Applications and Software


The Model 1260A Phase Gain/Impedance Analyzer is undoubtedly the most powerful, accurate, and flexible frequency response analyzer available today. The 1260A's solid reputation, which leading researchers used on a daily basis where measurement integrity and experimental reliability are of paramount importance, is frequently supported by published research papers in fields such as:


  • Corrosion studies
  • Battery and fuel cell research
  • Solar cells
  • LCD
  • bio-materials
  • ceramics / composites
  • Development of electronic components
  • civil Engineering


huge frequency range
With a range of 10 μHz to 32 MHz with a resolution of 0.015 ppm, the 1260A offers excellent coverage for virtually all chemical and molecular mechanisms, all in a single instrument.


unmatched precision
With an accuracy of 0.1%, 0.1°, measurements can be made with complete confidence, and even the most subtle changes in sample behavior can be detected and quantified.


The noise-free analysis
The 1260A uses Solartron Analytical's patented Single Sine Correlation technique, which inherently eliminates noise and harmonic distortion that plagues lesser instruments.


  • Frequency Resolution: 1 in 65 million (0.015 ppm)
  • 0.1%, 0.1° accuracy - unsurpassed by any similar instrument
  • 0.001 dB, 0.01° resolution - capture every detail
  • Measures impedances >100 MΩ
  • 2, 3 and 4 terminal measurement configurations
  • Polarization voltage up to ±40.95 V
  • Renowned ZPlot software suite simplifies experiments and optimizes performance


When combined with other products in the Solartron Analytical range, including well-proven application software, the 1260A can form the heart of an advanced materials and electrochemical measurement system, to provide excellent accuracy, flexibility and reliability, even for the most complex research problems.


impedance measurement
Virtually all liquids and solids can pass current when a voltage is applied to them. If a variable voltage (AC) is applied to the material, the relationship between voltage and current is known as impedance._cc781905 -5cde-3194-bb3b-136bad5cf58d_The measured impedance varies with the frequency of the applied voltage in a way that is related to the properties of the liquid or solid. This may be due to the physical structure of the material, to chemical processes within it or a combination of both.


The advantages of impedance measurement over other techniques include:


  • Fast data acquisition
  • Accurate and repeatable measurements
  • non destructive
  • Highly adaptable to a wide variety of different applications.
  • Ability to differentiate effects due to electrodes, diffusion, mass/charge transfer by analyzing in different frequency ranges
  • Equivalent circuit/modeling techniques for detailed analysis of results
