Solartron - Model 1253A -Frequency Response Analyzer
Frequency range from 20 kHz to 10 µHz. Sine, square, triangle Voltage generator up to 10 V RMS and ± 10.22 V DC. Two (2) multiplexed Voltage measurement channels to 500 V peak. Transfer Function Accuracy to 1%, 1°. Able to perform DC potentiotstatic and galvanostatic experiments with 1287A Electrochemical Interface. Impedance range from 100 mOhm to 100 TOhm, with the 1296A Dielectric Interface.
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.
The 1253A Frequency Response Analyzer (FRA) is an instrument that is capable of meeting today`s measurement requirements for dynamic system analysis. Using the Single Sine Correlation technique (SSC), it provides precise data relating to the gain and phase between any points in a dynamic system. This instrument enables engineers to perform searching analysis to assess performance of both simple or complex systems.
