The Usable Frequency menu includes the following options:
 Show: To display the current list
 Add Frequencies: To add one or several frequencies (in MHz) to the list, where
each entry is in the range from Minimum Frequency+1/2 Bandwidth up to a
maximum of Maximum Frequency-1/2 Bandwidth, using a resolution of 2.5
MHz for a 5 MHz Sector Bandwidth or 5 MHz for a Sector Bandwidth of 10 or
20 MHz. For more details refer to “Frequency” on page 164. Multiple entries
are separated by semi-colon (;).
 Delete Frequencies: To delete one or several frequencies (in MHz) from the list.

4.7.2.2.3 Spectrum Analyzer
The Spectrum Analyzer option enables initiating a spectrum analysis test on
selected frequencies, terminating an active test and viewing the results of the last
test.
Using the parameters defined for the test, the unit scans the selected central
frequencies. The frequencies to be scanned are all frequencies between the
defined Start Frequency and Stop Frequency, using a resolution of 2.5 MHz for a 5
MHz Sector Bandwidth or 5 MHz for a Sector Bandwidth of 10 or 20 MHz. At each
frequency it measures the RSSI for each of the applicable sub-carrier frequencies,
and calculates the median RSSI (for all sub-carriers) and the highest RSSI.
The Spectrum Analyzer menu includes the following options:
 Show
 Update Spectrum Analyzer General Parameters
NOTE
For units using a Country Code where DFS is not required by the relevant ETSI/FCC regulations for
certain sub-bands, frequencies in these sub-bands that are included in the Usable Frequencies List
are always considered as Available.
NOTE
The Spectrum Analysis test is a service affecting operation: Services to all units served by the
sector are disconnected for the duration of the test.
