JD700B Series User’s Guide
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 limitations 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 JD700B series is the solution to perform following measurement and analysis:
◼
EMF Spectrum
◼
EMF Replayer

Connecting an isotropic antenna
In the EMF Analyzer mode, connecting an isotropic antenna is mandatory and the part number is
G700050380. Using this isotropic antenna, you can make three-dimensional measurements.
Procedure
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 JD700B series.
The device icon appears in the system status bar on the screen.
