IXTL-010 DiLine Dielectric Measuring Kit 300MHz-6GHz

 

DiLine  dielectric test  kit measures the permittivity and conductivity of tissue simulant fluids and gels over a frequency range of 300MHz- 6GHz with an accuracy of +/-2%, and a repeatability of better than +/-0.1%.

Wide frequency range 300MHz-3GHz (3-6GHz option)

• Based on method referenced in IEC62209 and IEEE1528 SAR measurement standards

• Low uncertainties help reduce overall SAR measurement uncertainty

• Absolute (not relative ) measurement, does not require standard reference materials

Description

TEM cell technique measures Conductivity and Relative Permittivity of liquids and gels with high accuracy

IndexSAR have developed a dielectric measurement system Diline (see separate datasheet). The Diline uses TEM lines and is based on a technique by Toropainen et. al, This is one of three methods recommended in the FCC  SAR standard. The TEM approach is preferred on the basis of its accuracy of +/- 1.4% for permittivity and +/- 2.0% for conductivity, an improvement on coaxial methods that give relative results and are positionally dependant. The Diline TEM line sensor technique is an absolute method not requiring calibration with other liquids of known dielectric properties. Each TEM line sensor employed and the software algorithms utilised have been verified by performing tests on known reference liquids

DiLine is designed to make the measurement of a fluid’s permittivity and conductivity as simple and accurate as possible, with a minimum of prior training.

Four different lengths of sensor are provided to combat the variation of insertion loss with frequency, and an intuitive graphical results interface allows fluids to be assessed in seconds, both against reference values and previous measurements in an audit trail

DiLine works in combination with all major vector network analysers

 The hardware is designed to make the measurement process as simple as possible whilst software features enable flexible processing of measurement data and comparison (in percentage terms) with target values for simulant liquids properties or comparison with reference liquids for checking the accuracy of the method. A vector network analyzer is used to determine the change in transmission loss and phase of the supplied strip-line (TEM) sensors when filled with the liquid or gel under test. Three different lengths of sensor (300 to 3GHz) are provided to account for the variation of loss with frequency for a range of different liquids. An optional sensor IXTL-030 can be supplied to cover the frequency range 3-6GHz

Applications include the routine measurement of tissue-simulant liquids and gels used for Specific Absorption Rate (SAR) testing. Probes can be used with most models of Vector Network Analysers – with S parameter measuring facilities.
