Using Spectrum Analyzer tool
The integrated spectrum analyzer can be very useful as a tool for troubleshooting and RF planning, but
is not intended to replicate the accuracy and programmability of a high-end spectrum analyzer, which
sometime can be used for other purposes.
The AP/BHM and SM/BHS perform spectrum analysis together in the Sector Spectrum Analyzer tool.
Caution
On start of the Spectrum Analyzer on a module, it enters a scan mode and drops any RF
connection it may have had. When choosing Start Timed Spectrum Analysis, the scan is
run for time specified in the Duration configuration parameter. When choosing Start
Continuous Spectrum Analysis, the scan is run continuously for 24 hours, or until stopped
manually (using the Stop Spectrum Analysis button).
Any module can be used to see the frequency and power level of any detectable signal that is within,
just above, or just below the frequency band range of the module.
Note
Vary the days and times when you analyze the spectrum in an area. The RF environment
can change throughout the day or throughout the week.
Mapping RF Neighbor Frequencies
The neighbor frequencies can be analyzed using Spectrum Analyzer tool. Following modules allow user
to:
• Use a BHS or BHM for PTP and SM or AP for PMP as a Spectrum Analyzer.
• View a graphical display that shows power level in RSSI and dBm at 5 MHz increments throughout
the frequency band range, regardless of limited selections in the Custom Radio Frequency Scan
Selection List parameter of the SM/BHS.
• Select an AP/BHM channel that minimizes interference from other RF equipment.
Caution
The following procedure causes the SM/BHS to drop any active RF link. If a link is dropped
when the spectrum analysis begins, the link can be re-established when either a 15 minute
interval has elapsed or the spectrum analyzer feature is disabled.
Temporarily deploy a SM/BHS for each frequency band range that need to monitor and access the
Spectrum Analyzer tab in the Tools web page of the module.
