providing x1 , x2 , and x4 views, as a sizable map file so that you can zoom in and out
after loading it.
2.
Press SAVE/LOAD hot key, and then select Load > Load Map .
3.
Navigate to a map file you want to open.

If you have connected the AntennaAdvisor Handle, you must initialize it.
Procedure
1.
Press the MEASURE SETUP hot key.
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.
2.
To adjust the integration bandwidth based on the center frequency of the interfering signal that
you have identified in the Spectrum view, complete the following steps:
a. Press the Bandwidth soft key.
b. Enter a value by using the numeric keys. You can also use the rotary knob.
c. Select the unit option from the choices: GHz , MHz , kHz , and Hz .
3.
Initialize the antenna handle to calibrate the built-in compass by completing the following steps:
a. Hold your antenna handle horizontally in its upright position.
b. Point the antenna to the north, and then press the Initialize AntennaAdvisor soft key.
Setting location
As the Interference Finder uses triangulation to provide a circle of possible source of the interference,
you must set three location points so that the straight lines started from the point can create three
intersections. If you have the AntennaAdvisor Handle, it makes it easy to determine these points using
its built-in compass and GPS antenna while measure power level of the received signal.
Procedure
1.
Press the Location Setup soft key in the Measure Setup menu bar.
2.
Press the Location soft key to set three location points.
3.
Press the Point [1|2|3] soft key to set the first location point, and then do one of the following:

signal received by either the GPS antenna or AntennaAdvisor Handle.
–
To manually define a position for the selected point, complete the following steps:
a. Press the Latitude soft key, and then set the properties: North/South , Degree ,
Minute , and Second .
b. Press the Longitude soft key, and then set the properties: East/West , Degree ,
Minute , and Second .
4.
To set an azimuth, do one of the following:
–
Using the AntennaAdvisor Handle, complete the following steps:
a. Press and hold the TRIGGER button on the handle and pan the antenna handle to scan
through until you find the strongest RSSI value.
RSSI, polarization, elevation and azimuth readings are continuously updated on the
