Using Interference Analyzer 

 

Introduction 

Interference is becoming more prevalent in the wireless community with the increasing number of transmitters coming on the air. 
Wireless service providers have traditionally used spectrum analyzers to monitor service channels, frequencies, and adjacent 
spectrum and to locate sources of interference. A spectrum analyzer can only show you an interfering signal and you require 
determining the source of the interference. To solve interference problems, you must understand the RF environment, know 
adjacent operating transmitters, and identify any new or unlicensed emitters. 

Once a potential interfering signal is identified in the Spectrum Analyzer mode, you can monitor the signal further in the Interference 
Analyzer mode. CellAdvisor 5G provides two different methodologies to identify and determine interference signals: Spectrogram 
and Received Signal Strength Indicator (RSSI). Locating the source of interference signal can be done with geographical 
information received from the built-in GPS receiver. 

The CellAdvisor 5G is extremely effective for locating and identifying periodic or intermittent RF interference. Interference signals 
derive from several kinds of licensed or unlicensed transmitters that cause dropped calls and poor service quality. 

The CellAdvisor 5G provides following measurements for interference analysis with frequency extension up to 18.5 GHz in addition 
to existing 24 GHz to 40 GHz:

Using a set of the AntennaAdvisor Handle that holds a broadband directional antenna is mandatory in the Rader Chart mode and its 
built-in compass, GPS antenna, gyro sensor, and low-noise amplifier (LNA) benefits you to determine the direction of the 
interference. 

 

Selecting mode and measure 

To start measurement, do the following steps: 

1

      

Tap
