2-3 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.
