Chapter 3 Using Interference Analyzer
Conducting interference measurements
Initializing AntennaAdvisor
Once you have connected the AntennaAdvisor Handle to your instrument, antenna
initialization is required to obtain the correct azimuth data. You need to initialize the
antenna handle to calibrate the built-in compass by completing the following procedure.
You can adjust bandwidth based on the center frequency of the interfering signal that
you have identified in the Spectrum view by tapping Setup > Bandwidth. A message
appears at the bottom of the screen to alert you if you have not performed initialization
of your connected the antenna handle set.
To initialize AntennaAdvisor
1
Hold your antenna handle horizontally in its upright position.
To avoid the unnecessary impact of an external magnetic field, position yourself
location where the value of magnetic field strength displayed on the instrument is
green.
2
Point the antenna to the north and tap Setup > Initialize AntennaAdvisor.
The message disappears, and the red line for the current antenna direction
moves to the 0° line and overlaps to let you know that the initialization was done
successfully.
Obtaining RSSI data
Once you have connected your antenna handle set and done necessary setups, you
can monitor the power level of the received signal, the amount of polarization, and
elevation level real time. Using the Trigger button on the antenna handle set, you can
plot the RSSI level through 360 degrees at your location.
To obtain RSSI data
1
When you have the green GNSS indicator, tap the GNSS icon on the side panel to
set your current location to the center of the radar chart. The latitude and longi-
tude information at the side of the display changes from "Unknown Position" to the
obtained position information.
2
Tap the Save Position icon on the side panel to save a position to recall for trian-
gulation in the Interference Finder mode and select one that you want to save.
3
Monitor the RSSI reading of the received signal. If the signal is weak, turn on the
LNA switch on the antenna handle set to improve S/N.

NOTE
It is recommended that you re-initialize the AntennaAdvisor Handle after mea-
surements to re-calibrate the compass when you notice that the red line on the
radar chart is not aligned with the north on the map, even though you are
pointing the antenna to the north.
