Chapter 12 EMF (EMI) Operation
Connecting the antenna
196 9102 Handheld Spectrum Analyzer Software version 5.31
Connecting the antenna
As a first step you establish the appropriate hardware setup for the EMF
measurement according to measurement type. As explained before
the type of antenna you use depends on measurement type and
measurement method. For further details on which antenna to use
refer to “EMF measurements” on page 183 and “Measurement
antennas” on page 188.
Connecting the 9170
Biconical Antenna
To establish a connection between the 9102 and the 9170 Biconical
Antenna simply connect the antenna via an RF cable to the 9102’s RF
in connector.
Connecting the 9171
Isotropic Antenna
To establish a connection between the 9102 and the 9171 Isotropic
Antenna connect the antenna directly to the 9102’s RF in connector
and connect the controller cable to the 9102’s Multi Port connector. As
soon as you have connected the antenna to both connectors the 9102
automatically detects the antenna and loads the correction data.
After the antenna is detected and the correction data are loaded the
9102 switches to the Level menu and the
Antenna Factor softkey is
highlighted. To activate the antenna factor press the
Antenna Factor
softkey until
on is highlighted.
Connecting a directional
antenna
To establish a connection between the 9102 and one of the two direc-
tional antennas, the 9172 or 9173 Directional Antenna, simply connect
the antenna via an RF cable to the RF 9102’s RF in connector.
Using a tripod As a measurement antenna accessory Aeroflex offers a wooden tripod.
For ordering details refer to “Options and accessories” on page 5.
Using this tripod you can for example set the 9170 Biconical Antenna
up for turning. For setting up the appropriate antenna on the tripod, first
fix the appropriate adapter on the tripod and then fix the antenna to the
adapter. Then you can use the appropriate extension cable to connect
the antenna to the 9102. In case of the 9171 Isotropic Antenna you also
have to connect the controller cable to the 9102’s Multi Port as
described in “Connecting the 9171 Isotropic Antenna” on page 196.
NOTE
If you connect the antenna controller to the instrument with the EMF
(EMI) mode already running, it takes about 10 seconds for the 9102
to detect the antenna. In order to avoid any disturbance of the pro-
cess do not press any buttons on the instrument during this time.
