1.2 About this instrument
Narda NBM-520 3
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.
Examples:
• Measuring field strengths as part of general safety
regulations
• Measuring the field strengths around transmitting and
radar equipment to establish safety zones and for
monitoring during operations
• Measuring the field strength emanating from mobile
phone repeaters and satellite communications systems to
ensure compliance with human safety limit values
• Measuring the field strength in the industrial workplace
environment, such as plastics welding equipment, RF
heating, tempering, and drying equipment
• Measurements to ensure the safety of persons using
diathermy equipment and other medical equipment that
generates high frequency radiation
• Field strength measurements in TEM cells and absorber
chambers
