Alpha-A Analyzer
Non Linear Dielectric, Conductivity, Electrochemical and Impedance
Spectroscopy
With the new Alpha-A series,
Novocontrol introduces a turnkey commercial solution for non linear
dielectric, conductivity, electrochemical and impedance spectroscopy. For
this purpose, the Alpha-A
mainframe and all test
interfaces (except G22) support measurements of the sample voltage and
current in terms of DC components, harmonic base waves and higher
harmonics up to the interface high frequency limit.
Non linear evaluation is fully supported by WinDETA software, which reads and graphically displays all voltage and current base, and higher harmonic components. In addition, other parameters like DC material parameters, linear impedance, permittivity, conductivity and the corresponding higher harmonic terms are processed.
The higher harmonic current components I*n(ω) are calculated by the Alpha analyzer like the base wave (n=1) by complex Fourier Transform from the sampled current i(t), where n denotes harmonic n-1.
.
Applications in impedance mode are characterization of non linear material - or component under test properties.
In gain phase mode, non sinusoidal signal components in the measured voltages are detected by harmonic analysis.
