Impedance analyzer

An impedance analyzer is a type of electronic test equipment used to measure complex electrical impedance as a function of test frequency.

Impedance is an important parameter used to characterize electronic components, electronic circuits, and the materials used to make components. Impedance analysis can also be used to characterize materials exhibiting dielectric behavior such as biological tissue, foodstuffs or geological samples.

Impedance analyzers come in three distinct hardware implementations, and together these three implementations can probe from ultra low frequency to ultra high frequency and can measure impedances from µΩ to TΩ.
