1253A - Frequency Response Analyzer

The 1253A Frequency Response Analyzer has a range of 300 V and up to 20 kHz



  • 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) voltage measurement channels multiplexed to 500 V peak
  • Transfer function accuracy to 1%, 1⁰
  • Capable of performing DC potentiostatic and galvanostatic experiments with the 1287A electrochemical interface
  • Impedance range from 100 mOhm to 100 TOhm, with the 1296A dielectric interface


Applications and Software


The 1253A Frequency Response Analyzer (FRA) is an instrument capable of meeting today's measurement requirements for dynamic systems analysis. Using the Single Sine Correlation (SSC) technique, it provides accurate data related to gain and phase between any point in a dynamic system. This instrument allows engineers to perform search analysis to assess the performance of simple or complex systems.



  • AC Amplitude Range - 0 to 10.23 V rms
  • Sine, square, and triangle waveforms
  • Frequency range 1 mHz to 20 kHz
  • Transfer function accuracy 1%, 1°



Transfer function analysis of control systems
Used independently, the 1253A is commonly used to characterize:


  • Automated test systems
  • power supplies (PSU)
  • Aircraft Instrumentation/System Controls
  • aerodynamic tests
  • weapon guidance systems
  • Vectoring and rocket propulsion technology


The 1253A in conjunction with a 1287A Potentiostat/Galvanostat can be used to measure the impedance of electrochemical cells. Typical applications include:


  • Corrosion studies and inhibitors
  • Fuel Cell Testing and Battery Research
  • Characterization of thin films and coatings
  • electroanalytical systems


materials science
Material and component impedance measurements can be made with a 1253A interface plus a 1296A or 1294A. Applications include:


  • Tests of dielectric materials (dielectric constant, permittivity, tan-delta, dielectric loss)
  • Characterization of fuel cell components
  • Analysis of curing and polymerization reactions.
  • Charge Transport in Semiconductors, Organic Crystals, and Ceramics
  • Bioimpedance tests on living subjects
