Network analyzers are used mostly at high frequencies operating frequencies can range from 1 Hz to 1.5 THz. Network analyzers are often used to characterize two-port networks such as amplifiers and filters, but they can be used on networks with an arbitrary number of ports. Today, network analyzers 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. ZVA40 vector network analyzer from Rohde & Schwarz.Ī network analyzer is an instrument that measures the network parameters of electrical networks.
