Spectrum Monitoring
The Spectrum Manager has built-in tools to provide an excellent resource for examining, tracking, and troubleshooting the RF spectrum.

Use this feature to monitor the FM demodulated signal at a selected frequency.
Menu: Manual > Listen
• Use the control wheel to select the frequency and antenna for monitoring.
• The data display shows the signal strength of the selected frequency.
• The menu display shows the selected frequency and antenna.
• The Listen feature can also be accessed from the CFL > Edit menu,
allowing easy cueing of frequencies that are in use or backups.
Scanning
Performing a spectrum scan creates a plot of RF activity on the data display. Use the Cursor, Zoom, and Peak tools to examine a specific area of the plot. The Store op-
tion allows for 2 plots of scan data to be saved by the Spectrum Manager for reference or for CFL calculation. Scans initiated from the Spectrum manager menu cover the
entire tuning range. The Frequency Plot tool in Wireless Workbench software can be used to scan a subset of this range and provides options for step size and resolution
bandwidth.

Cursor adds a movable vertical dashed line
placed on the RF plot. Use the control wheel to
position the Cursor at any point in the plot.
The frequency value and signal strength for
the selected point are displayed at the top of
the plot.
During operation, the data screen tracks the status of frequencies available for Axient channels in the system. The
total number of frequencies available for each band are displayed, including real-time status of in-use and backup
frequencies. Backup frequencies which have been degraded by the monitoring function are removed from the
count of Ready frequencies.
• In Use = frequencies that are deployed to Axient components including off-line devices
• Ready = frequencies that are open and available for use as backups or for other components
• More = select to view additional frequency bands

1. Set the following modes:
• Sweep = Single or Continuous
• Peak Hold = Off or ON
• Exclusion Threshold = The Spectrum Manager excludes scanned frequencies above this value
from the Compatible Frequency List calculation. The threshold can be viewed during edit on the
Scan Data display.
2. Press Start to begin scanning. Scan progress is shown on the display. When finished press Store to
save a scan. Select Recall to access a stored scan. The recalled scan will overwrite the current scan
data.

Zoom magnifies RF plot to allow for detailed
analysis of a portion of the spectrum.
Use Zoom to identify individual frequencies in
crowded RF environments.

Peak enables the cursor to only select the
highest peaks of the RF plot.
Peak provides a quick way to identify the
strongest signals in the RF plot.
