Systems for Electronic & Control System Studies

Solartron Analytical Frequency Response Analyzers are widely used for testing the phase and magnitude transfer function of both purely electrical and mixed systems. In these experiments the FRA's generator output (essentially a sinusoidal oscillator) is connected either directly to the system under test, or via an electromechanical transducer (e.g. a solenoid). The response of the system to the applied oscillation is then connected, either by direct electrical connection or via another transducer (e.g. a microphone) to the analyzer input of the FRA.

The overall transfer function of the system can then be measured over the operating frequency range of the FRA.

Typical applications include:

• Transfer functions involving an electrical response, e.g. resonators (crystal, ceramic, supersonic), magnetic head (audio, video) delay lines, capacitors/varistors/resistors, piezo/ferroelectric materials, communication cables, switched mode power supplies
• Transfer functions involving a non-electrical response, e.g. electrohydrodynamical
• Transfer functions involving a non-electrical perturbation, e.g. mechanical, pressure, temperature, magnetic field
• Transfer functions involving both non-electrical perturbation and response, e.g. photoelectrochemical impedance spectroscopy
