Table 24 - Spectrum Analyzer
Start/stop Spectrum Analyzer by pressing the «Start Sensor Test»/«Stop Sensor
Test» buttons.
By pressing 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), RSSI (dBm), High
RSSI (dBm), Max RSSI (dBm) values.

DFS
The DFS 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 pressing 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 pressing the «Re-select Channel» button, you restart the DFS scanning.
