Network Analyzer Architectures
应用文章
Network analyzers have become one of the most important measurement tools for characterizing the performance of high-frequency components and devices. A modern vector network analyzer can measure a component’s magnitude, phase, and group delay, show port impedances on a Smith chart, and, with time-domain capability, show the distance from a test port to an impedance mismatch or circuit fault. Understanding a network analyzer’s capabilities and operation can help an operator derive optimum performance from the instrument.
