Network Analysers

A Network Analyser is an instrument that measures the network parameters of electrical networks. The modern day network analysers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h-parameters. Network Analysers are often used to characterise two-port networks such as amplifiers and filters, but they can be used on networks with an arbitrary number of ports.
