Dielectric Probe Software

DAK Software

Flexibility and Precision (see DAK Intro Video)


DAK is designed to measure the dielectric properties of homogeneous and isotropic liquid, solid, and semi-solid materials. The sample volume should be large enough to ensure that reflections at the sample boundaries do not significantly influence the measurements. The minimum sample volume depends on the frequency, probe size, and dielectric parameters.

For data acquisition and visualisation the same graphical user interface is used for DAK, DAKS, and DAK-TL. For the measurement of thin layers, e.g., plastics and thin films, we developed enhanced algorithms which take into account the limited thickness of the material under test. 

VNA control and data acqusition is different in the case of DAK-TL-P and DAK-TL-P². For TL-P the software needs complex reflection coefficient data, e.g., S11. For TL-P² transmission is measured in addition (S11 and S21). The list of supported VNAs for TL-P² are different. 

Software Features

Accuracy: advanced algorithms for fast, high-precision measurements

Enhanced visualization: view your choice of parameters (ε', ε", σ, tanδ, μ', μ'') in a variety of formats (linear, log, Smith chart, tabular)

Robust data analysis suite: fit data to analytical curves, compare data with target parameters, and view tolerance and uncertainty ranges

Flexible scripting: control equipment and data analysis with built-in Python interface

Portability: import data in several formats; export data to DASY6 and SEMCAD X

Computer requirements: 

  • The software must run on an external computer, not on the VNA.
  • Intel Core2 Duo 2.3 GHz CPU (or AMD equivalent).
  • 2 GB of RAM.
  • 3D accelerated graphics display adapter card with 128 MB of on-board memory that supports the latest OpenGL drivers. (Note: graphics cards of the AMD Radeon™ HD 7500M/7600M Series must run on the latest driver version.) 
  • Operating system: Windows 10, Windows 8, Windows 7, or Windows XP (with Service Pack 3 and all recent updates). Windows 7 is recommended. The software v2 is running only on 64 bit Windows operating system.
  • A display with 32-bit color depth and a resolution of 1280 × 1024 pixels or better  (optimum size: 1920 × 1200 pixels).
