Overview

Our broadband systems for dielectric and impedance material spectroscopy cover a frequency range of more than 16 decades from 3 μHz to 8 GHz.

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 .. 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 full automatically operated by the MS-Windows software package WinDETA. Further data evaluation like non linear curve fitting is supported by the WinFIT software.

Turn Key Dielectric / Impedance Spectrometers

• BDS Systems

  are dielectric / impedance spectrometers from 3 μHz .. 8 GHz without temperature control. They include an Alpha- and / or RF impedance analyzer, sample cell(s), WinDETA- WinFIT software and computer with GPIB card, monitor and printer (data acquisition unit).




• Concept Systems

  are based on BDS systems and extend them by one of our temperature control systems. Systems are turn key and rack mounted.




• RF Extension

  extends Concept systems with frequency range < 10 MHz to microwave frequencies up to 8 GHz. Adds an RF impedance analyzer, RF sample cell, RF extension line, RF mounting rack and WinDETA RF driver to an existing Concept system.
