E-FIELD PROBE
EF0391
Measuring electric fields
from 100 kHz to 3 GHz
using instruments in the NBM-500 family
General public and occupational field
exposure from broadcasting, telecoms and
industrial equipment
Isotropic (non-directional) measurement
64 dB dynamic range without changing
measurement range
Maximum sensitivity starts at 0.2 V/m
The probe contains three orthogonally arranged dipoles with detector
diodes. The three voltages, corresponding to the spatial components,
are available individually at the probe output. The NBM basic unit
calculates the resulting isotropic field strength.
APPLICATIONS
The probe detects electric fields from 100 kHz to 3 GHz, covering the
fields that occur in broadcasting, telecoms, and industry. The high
sensitivity of 0.2 V/m and excellent linearity make it ideal for measuring
human safety limit values in the general public domain.
PROPERTIES
The probe is designed with mechanical and electrical properties ideal for
field use. The probe head is made of foam material to provide effective
protection for the sensors, while having excellent RF characteristics.
The electric destruction limits for pulsed and continuous wave signals
are several times higher than any of the human safety limit values.
CALIBRATION
The probe is calibrated at several frequencies. The correction values are
stored in an EPROM in the probe and are automatically taken into
account by the NBM instrument. Calibrated accuracy is thus obtained
regardless of the combination of probe and instrument.
