Frequency Response Analyzers

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.
