A VNA can also be used to measure the directivity of an antenna or the properties of dielectric materials.
A vector network analyser is used to measure transmission parameters, crosstalk, distance to fault (DTF) and other parameters.
Thus, unlike an SNA, the VNA, a more sophisticated instrument, can check the phase shift as a function of frequency, as well as the gain of an amplifier over a given bandwidth.
Unlike scalar array analysers (SNAs), which only measure the amplitude of the return signal, VNAs also measure its phase.
To perform a measurement, a signal is transmitted to the Device Under Test (DUT) and the Vector Network Analyzer (VNA) measures the response of the device under test.
These versatile instruments are used to characterise RF components, cables and antennas.
Vector Network Analyzers (VNAs) are test instruments commonly used in the radio frequency (RF) field both in manufacturing and maintenance sites and in laboratories.
