UTILIZING HIGH FREQUENCIES
PROTECTION FROM HIGH FREQUENCIES
High frequency electromagnetic fields can be utilized in a
variety of ways. They are the means of broadcasting radio
and TV programs. They can be used to transmit voice signals for companies, rescue services, and private mobile
communications. They can locate aircraft. They can weld,
harden and dry materials in industrial production. They are
useful tools in medical diagnostics and therapy. And, they
heat up your food for you in the microwave oven.
High frequency electromagnetic fields affect humans and
the environment. National and international organizations
have specified limit values to provide protection from dangerous exposure levels. The NBM-500 series of broadband
field measuring sets from Narda Safety Test Solutions are
designed to measure the exposure and show whether these
limit values are being adhered to.
SAFETY IN HIGH-FREQUENCY ELECTROMAGNETIC FIELDS
Example: Safety zones around mobile
phone antennas. You can easily read
off the field strength value, and the
device warns you immediately if the
limit value is exceeded.
Example: Safety when working on
transmitter towers. The field strength
can be checked with the probe before you approach the vicinity of the
antenna.
Example: Public safety. The probes for
the NBM series are so sensitive, that
they can also easily detect the lower
limit values set for the general public.
Memory functions allow for long
term monitoring.
Example: Industrial workplace safety.
The NBM instruments are robust
enough to withstand external stresses
easily.
NBM-520:
FOUR BUTTONS FOR RESULTS
NBM-550:
THE EASY WAY TO FINE DETAIL
This handy device immediately displays the field strength in
V/m, A/m, mW/cm2, W/m2 – or directly as a percentage of
the permitted limit level if you are using a shaped probe. It
can be remote controlled or pre-configured for measurements from a PC via the optical interface.
This device offers additional convenience in the form of onsite evaluations and a memory for up to 5000 results, so you
can analyze and document the results later.
THESE DEVICES GO ANYWHERE
The NBM-500 series of
broadband field measuring
sets can cope with practically
any environment. The casings
are impact resistant, the probes are robust. The monochrome backlit LCD panels
can be easily read in darkness
or in sunlight. So, you get
reliable results, even under
difficult operating conditions.
PROBES FOR
EVERY
APPLICATION
The NBM probes for electric
and magnetic fields taken
together cover a frequency
range from 100 kHz to 60
GHz. Shaped probes weight
the field strength automatically according to the safety
standard.
All NBM probes are isotropic,
i.e. they are non-directional.
You don’t have to worry
about where the field is
coming from; just point and
measure.
THE FAMILY:
COMPLETELY COMPATIBLE
NBM basic units and probes are calibrated separately. The
probe data is saved in an EPROM within the probe; the
NBM basic unit takes this into account automatically. So
you can combine any NBM basic unit with any NBM probe
without any problems.
The NBM-520 can be controlled from
an NBM-550, turning it into an extended probe “handle”. In this way,
you can get the probe into awkward
corners but still read off the results
comfortably from the display of the
NBM-550 held in your hand.
KNOW WHERE YOU STAND: GPS
The NBM-550 supplies a
timestamp of the date and
time automatically for every
measured value. The GPS
option provides the location
coordinates. The GPS receiver
is simply plugged onto the
instrument and connected up
via the USB socket.
MAKE A RECORD
OF WHAT YOU
HAVE:
PC SOFTWARE
NBM-TS, the PC software for
the NBM family, is included
with the instrument. Since
the software is for the entire
family, you just install it once,
learn how to use it once, and
then use it for everything.
You can record your own voice comments and replay them over the
earphone. Each comment is stored
with the corresponding measured
value. It can be transferred to a PC
with the results and played back
using the PC’s sound card.
