Parameter Description
Grid Frequency Set the central operating frequency for the highlighted frequency
channel
RSSI mode Select the gradient-color type for the “Max RSSI” values to be
displayed on the Spectrum Analyzer output screen
The options are:
Normal (by default)
Gradient
Max Hold – holds the maximum signal values at a given
point
Peak Hold – holds the peak signal values at a given point
Scan mode "Local mode"– scanning is performed only on the local device.
"Combined mode"– Scanning is performed simultaneously on all
devices in the sector. The "Last Snapshot" button will display the
blended result
32 Table - Spectrum Analyzer
Start/stop Spectrum Analyzer by clicking the «Start Sensor Test»/«Stop Sensor Test» buttons.
By clicking the «Last Snapshot» button, you get the final scanning results. The most common usage of this feature
is when you perform a spectrum scan at the remote unit on the other side of the radio link. When running a
spectrum scan at such a unit (accessible via the RF interface), connection to this unit will be lost for a scan time.
"Last Snapshot" option allows viewing scan results when the connection gets up again.
When you run spectrum scan on a local unit and the link is interrupted, the remote unit will not disappear from the
spectrum picture. So you should silence the remote unit in order to have a real picture without it, otherwise you will
always see noise signal on the operating frequency generated by the remote unit.
You can get detailed information about the scanned radio signals on a specific frequency. Just point a cursor on the
needed frequency and you will see a hint with exact Signal level (dBm), Frequency (MHz), Noise Floor (dBm),
indicators of RSSI (dBm), High RSSI (dBm), Max RSSI (dBm) and their values in dB.High RSSI allows you to estimate
the signal sources number, if the value is significantly different from the average RSSI, then there are several
sources of interference.
7.6 DFS menu
The "DFS
35
" page provides the monitoring and management of the DFS operation. The DFS status and availability
indicators are shown for each frequency for the given band and grid. The indicators are described in the Legend at
the bottom of the page.
By clicking the «Clear NOL» button, you clear the non-occupation list with the blocked frequencies (due to the
radars detected on these frequencies). The DFS subsystem rescans those frequencies and if they are still not
available, the scanning starts after the time period displayed in the right bottom corner of the frequency indicator.
By clicking the «Re-select Channel» button, you restart the DFS scanning.
