Figure E1: Initial Configuration

Step 1. Configure test equipment as shown in Figure E1.

Step 2. Program the initial Spectrum Analyzer settings, per the following:

A. Resolution Bandwidth= 100KHz

B. Video Bandwidth = 100KHz

C. Attenuation = 0db

D. Ref level = -10db

E. Sweep time = auto

F. Detector mode = positive peak

G. Frequency = will be determined at each point during the procedure.

Step 3. Set the frequency sweep range per the following.

A. 2.4GHz = sweep for ranges 2.390GHz to 2.5GHz

B. 2.6GHz = sweep for ranges 2.596GHz to 2.644GHz

Interference Sweep Procedure

The following information applies to both Panel and Omni antennas. It guides you through the steps

to capture data required for the interference study. The number of steps varies depending on the type

of antenna you are using and the frequency band you are investigating. If you are using an omni

antenna to perform this procedure, only one pass is required. If a directional antenna is used, the

number of passes through the procedure is determined by the beamwidth of the antenna.

When using a directional antenna to pick up the interference, try to change the angle or downtilt to

face a potential interference source such as a tower or a more populated area. A directional antenna

is used to determine the location of the source that is generating the interference. The beamwidth of

the directional antenna determines the number of directions that you need to sweep.

For example, if the beamwidth of the directional antenna is 90 degrees, then four passes of the

procedure are necessary. Whereas, an antenna with a 30-degree beamwidth requires 12 sets of
