While a professional spectrum analyzer provides higher levels of control and precision for pre-
planning, the Spectrum Analyzer page allows evaluation of the RF spectrum as seen at the radio’s RF
input port prior to deployment. This is useful for pre-planning the center frequency and occupied
bandwidth, and to determine polarization and antenna type and mounting locations.
For troubleshooting, enable the spectrum analyzer to scan the desired segment or full band of the
frequency range. Select the step size and set the remote radio transmitter ON or OFF. This allows
viewing of the clean spectrum without the remote transmitter on and a comparison of the remote
transmitter in the midst of other signals.
Use the smallest step size to obtain the finest view of the spectrum. The spectrum analyzer can be set
to match the start and stop frequency for a dwell mode. Peak and average detection modes are also
available. Peak detection is helpful for capturing intermittent events such as pulsed emissions.
It is best to set the Scan Time option to a time value as opposed to using the ‘infinity’ setting. If your
management computer is connected to the radio through the radio link, access to the GUI is interrupted
during the duration of the analysis.
The spectrum analyzer graph displays received signals in red or green (Figure 58), normalized in dBm
to the resolution bandwidth of the analyzer. Red indicates a peak hold function. This is the highest
level detected during the entire scan. Green indicates the last value measured at that frequency.

A completely green vertical box indicates that the signal maintained a steady level for the entire scan
or that the last scan measured at a strong or stronger level than the rest of the analysis. A completely
Note: Enabling the spectrum analyzer interrupts all radio traffic for the duration of the
analysis. In addition, access to the radio’s GUI may also be interrupted, depending on the
location of the interfaced computer relative to the radio where the spectrum analysis is
occurring. The GUI is available at the completion of the spectrum analysis.
Note: The result of selecting infinity may be complete loss of contact to that radio and may
require a physical visit to the radio location to disable the spectrum analyzer.
