzers, the important factors that affect the dynamic range, and several main methods to improve the dynamic range. The dynamic range characterizes the ability of vector network analyzers to measure the transmission parameters of the DUT, and is one of the indicators that users are very concerned about. Especially in recent years, the improvement in the accuracy requirements of the DUT has put forward higher requirements for the dynamic range of the system. The same dynamic range can be tested with a larger intermediate frequency bandwidth, thereby improving the testing speed.
