1260A Frequency Response Analyzer
The 1260A Gain-Phase Analyzer (or Frequency Response Analyzer) is the cornerstone of FRA technology. The 1260A can be used as a stand-alone unit, but its applications to Materials is greatly expanded when combined with the 1296A Dielectric Interface. This solution measures at both high-frequency and high-impedance.

Impedance Measurement
Virtually every liquid and solid is able to pass current when a voltage is applied to it. If a variable (ac) voltage is applied to the material, the ratio of voltage to current is known as the impedance. The measured impedance varies with the frequency of the applied voltage in a way that is related to the properties of the liquid or solid. This may be due to the physical structure of the material, to chemical processes within it or a combination of both.
The advantages of impedance measurement over other techniques include: Rapid acquisition of data
Accurate, repeatable measurements
Non-destructive
Highly adaptable to a wide variety of different applications
Ability to differentiate effects due to electrodes, diffusion, mass/charge transfer by analysis over different frequency ranges
Equivalent circuit/modeling techniques for detailed analysis of results
