Introduction

Many wireless networks operate in complicated signal environments. Three or four base station antennas may be located on the same tower, and can create interference problems, which can affect system capacity and coverage.

The Interference Analyzer (option 25) adds five measurement capabilities to the spectrum analyzer:

•	“Spectrogram”

•	“Signal Strength”

•	“Received Signal Strength Indicator (RSSI)”

•	“Signal ID”

•	“Interference Mapping”

The instrument also has a spectrum mode which displays signals in a traditional spectrum
analyzer view.

Note	Set the instrument to Interference Analyzer mode for all the measurements in this chapter.
