Frequency Response Analysis (also referred to as Transfer Function Analysis) measures the output spectrum of a system relative to a stimulus, and is used to characterize the dynamics of the system under test. The technique measures the magnitude and phase relationship between output and input waveforms as a function of frequency. The input signals may be from a wide range of sensors including acoustic (microphones/sonar), mechanical (accelerometers/displacement transducers), optical (photodetectors), and electrical (amplifiers).

Applications that make use of this powerful technique include - electrochemical impedance spectroscopy (EIS), materials analysis, aerospace control system design, electronic amplifier design, power supply design, and vibration analysis.

Systems
When combined with other products from Solartron Analytical’s range, including well-proven application software, the 1260A can form the heart of an advanced electrochemical and materials measurement system, to provide superb accuracy, flexibility and reliability - even for the most complex research problems.

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
