Most system operate in the frequency domain and measure directly the complex impedance of a sample capacitor as a function of frequency, temperature, ac voltage, dc bias, pressure and time (or any combinations of these quantities up to 4 dimensions). From the sample impedance, the other dielectric parameters like complex dielectric function or complex conductivity are calculated.
In addition, at frequencies from 1 MHz - 3 GHz, measurements of the magnetic complex permeability are supported.
Three temperature control systems from −160 °C to 400 °C are available as an option and maybe combined with any dielectric and impedance measurement system. For frequencies below 1 MHz, a high pressure - temperature control system and high temperature control systems up to 1600 °C are offered.
Thermally stimulated depolarization (TSDC) and time domain measurements can be added.
All systems are turnkey, modular and fully automatically operated by the Windows software package DETACHEM. Further data evaluation like non linear curve fitting is supported by the WinFIT software.
