Solartron 1250E Frequency Response Analyser

Solartron Analytical

1250E Frequency Response Analyser

FRA for impedance measurement

Measure gain and phase with the 1250E Frequency Response Analyser from Solartron Analytical (Ametek).

How it Works

A sinewave is used to stimulate the device, and the response is analysed at various points in the system. This data is correlated with the stimulus to calculate the amplitude and phase relative to the generator. The ratio of the two measured signals is then used to find the system transfer function.

This process rejects all harmonics. It can even measure signals buried in noise, by increasing the integration time to reject interference.

The 1250E has a 300 V range, which is ideal for testing fuel cell stacks and high voltage batteries, such as those used in hybrid vehicles and residential power supplies.

Key Features

  • 10 mV to 10 V AC amplitude range for testing power supplies
  • 30 mV – 300 V analyser range for ATS (Automated Test Systems) and power station vibration testing
  • Noise rejection functionality
  • Synchroniser option – lock generator and carrier signals to external signals regarding frequency / phase
  • Analyse non-linear systems (harmonic analysis)
  • Front panel or PC software control
  • Modulator / demodulator option for interfacing with AC carrier systems

Applications

Electrochemistry

Measuring impedance is important when studying electrochemical/biological phenomena and material properties. Together with a potentiostat such as the 1287A potentiostat/galvanostat, the 1250E can be used for these electrochemistry applications:

  • Corrosion and inhibitor research
  • Coatings and films (organic and inorganic)
  • Solid electrolytes for oxygen sensors/fuel cells
  • Anode/cathode materials and electrolyte development
  • Bioanalytical research into the properties of plants and soil

Materials Testing

Combine with a 1296A Dielectric Interface and temperature test equipment to test a wide range of materials:

  • Battery, fuel cell and supercapacitor materials
  • Charge transport in semiconductors, organic crystals, ceramics etc
  • Chemical reactions, polymerisation and curing processes
  • Gas and liquid sensors
  • Ferro/piezoelectric and semiconductor materials

Control Systems

Frequency response analysers are often used to generate a signal. This is connected to a signal converter (eg hydraulic, pneumatic or electrical), which causes a controlled movement (eg displacement transducers in aerodynamic tests). These are placed on the system under test. The output signal is fed back to the FRA via a sensor, such as an accellerometer or displacement transducer. The system can then be characterised. This type of test is useful in these areas:

  • Automated test systems
  • Power supplies
  • Aircraft instrumentation and system controls
  • Aerodynamic tests eg studying applied forces to wing structures
  • Automotive shock absorbers
  • Weapons guidance systems
  • Rocket propulsion and vectoring technology
