NBM-520 Narda
1.1 Measuring electromagnetic fields
In today’s world, practically everyone lives and works in an
environment surrounded by technical equipment that gener-
ates electromagnetic fields. Our recognition of the problems
associated with such fields and our depth of information in
this area has increased as the effects of such fields on the
human body have been examined more closely. Various
authorities have long defined limit values designed to pro-
tect users from the dangers of exposure to such emissions.
1.2 About this instrument
The Narda Broadband Field Meter NBM-520 provides virtu-
ally everyone concerned with this subject with an instrument
for measuring non-ionizing radiation with utmost accuracy
within the frequency range from 100 kHz to 60 GHz
(depending on the probe used). The instrument features
very simple operation, a handy design in a robust casing,
long battery life, and high measurement accuracy.
Probes for various measurement applications are con-
nected to the NBM-520 basic unit. Flat frequency response
probes are available, as well as so-called shaped probes
that evaluate the field according to a specific human safety
standard. These probes are calibrated separately from the
measuring instrument, and include a non-volatile memory
containing the probe parameters and calibration data. They
can therefore be used with any instrument in the NBM-500
family without any loss in calibration accuracy.
The PC software supplied with the instrument allows you to
remote control the NBM-520 and to configure the instru-
ment settings.
Applications
The
NBM-520
makes precision measurements for human
safety purposes, particularly in workplace environments
where high electric or magnetic field strengths are likely. It
can also be used to demonstrate the electromagnetic com-
patibility (EMC) of devices and equipment.
