Solartron 1260A Impedance/Gain-phase Analyzer (FRA)


Frequency response analyzers (FRAs) are often used to measure the complex impedance of materials. Used alone, they lack the sensitivity required for accurate measurements. The 1296A dielectric interface enhances the capabilities of Solartron Analytical’s 1260A FRA to cope with ultra-low current and capacitance levels. Key features of the system are,

• Impedance measurements to exceed 100 TΩ (1014Ω)

• Frequency range from 10 μHz up to 10 MHz

• Potentiodynamic impedance measurements with DC bias voltages up to 40 V.
