Laboratory measurements

The Gabriel-Tech GmbH has its products regularly analyzed in the laboratory with respect to their efficiency in order to offer their customers always the same maximum quality. These laboratory measurements are performed by the independent Geophysikalische-Forschungs-Gruppe e.V.. Besides the regular testing of the existing range of products the effectivity of newly developed Gabriel-products is tested before they are introduced into the market. Moreover, the efficiency of the actual products is repeatedly tested with respect to newly developed devices in the field of mobile communications.

The Geophysikalische-Forschungs-Gruppe e.V. uses in its laboratory measurements a unique and high quality measuring and analyzing system to describe the efficiency of dejam procedures within the electric-, magnetic- and electromagnetic range. This system garantees (independent on measuring time and measuring place) that the effects of interferences and dejam procedures can regularly be repeated and estimated by changes of the EMI-potential.

Standardized measuring set up with separate field charging

Separate potential free measurements of alternating electric fields (low frequency) and constant magnetic fields (magnetostatic) within a 25 grid field are performed. The corresponding values along the x-, y- and z- axes are used to automatically calculate and document via a specific software the space values as isotropic substitute values. The substitute values of both screen fields are subsequently set off against each other and graphically presented in a 25 screen-dual-field.

A screen-dual-field mathematically put to “zero” serves as smoothed norm-field. The respective calculated dual-field-graphics refer to this.

Pre-measurements (without dejam product)

Grafic presentation of the Electro-Magnetic-Interference-Potential (EMI-Potential) relative to the norm-potential (in µW/m² ; low frequency). The measurements take place in a mathematically straightened norm-field using a Test-SIM-card, with the used Test-SIM-card always sending at maximum to produce comparable high frequency emissions.

Post-measurements (with dejam product)

Graphic presentation of the Electro-Magnetic-Interference-Potential (EMI-Potential) relative to the norm-potential (in µW/m² ; low frequency). The measurements take place in a mathematically straightened norm-field using a Test-SIM-card, with the used Test-SIM-card always sending at maximum to produce comparable high frequency emissions.

Pre-measurements (without dejam product)

Grafic presentation of the Electro-Magnetic-Interference-Potential (EMI-Potential) directly measured at a norm dummy head relative to the norm-potential (in µW/m² ; low frequency). The measurements take place in a mathematically straightened norm-field using a Test-SIM-card, with the used Test-SIM-card always sending at maximum to produce comparable high frequency emissions.

Post-measurements (with dejam-product)

Grafic presentation of the Electro-Magnetic-Interference-Potential (EMI-Potential) directly measured at a norm dummy head relative to the norm-potential (in µW/m² ; low frequency). The measurements take place in a mathematically straightened norm-field using a Test-SIM-card, with the used Test-SIM-card always sending at maximum to produce comparable high frequency emissions.
