This instrument is used to measure the impedance across its terminals, for instance in an RF circuit or a resonance circuit such as an antenna. The circuit being measured on is called a network. Since impedance is frequency dependent, the instrument sweeps across a range of frequencies. The instrument inputs a signal of the given frequency into the network, and measures the response. The same operation is repeated for many different (a spectrum of) frequencies. This is called a sweep. 

It measures S-parametersDette instrumentet brukes til å måle impedansen, til RF kretset. Den måler S parametre.
