Features

This meter is a broadband device for monitoring high-frequency radiation in the specific ranges of

900MHz, 1800MHz, and 2.7GHz. Other measurements can be made, for reference purposes

only, using the entire range of 50MHz to 3.5GHz. The non-directional electric field and high

sensitivity also allow measurements of electric field strength in TEM cells and absorber rooms.

The unit of measurement and the measurement types are expressed in units of electrical and

magnetic field strength and power density.

At high frequencies, the power density is of particular significance. It provides a measure of the

power absorbed by a person exposed to the field. This power level must be kept as low as

possible at high frequencies. The meter can be set to display the instantaneous value, the

maximum value measured or the average value. Instantaneous and maximum value

measurements are useful for orientation, e.g. when first entering an exposed area.

 Measurements in the specific frequency ranges of 900MHz, 1800MHz, and 2.7GHz

 For isotropic measurements of electromagnetic fields

 Non-directional (isotropic) measurement with three-channel measurement sensor

 High dynamic range due to three-channel digital processing

 Configurable alarm threshold and memory function
