Atec Narda-HF3061 - Manual

H-FIELD PROBE
HF3061
Measuring magnetic fields
from 300 kHz to 30 MHz
using instruments in the NBM-500 family
Public and occupational field exposure from
broadcasting, telecoms, and industrial
equipment
Isotropic (non-directional) measurement
62 dB dynamic range without changing
measurement range
The probe contains three orthogonally arranged coils 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 magnetic fields from 300 kHz to 30 MHz, such as
those caused by short and medium wave transmitters, many RF
communications services, and industrial equipment. The dynamic range
from 0.012 A/m to 16 A/m (62 dB) makes it ideal for measuring field
exposure in both the public and the occupational environment.
PROPERTIES
The probe has mechanical and electrical properties that are ideal for
field use. The sensors are effectively protected by impact resistant
plastic. The electric destruction limit is above 35 A/m for continuous
wave signals, which is several times more 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.
