Chapter 11 Using EMF Analyzer
Introduction
Introduction
Base stations emit electro-magnetic fields (EMF) of high frequency, which varies
between wireless technologies and countries. As personal exposure to high frequency
fields from base stations can provoke health effect, the International Commission on
Non-Ionizing Radiation Protection (ICNIRP) has provided general guidelines on limita-
tions regarding high frequency exposure. Using the EMF Analyzer in JD700B series
with an isotropic antenna connected, you can now measure the level of EMF onsite in
the field in order to verify if the level of emission from of your base station is compliant
with the guidelines.
The EMF Analyzer can perform the following measurement and analysis:
•
Spectrum Analysis
–
•
Signal Analysis
–
Connecting antenna
In the EMF Analyzer mode, connecting an isotropic antenna (omni antenna) or a log-
periodic antenna (yagi antenna) is mandatory. Using these antennas, you can make
three-dimensional measurements.
To connect an isotropic antenna
1
Connect the RF Type-N connector of the isotropic antenna to the RF In port of
the instrument.
2
Connect the USB plug of the isotropic antenna to the USB Host port of the
instrument. The device icon appears in the system status bar on the screen.
