DAK (4 MHz - 67 GHz)

System

DAK consists of three single probes that cover the very broad frequency range from 4 MHz to 67 GHz without compromise on uncertainty. The probes are mounted on a mounting arm and connected via a high-quality cable to any vector network analyzer (VNA). DAK is designed to measure the dielectric properties of homogeneous and isotropic liquid, solid, and semi-solid materials.

Application

Application examples include:

• Characterization of materials for the electronics, chemical, food, and medical industries
• Measurement at high frequencies with excellent precision; broad frequency range coverage enables measurement of dielectric relaxation in a variety of materials

Calibration

Calibration is performed according to SPEAG's high-quality standards; DAK probe calibration included within the scope of SPEAG's ISO/IEC 17025 accreditation; suitable for measurements with small and known tolerances.

Verification

The DAK Verification Kit provides a quick and easy tool to verify the measurements made by the Dielectric Assessment Kit.

Accessories

SPEAG provides all DAK components and accessories necessary for high-precision measurements: 

• Shorting block
• Probe stand
• Metallic strip set (MSS)
• Thermometer
• High precision cables to connect probe beam to the VNA port

Software

The software provides the following functionalities:

• Modern intuitive graphical user interface (GUI)
• Choice of complex permittivity parameters (ε', ε", σ, tan δ) reported in a variety of data formats: linear plots, logarithmic plots, Smith charts, Cole-Cole plots, and tabular
• Robust data analysis suite enables data to be fitted to analytical curves and to be compared with target parameters with tolerance and uncertainty ranges
• Streamlines the workflow for dielectric measurements
• Fast and robust VNA control, data acquisition, and calculation of dielectric parameters
• Includes averaging function and numerical noise filtering
• Flexible scripting for measurement automation and hardware customization

Computer Requirements

The following computer requirements must be met:
