2 NBM-550 Narda
1.1 Measuring electromagnetic fields
In today’s world, practically everyone lives and works in an
environment surrounded by technical equipment that
generates 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 protect users from the dangers of exposure to
such emissions.
1.2 About the NBM-550
The Narda Broadband Field Meter NBM-550 provides
virtually 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 has
a wide range of functions, yet it is very easy to use. It also
features a handy design, robust casing, long battery life, and
high measurement accuracy.
Probes for various measurement applications are
connected to the NBM-550 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-550 as well as to export saved
measurement data and to analyze the results.
