RF-VNA / RF - Vector Network Analysis
To characterise the response of a system in high frequency (up to GHz range), a Vector network analyser is typically used. The system will apply a known electrical stimuli of specific frequency and measure the reflected / absorbed voltage and phase. The resulting measurement presents a detailed electrical characterization of the system in terms of equivalent impedance of material under test as a function of frequency throughout the measured frequency range. This s commonly used to measure high frequency devices as well as measure the material properties in extended frequency ranges.
